TEXTILES, IMPLANTABLE MEDICAL DEVICES USING SUCH TEXTILES, AND

PROCESSES FOR MAKING THE SAME

CROSS-REFERENCE TO RELATED APPLICATIONS

[001] This application claims the benefit of U.S. Provisional Application No. 62/991 ,447, filed March 18, 2020, entitled Textiles and Implantable Medical Devices Using the Same, the content of which is incorporated herein by reference in its entirety.

FIELD

[002] The present application concerns aspects of textile materials made from a textured yarn, where at least a portion of the textile material has a 3-D honeycomb pattern having a plurality of cell units. The present application also concerns aspects of implantable medical devices comprising such textile materials.

BACKGROUND

[003] The heart can suffer from various valvular diseases or malformations that result in significant malfunctioning of the heart and ultimately require replacement of the native heart valve with an artificial valve. Human heart valves, which include the aortic, pulmonary, mitral, and tricuspid valves, function essentially as one-way valves operating in synchronization with the pumping heart. The valves allow blood to flow downstream but block blood from flowing upstream. Diseased heart valves exhibit impairments such as narrowing of the valve or regurgitation, which inhibits the valves' ability to control blood flow. Such impairments reduce the heart's blood pumping efficiency and can be a debilitating and life-threatening condition. For example, valve insufficiency can lead to conditions such as heart hypertrophy and dilation of the ventricle. Thus, extensive efforts have been made to develop methods and apparatuses to repair or replace impaired heart valves.

[004] Prostheses exist to correct problems associated with impaired heart valves. For example, mechanical and tissue-based heart valve prostheses can be used to replace impaired native heart valves. More recently, substantial effort has been dedicated to developing replacement heart valves, particularly tissue-based replacement heart valves that can be delivered with less trauma to the patient than through open-heart surgery. Replacement valves are being designed to be delivered through minimally invasive procedures and even percutaneous procedures. Such replacement valves often include a tissue-based valve body that is connected to an expandable frame that is then delivered to the native valve's annulus.

[005] These replacement valves are often intended to at least partially block blood flow. However, a problem occurs when blood flows around the valve on the outside of the prosthesis. For example, in the context of replacement heart valves, paravalvular leakage has proven particularly challenging. An additional challenge relates to the ability of such prostheses to be secured relative to intra-luminal tissue, e.g., tissue within any body lumen or cavity, in an atraumatic manner. Further challenges arise when trying to controllably deliver and secure such prostheses in a location such as at a native mitral valve. These replacement valves are often intended to at least partially block blood flow.

[006] Because of the drawbacks associated with conventional open-heart surgery, percutaneous and minimally-invasive surgical approaches are garnering intense attention. In one technique, a prosthetic valve is configured to be implanted in a much less invasive procedure by way of catheterization. For instance, U.S. Pat.

Nos. 5,411 ,522 and 6,730,118, which are incorporated herein by reference, describe collapsible transcatheter heart valves that can be percutaneously introduced in a compressed state on a catheter and expanded in the desired position by balloon inflation or by utilization of a self-expanding frame or stent. In yet another example, U.S. U.S. Publication Nos. 2014/0277390, 2014/0277422, 2014/0277427, and 2015/0328000, and 2019/0328515, which are incorporated herein by reference in their entirety, describe heart valve prostheses for replacing a native mitral valve including a self-expanding frame with a plurality of anchoring members that are designed be deployed within a body cavity and prevent axial flow of fluid around an exterior of the prosthesis. [007] However, problems still can occur. For example, in the context of replacement heart valves, paravalvular leakage has proven particularly challenging.

[008] An additional challenge relates to the ability of such prostheses to be secured relative to intra-luminal tissue, e.g., tissue within any body lumen or cavity, in an atraumatic manner. Further challenges arise when trying to controllably deliver and secure such prostheses in a location such as at a native mitral valve.

[009] These needs and others are at least partially satisfied by the present disclosure.

TEXTILE

[049] Disclosed herein is a textile defined by a first surface and an opposite second surface and having a longitudinal axis and a transverse axis, and having a first thickness, a first width, and a first length, and comprising: a plurality of weft yarns and a plurality of warp yarns arranged such that at least a portion of the first surface and/or the second surface of the textile has a 3-D honeycomb pattern having a plurality of repeating cell units, wherein at least one yarn of the plurality of warp yarns and/or the plurality of weft yarns is a textured yarn exhibiting a heat-shrinkage rate from about 10% to about 60%; wherein the textile has a first dimension in a relaxed position along the longitudinal axis, the transverse axis, and across of the textile, wherein the first dimension is defined by the first thickness, the first width, or the first length, and wherein the textile is configured to reversible arrive at a second dimension under application of stress, wherein the second dimension is defined by a second thickness, a second width, or a second length, and return to the first dimension upon removal of stress and wherein the textile is bio-compatible; and wherein the textile exhibits a first stress-relaxation response.

[050] In still further aspects, the first textile thickness can be from about 0.1 mm to about 10 mm, including exemplary values of about 0.2 mm, about 0.3 mm, about 0.4 mm, 0.5 mm, about 0.6 mm, about 0.7 mm, about 0.8 mm, about 0.9 mm, about 1 mm, about 1.5 mm, about 2 mm, about 2.5 mm, about 3 mm, about 3.5 mm, about 4 mm, about 4.5 mm, about 5 mm, about 5.5 mm, about 6 mm, about 6.5 mm, about 7 mm, about 8.5 mm, about 9 mm, and about 9.5 mm. In yet other aspects, the first textile thickness can have any values between any two foregoing values.

[051] In still further aspects, when the first textile length is from about 1 mm to about 100 mm, including exemplary values of about 2 mm, about 5 mm, about 7 mm, about 10 mm, about 12, mm, about 15 mm, about 17 mm, about 20 mm, about 22 mm, about 25 mm, about 27 mm, about 30 mm, about 32, mm, about 35 mm, about 37 mm, about 40 mm, about 42 mm, about 45 mm, about 47 mm, about 50 mm, about 52, mm, about 55 mm, about 57 mm, about 60 mm, about 62 mm, about 65 mm, about 67 mm, about 70 mm, about 72, mm, about 75 mm, about 77 mm, about 80 mm, about 82 mm, about 85 mm, about 87 mm, about 90 mm, about 92, mm, about 95 mm, and about 97 mm. It is understood that these values are exemplary and not limiting and that textiles can have any length values between any two foregoing values. It is further understood that the first length can be about 150 mm, about 200 mm, or about 1 m if the specified application requires it.

[052] In still further aspects, wherein the textile width is from about 1 mm to about 100 mm, including exemplary values of about 2 mm, about 5 mm, about 7 mm, about 10 mm, about 12, mm, about 15 mm, about 17 mm, about 20 mm, about 22 mm, about 25 mm, about 27 mm, about 30 mm, about 32, mm, about 35 mm, about 37 mm, about 40 mm, about 42 mm, about 45 mm, about 47 mm, about 50 mm, about 52, mm, about 55 mm, about 57 mm, about 60 mm, about 62 mm, about 65 mm, about 67 mm, about 70 mm, about 72, mm, about 75 mm, about 77 mm, about 80 mm, about 82 mm, about 85 mm, about 87 mm, about 90 mm, about 92, mm, about 95 mm, and about 97 mm. It is understood that these values are exemplary and not limiting and that textiles can have any width values between any two foregoing values. It is further understood that the first width can be about 150 mm, about 200 mm, or about 1 m if the specified application requires it

[053] It is understood that in the aspects of the current disclosure, when the comparison is made between the first and the second dimensions, the actual comparison is made between the first length in the relaxed position and the second length under the stress, or between the first width in the relaxed position and the second width under the stress, or between the first thickness in the relaxed position and the second thickness under the stress. It is further understood that the comparison is made between the first dimension and the second dimension in the same direction as the applied stress. For example, in the aspects where the stress is stretching applied along the longitudinal axis, the comparison is made between the first length along the longitudinal axis and the second length along the same stretch axis. In yet further aspects, where the stress is stretching applied along the transverse axis, the comparison is made between the first width along the transverse axis and the second width along the same stretch axis. In still further aspects, where the stress is compression applied across the first thickness of the textile, the comparison is made between the first thickness before application of the load and the second thickness obtained after the load has been applied.

[054] In still further aspects, the stress can comprise stretching the textile. While in other aspects, the stress can comprise compression of the textile.

[055] In the aspects where the stress comprises stretching the textile in one or more directions along the longitudinal, the transverse axis, or across of the textile, the second dimension selected from the second length or width is greater than 0 to about 300 %, including exemplary values of about 1 %, about 5 %, about 10 %, about 20 %, about 30 %, about 40 %, about 50 %, about 60 %, about 70 %, about 80 %, about 90 %, about 100 %, about 120 %, about 150 %, about 170 %, about 200 %, about 220 %, about 250 %, and about 260 of the first dimension selected from the first length or width, as measured in the stretch direction. It is further understood that the textiles disclosed herein can have a different response to the same stress as measured along the textile width, length, or thickness. For example, when the textile is stressed by stretching, the first length of the textile can change from the relaxed position to the second length that is greater than 0 % to about 300 % of the first length. However, it is also understood that in certain aspects, if the textile, for example, is stressed by stretching along the first length or along the longitudinal axis, while the second length can be greater than 0% to about 300%, the second width can shrink to greater than 0 % to about 300%, including exemplary values, of about 1 %, about 5 %, about 10 %, about 20 %, about 30 %, about 40 %, about 50 %, about 60 %, about 70 %, about 80 %, about 90 %, about 100 %, about 120 %, about 150 %, about 170 %, about 200 %, about 220 %, about 250 %, and about 260 % of the first width. Similarly, in certain aspects, if the textile, for example, is stressed by stretching along the first length or along the longitudinal axis, while the second length can be greater than 0% to about 300%, the second thickness can decrease by greater than 0 % to about 300%, including exemplary values of about 1 %, about 5 %, about 10 %, about 20 %, about 30 %, about 40 %, about 50 %, about 60 %, about 70 %, about 80 %, about 90 %, about 100 %, about 120 %, about 150 %, about 170 %, about 200 %, about 220 %, about 250 %, and about 260 % of the first thickness. It is further understood that the % in an increase of the first length, for example, can be the same or different from the % of decrease of the first width or thickness. It is further understood that the changes in the length, width, and/or thickness can be dependent on the direction of the applied stress. For example, and without limitations, in some aspects, the textiles disclosed herein can have the second thickness of about 90-95 % smaller than the first thickness when the textile is stretched by about 100-125 % in all directions. However, yet in other aspects, the disclosed textile can become rigid and/or less compressible with apparent higher thickness if stretched in only one direction.

[056] In still further aspects, the second dimension along each direction can be the same or different from the second dimension along the rest of the one or more directions. In some exemplary aspects, when for example, the stress comprises stretching the textile along its longitudinal axis, the second dimension defined by the second length can be the same or different when compared to the stretching the textile along its transverse axis or across the textile.

[057] In still further aspects, wherein the stress comprises compression across the first thickness of the textile and wherein the textile exhibits compressibility of 50- 95 %, including exemplary values of about 55 %, about 60 %, about 65 %, about 70 %, about 75 %, about 80 %, about 85 %, and about 90% of the first thickness under a loading force of about 45 to about 56 lbs, including exemplary values of about 46 lbs, about 47 lbs, about 48 lbs, about 49 lbs, about 50 lbs, about 51 lbs, about 52 lbs, about 53 lbs, about 54 lbs, and about 55 lbs. It is understood that the compressibility can be dependent on the first thickness of the textile. In still further aspects, it is understood that the compressibility can be measured as a function of the textile layers. In some aspects, the first thickness of the textile will be defined by a total thickness of each of the thicknesses of each textile layer.

[058] In certain aspects, the at least a portion of the first surface and the second surface has the 3-D honeycomb pattern.

[059] It is understood that the yarn path in honeycomb fabric can comprise interwoven curves and straight yarn floats. The length and altitude of yarn float, no matter whether in the warp or weft, are both increasing and then decreasing gradually and simultaneously. In such exemplary aspects, a periodicity and forming repeats of inverted pyramidal space can be formed on both surfaces of the fabric. Yet, in other aspects, the honeycomb design can be formed only on one surface of the fabric. In some exemplary aspects, in a honeycomb fabric, the part of a warp yarn underneath a weft float is a warp float. In still further aspects, two layers of floats can form a closed internal space. Without wishing to be bound by any theory, it is hypothesized that the periodical repeats of the inverted pyramidal space and the closed internal space in the honeycomb fabric can provide good sound and moisture absorption, good insulation, and a quick-dry rate. In general, the tensile strength of an interlaced plain-woven fabric is comparatively highest due to the interlacements of the yarns. However, without wishing to be bound by any theory, it is hypothesized that due to the existence of a yarn straight float, the mechanical properties, such as burst strength, compression, and shear of the textile can be improved when compared to an interlaced plain-woven fabric.

[060] In still further aspects, the plurality of warp yarn and the plurality of weft yarns can comprise the textured yarn. It is understood that the textured yarn can be prepared by any known in the art methods. In certain aspects, the textured yarn can be selected from a friction-textured yarn, a pin textured yarn, an air textured yarn, a belt textured yarn, a stuffer box textured yarn, or any combination thereof. Still, in further exemplary and unlimiting aspects, the textured yarn can be produced by friction texturing, or pin or false twist texturing, air texturing, stuffer box texturing, or any combination thereof. In still further exemplary aspects, the textured yarn is a friction-textured yarn.

[061] In still further aspects, the textured yarn can exhibit a heat-shrinkage rate from about 10 % to about 60%, including exemplary values of about 15 %, about 20%, about 25 %, about 30 %, about 35 %, about 40%, about 45 %, about 40 %, about 45 %, about 50%, and about 55 %. It is understood that the textured yarn can have a heat-shrinkage rate value between any two foregoing values.

[062] It is further understood that various textured yarns can have various degrees of texturizing. The degree of texturing is evaluated by measuring crimp contraction, stretch potential, and bulk ratio of the textured yarn. Without wishing to be bound by any theory, it is hypothesized that the degree of texturizing can have an impact on the shrinkage properties of the textile as well as the final bulkiness of the textile.

[063] In some aspects and as disclosed herein, each yarn of the plurality of weft yarns and/or warp yarns can comprise a plurality of fibers. In still further aspects, the textured yarn can comprise polyesters, co-polyesters, ultra-high molecular weight polyethylene, polyethylene, polypropylene, polytetrafluoroethylene, expanded polytetrafluorethylene, polyvinylidene fluoride, polyurethane, polyethers, polyureas, nylon, copolymers thereof, or a combination thereof. It is understood that the plurality of yarns present in the textile can comprise the same or different yarn. For example, in certain aspects, and without limitation, all yarns in the plurality of yarns are textured. In still further aspects, all textured yarns are the same. However, in other aspects, not all the yarns comprise the same textured yarn. In certain aspects, the yarns can be different by a type of material or a type of texturing method. Similarly, the plurality of yarns in the weft and warp direction can be the same or different.

[064] In still further aspects, each yarn of the plurality of weft yarns and/or warp textured yarns can have a size from about 10 to about 200 denier, including exemplary values of about 20 denier, about 50 denier, about 70 denier, about 100 denier, about 120 denier, about 150 denier, and about 170 denier. It is understood that each yarn of the plurality of weft yarns and/or warp yarns can have a denier value between any two foregoing values. For example, and without limitation, each yarn of the plurality of weft yarns and/or warp yarns can have a denier value from about 12 denier to about 25 denier, or from about 30 denier to about 85 denier, or from about 110 denier to about 185 denier.

[065] In still further aspects, each yarn of the plurality of weft yarns and/or warp textured yarns can comprise from about 8 to about 150 fibers, including exemplary values of about 10 fibers, about 15 fibers, about 20 fibers, about 50 fibers, about 70 fibers, about 100 fibers, and about 120 fibers. It is understood that each yarn of the plurality of weft yarns and/or warp yarns can comprise any number of fibers between any two foregoing values. For example, and without limitation, each yarn of the plurality of weft yarns and/or warp yarns can comprise from about 8 to 25 fibers or from about 27 fibers to about 85 fibers, or from about 110 fibers to about 145 fibers.

[066] In still further aspects, the fiber can have any diameter suitable for the desired application.

It is understood that the fiber can have any diameter between any two foregoing values. For example, and without limitation, the fiber can have a diameter from about 3 pm to about 8 pm, or from about 11 pm to about 22 pm, or from about 15 pm to about 25 pm. [067] In still further aspects, the textured yarn can have a second stress-relaxation response. It is understood that the second stress-relaxation response of the textured yarn can be the same or different from the first stress-relaxation response of the textile. It is further understood that in some exemplary aspects, the textured yarn is provided with the second stress-relaxation response by the yarn manufacturer. While in other aspects, the second stress-relaxation response can be provided to the yarn prior to weaving it into the textile by a skilled practitioner.

[068] In still further aspects, the first stress-relaxation response can be defined by first heat-set conditions of the textile and the second stress-relaxation response. As discussed in detail above, the first stress-relaxation response can be the same as the second stress-relaxation response or different.

[069] In certain aspects and as disclosed herein, the first and/or second heat-set conditions can comprise a heat-set temperature from about 90 °C to about 220 °C, including exemplary values of about 95 °C, about 100 °C, about 110 °C, about 120 °C, about 130 °C, about 140 °C, about 150 °C, about 160 °C, about 170 °C, about 180 °C, about 190 °C, about 200 °C, and about 210 °C.

It is understood that the first and/or second heat-set conditions can have any heat-setting time between any two foregoing values. For example, and without limitation, the heat-setting time can be from about 5 min to about 20 min, or from about 7 min to about 25 min, or from about 15 min to about 60 min. [071] In still further aspects, the first and/or second heat-set conditions can comprise a heat-set temperature from about 90 °C to about 220 °C, including exemplary values of about 95 °C, about 100 °C, about 110 °C, about 120 °C, about 130 °C, about 140 °C, about 150 °C, about 160 °C, about 170 °C, about 180 °C, about 190 °C, about 200 °C, and about 210 °C, and a heat setting time from about 2 min to about 1 h, including exemplary values of about 5 min, about 10 min, about 15 min, about 20 min, about 25 min, about 30 min, about 35 min, about 40 min, about 45 min, about 50 min, and about 55 min.

IMPLANTABLE MEDICAL DEVICE

[083] Paravalvular leak (PVL) is a complication associated with the implantation of a prosthetic heart valve. PVL refers to blood flowing through a channel between the structure of the implanted valve and cardiac tissue as a result of a lack of appropriate sealing. The majority of PVL are crescent, oval, or roundish-shaped, and their track can be parallel, perpendicular, or serpiginous. Transcatheter Heart Valve (THV) procedures generally use either a substantially inelastic woven cloth or a stretchable knitted cloth for PVL sealing.

[084] When comparing the woven cloth with the knitted cloth for PVL sealing, the substantially inelastic woven cloth has the advantage of providing better dimensional stability that helps in procedures dealing with joining the valve components together using sutures and laser cutting of components. Further, the pore sizes and pore densities in a woven cloth can be engineered to balance sealing and tissue in-growth functions. On the other hand, knitted cloth provides better stretchability than woven cloth construction. Stretchability helps in reducing stress on a tissue to which the medical device comprising the textile is attached.

[085] With the next generation of THV frame designs that have changing frame dimensions, one of the requirements is to have the PVL seal cloth and/or the frame inner cloth to adapt to the changing frame dimensions. Thus, there is a need for a cloth having controlled stretchability and lower profile to provide improved compliance by reducing potential stresses at locations where the cloth is secured to a bodily lumen.

[086] The present disclosure describes the aspects addressing the issues disclosed above. In one aspect, described herein is an implantable medical device comprising: an annular frame having an inflow end, an outflow end, and a longitudinal axis; and a sealing element secured to the frame, wherein the sealing element comprises: textile defined by a first surface and an opposite second surface and having a longitudinal axis and a transverse axis and having a first thickness, a first width, and a first length, and comprising: a plurality of weft yarns and a plurality of warp yarns arranged such that at least a portion of the first surface and/or the second surface of the textile has a 3-D honeycomb pattern having a plurality of repeating cell units, wherein at least one yarn of the plurality of warp yarns and/or the plurality of weft yarns is a textured yarn exhibiting a heat-shrinkage rate from about 10% to about 60%; wherein the textile has a first dimension in a relaxed position along the longitudinal axis, the transverse axis, and across of the textile, wherein the first dimension is defined by the first thickness, the first width, or the first length, and wherein the textile is configured to reversible arrive at a second dimension under application of stress, wherein the second dimension is defined by a second thickness, a second width, or a second length, and return to the first dimension upon removal of stress and wherein the textile is bio-compatible; and wherein the textile exhibits a first stress-relaxation response; and wherein the implantable medical device is configured to radially collapse to a collapsed configuration and radially expand to an expanded configuration.

[087] It is understood that any of the textiles described above can be used in the disclosed implantable medical device.

[088] In still further aspects, the applied stress can comprise stretching the textile in one or more directions along the longitudinal, the transverse axis, or across of the textile, the second dimension selected from the second length or width is greater than 0 to about 300 %, including exemplary values of about 1 %, about 5 %, about 10 %, about 20 %, about 30 %, about 40 %, about 50 %, about 60 %, about 70 %, about 80 %, about 90 %, about 100 %, about 120 %, about 150 %, about 170 %, about 200 %, about 220 %, about 250 %, and about 260 % of the first dimension selected from the first length or width, as measured in the stretch direction. It is further understood that the textiles disclosed herein can have a different response to the same stress as measured along the textile width, length, or thickness. For example, when the textile is stressed by stretching, the first length of the textile can change from the relaxed position to the second length that is greater than 0 % to about 300 % of the first length. However, it is also understood that in certain aspects, if the textile, for example, is stressed by stretching along the first length or along the longitudinal axis, while the second length can be greater than 0% to about 300%, the second width can shrink to greater than 0 % to about 300% of the first width. Similarly, in certain aspects, if the textile, for example, is stressed by stretching along the first length or along the longitudinal axis, while the second length can be greater than 0% to about 300%, the second thickness can shrink to greater than 0 % to about 300% of the first thickness. It is understood that the textile used in these devices can comprise any textiles having any properties disclosed above.

[089] In still further aspects, the applied stress can comprise compression across the first thickness of the textile, and wherein the textile exhibits compressibility of 50- 95 %, including exemplary values of about 55 %, about 60 %, about 65 %, about 70 %, about 75 %, about 80 %, about 85 %, and about 90% of the first thickness under a loading force of about 45 to about 56 lbs, including exemplary values of about 46 lbs, about 47 lbs, about 48 lbs, about 49 lbs, about 50 lbs, about 51 lbs, about 52 lbs, about 53 lbs, about 54 lbs, and about 55 lbs. While in other aspects, the applied stress can comprise an expansion of the medical device to arrive at the expanded configuration.

[090] The exemplary aspects of the implantable medical device are shown in FIGS. 5-6. One exemplary and unlimiting aspect encompasses medical devices that are prosthetic heart valves. For example, and without limitation, FIG. 5 illustrates an exemplary aspect of a radially collapsible and expandable prosthetic valve 10 shown in its deployed, expanded configuration. The prosthetic valve can include an annular stent or frame 12, and a leaflet structure 14 situated within and coupled to the frame 12. The frame 12 can have an inflow end portion 16 and an outflow end portion 18. The leaflet structure can comprise a plurality of leaflets 22. In certain aspects, the leaflet structure can comprise three leaflets. In such exemplary aspects, such three leaflets can be arranged to collapse in a tricuspid arrangement similar to the aortic valve. Alternatively, the prosthetic valve can include two leaflets 22 configured to collapse in a bicuspid arrangement similar to the mitral valve, or more than three leaflets, depending upon the particular application. The prosthetic valve 10 can define a longitudinal axis 24 extending through the inflow end portion 16 and the outflow end portion 18.

[091] The frame 12 can be made of various biocompatible materials, such as stainless steel or a nickel-titanium alloy (“NiTi”), for example, Nitinol. With reference to FIG. 5, the frame 12 can include a plurality of interconnected lattice struts 26 arranged in a lattice-type pattern and forming a plurality of apices 28 at the outflow end 18 of the prosthetic valve. The struts 26 can also form similar apices at the inflow end 16 of the prosthetic valve (which are covered by a skirt 30 described in greater detail below). The lattice struts 26 are shown positioned diagonally or offset at an angle relative to and radially offset from the longitudinal axis 24 of the prosthetic valve. It is understood that the configuration depicted in FIG. 5 is exemplary only, and in other aspects, the lattice struts 26 can be offset by a different amount than depicted in FIG. 5 or some or all of the lattice struts 26 can be positioned parallel to the longitudinal axis of the prosthetic valve.

[092] The lattice struts 26 can be pivotably coupled to one another. In the illustrated aspect, for example, the end portions of the struts 26 forming the apices 28 at the outflow end 18 and at the inflow end 16 of the frame can have a respective opening 32. The struts 26 also can be formed with apertures 34 located between the opposite ends of the struts. Respective hinges can be formed at the apices 28 and at the locations where struts 26 overlap each other between the ends of the frame via fasteners 36, which can comprise rivets or pins that extend through the apertures 32, 34. The hinges can allow the struts 26 to pivot relative to one another as the frame 12 is expanded or contracted, such as during assembly, preparation, or implantation of the prosthetic valve 10. For example, the frame 12 (and, thus, the prosthetic valve 10) can be manipulated into a radially compressed or contracted configuration, coupled to a delivery apparatus, and inserted into a patient for implantation. Once inside the body, the prosthetic valve 10 can be manipulated into an expanded state and then released from the delivery apparatus. Additional details regarding the frame 12, the delivery apparatus, and devices and techniques for radially expanding and collapsing the frame can be found in U.S. Publication No. 2018/0153689, which is incorporated herein by reference. Additional details about such an exemplary prosthetic valve can also be found in U.S. Publication No. 2019/0046314, which is incorporated herein by reference.

[093] As further illustrated in FIG. 5, the prosthetic valve 10 can include a sealing element configured as a skirt 30. The skirt 30, as shown herein, can comprise any textile materials disclosed above. It is understood that in some aspects, the skirt 30 is an outer skirt. In such aspects, another skirt (not shown) known as an inner skirt can be attached to the frame underneath of the outer skirt 30. However, in some aspects, the textile materials used in the outer skirt 30 can also be used in the inner skirt (not shown here). Yet, in some aspects, the inner skirt does not comprise the textile materials used in the outer skirt. In still further aspects, only one skirt is used. In such aspects, such a skirt can comprise any of the textile materials described herein.

[094] The skirt 30 can be configured to establish a seal with the native tissue at the treatment site to reduce or prevent paravalvular leakage. The skirt 30 can include a main body portion 38 disposed about an outer circumference of the frame 12. The skirt 30 can be secured to the frame by, for example, a plurality of sutures 41 extending in a zig-zag pattern along selected strut members 26 between a first edge portion (e.g., an inflow edge portion) 40 and a second edge portion (e.g., an outflow edge portion) 42 of the skirt 30. For example, in certain aspects, the skirt 30 can be sutured to the frame 12 along a suture line 66 corresponding to a scalloped edge defined by the leaflets 22, which can allow the valve to radially expand and contract without interference from or pinching of the skirt. Further details regarding transcatheter prosthetic heart valves, including the manner in which the leaflets 22 can be coupled to the frame 12, can be found, for example, in U.S. Pat. Nos. 6,730,118, 7,393,360, 7,510,575, 7,993,394, and 8,652,202, which are incorporated herein by reference in their entireties.

[095] It is understood that the skirt 30 comprising the disclosed herein textile materials provides better dimensional stability that helps in procedures dealing with joining the valve components together using sutures and laser cutting of components. In still further aspects, it is understood that the presence of a 3-D honeycomb cellular structure of the disclosed textile allows balancing sealing and tissue in-growth functions. In yet further aspects, the controlled stretchability of the disclosed textile allows the reduction of the valve stresses on a tissue to which the medical device comprising the textile is attached. The disclosed textile allows the skirt 30 to adapt to the changing frame dimensions and provides a low profile for such a skirt.

[096] FIG. 6 illustrates a prosthetic valve 10, including another aspect of a sealing member or skirt 600. In the illustrated and unlimiting aspect, the skirt 600 comprises a textile material as described herein and configured as a fabric strip 602 having an edge portion 608. In certain exemplary aspects, the skirt 600 can be secured to struts 26 to form layers of the skirts (not shown). It is further understood that any configurations of the skirt coupling with the frame can be used depending on the desired application.

[097] The textile material described herein can be used in any sealing element aspect and in any combination with any of the prosthetic valves and/or frame aspects. It is understood that a prosthetic heart valve can also include any of the textile materials described herein, or portions thereof, in any combination.

[098] The textiles of the prosthetic sealing members described herein can be configured to promote a biological response in order to form a seal between the prosthetic valve and the surrounding anatomy. In certain configurations, the sealing elements described herein can be configured to form a seal over a selected period of time. For example, in certain aspects, the presence of the 3-D honeycomb cellular pattern, open, porous nature of filaments, yarns, etc., can allow a selected amount of paravalvular leakage around the prosthetic valve in the time period following implantation. The amount of paravalvular leakage past the seal structure may be gradually reduced over a selected period of time as the biological response to the textile causes blood clotting, thrombus formation, etc. In some aspects, the sealing members, and in particular the 3-D honeycomb cellular pattern of the textile, filaments, yarns, etc., of the paravalvular sealing structure, can be treated with one or more agents that inhibit the biological response to the sealing structures. For example, in certain exemplary aspects, the textiles having a 3-D honeycomb cellular pattern or separated yarns and fibers can be treated with heparin. In certain aspects, the amount or concentration of the agent(s) can be selected such that the agents are depleted after a selected period of time (e.g., days, weeks, or months) after valve implantation. As the agent(s) are depleted, the biological response to the textile or yarns or fibers of the sealing structures can increase such that a paravalvular seal forms gradually over a selected period of time. This can be advantageous in patients suffering from left atrial remodeling (e.g., due to mitral regurgitation) by providing an opportunity for the remodeling to reverse as regurgitation past the prosthetic valve is gradually reduced.

[099] In still further aspects disclosed is an implantable medical device comprising: a self-expanding frame having an upper region, an intermediate region and a lower region, wherein the frame is configured to radially expand and contract for deployment within a body cavity, and wherein the self-expanding frame comprises a plurality of anchoring members disposed along the lower region; wherein at least a portion of at least some of the plurality of anchoring members is enclosed within a textile material, wherein the textile material is defined by a first surface and an opposite second surface, having a longitudinal axis and a transverse axis, and having a first thickness, a first width, and a first lengths, and comprising: a plurality of weft yarns and a plurality of warp yarns arranged such that at least a portion of the first surface and/or the second surface of the textile has a 3-D honeycomb pattern having a plurality of repeating cell units, wherein at least one yarn of the plurality of warp yarns and/or the plurality of weft yarns is a textured yarn exhibiting a heat-shrinkage rate from about 10% to about 60%; wherein the textile exhibits a first stress-relaxation response; and wherein the textile material is biocompatible and behaves as a cushion, and the textile exhibits compressibility of 50-95 % of the first thickness under a loading force of about 45 to about 56 lbs. These exemplary aspects of such implantable medical devices are shown in FIGS. 7-10. One exemplary aspect of the possible frame is shown in FIG. 7. Such an exemplary frame 720 can have a proximal end 722 and a distal end 724. In some aspects, such as the illustrated aspect, the frame 720 can include an intermediate portion 726, which has a greater diameter than the diameter of the frame 720 at the proximal and/or distal ends 722, 724 when the frame 720 is in an expanded configuration.

The frame 720 can be designed to expand radially and contract for deployment within a body cavity, such as at a heart valve location such as the mitral valve. For example, as described in greater detail in U.S. Publication Nos. 2014/0277390, 2014/0277422, and 2014/0277427, the frame 720 can include a plurality of struts, which define a plurality of foreshortening cells.

The distal anchors 730 can be designed such that when the frame 720 is in an expanded configuration, an end or tip 732 of each distal anchor 730 is positioned radially outward from the frame 720 and extends generally in a proximal direction. In some aspects, the disclosed exemplary implantable medical device can optionally include one or more proximal anchors 734. The proximal anchors 734 can be positioned along or proximate a proximal end 722 of the frame 720 and can be connected to the frame 720. The proximal anchors 734 can be designed such that when the frame 720 is in an expanded configuration, an end or tip 736 of each proximal anchor 734 is positioned radially outward from the frame 720 and extends generally in a distal direction.

[0101] Another aspect of the exemplary frame 800 is shown in FIG. 8. In such an aspect, the frame 800 is shown in an expanded configuration. The frame 800 can include a frame portion 802 having an upper region 810, an intermediate region 820, and a lower region 830. In certain aspects, the intermediate portion 820 can have a greater diameter than the diameter of the frame 800 at the proximal and/or distal ends 810 and 830 when the frame 800 is in an expanded configuration. In some aspects, such as the illustrated aspect, the frame 800 can include an intermediate portion 820, which has a greater cross-sectional area than the cross-sectional area of the frame 800 at the proximal and/or distal ends 810 and 830 when the frame 800 is in an expanded configuration. A longitudinal axis (not shown) of the frame 800 may be defined as the central axis that extends through the center of the frame 800 between the upper and lower ends of the frame 800. In some aspects, the frame 800 may be oriented such that the upper region 810 is a proximal portion, and the lower region 830 is a distal portion. The frame 800 can include a plurality of anchoring members 850. In some aspects, the frame 800 may be oriented such that the plurality of anchoring members 850 are a distal anchoring members. As shown in the illustrated aspect, the plurality of anchoring members 850 can include one or more anchors. For example, and without limitation, as shown in the illustrated aspect, the plurality of anchoring members 850 can include nine anchors, each including a strut 852 extending from a lower region 830 of the frame body 802 and a tip 853.

[0102] An exemplary and unlimiting anchoring member 900 is shown in FIGS. 9A and 9B. It is understood that this anchoring member 900 is only exemplary, and any other configurations of the anchoring members can be present. The exemplary member 900 can between a collapsed configuration (as shown in FIG. 9A) and an expanded configuration (as shown in FIG. 9B). In transitioning from the collapsed configuration to the expanded configuration, the lateral dimension (or width) of the anchoring member 900 can increase.

An exemplary and unlimiting aspect is shown in FIG. 10. FIG. 10 shows a photograph of a frame, similar to one shown in FIG. 8, having a plurality of anchoring members 850 each having a strut 852 and a tip 853. A textile material described herein is used to form a cushion 1000 around the struts and tips of the plurality of anchoring members. In certain aspects, the cushion 1000 can be formed from two separate pieces of the disclosed textile, such as an inner portion positioned within a covering such that the covering forms a layer surrounding the inner portion.

In yet other aspects, the cushion 1000 can be formed by the enclosure of the at least a portion of at least some of the plurality of anchoring members is formed by one or more layers of the textile material. It is understood that these layers of the textile material can be formed by separate fabrics or by one fabric wrapped around the anchoring members in any desired fashion.

[0104] In still further aspects, the enclosure can optionally comprise other materials that are different from the disclosed textile material. For example, and without limitation, if the enclosure comprises an inner and outer portion, the inner portion can comprise a textile structure such as a braided, knitted or woven cloth sleeve, while the outer portion comprises the disclosed herein textile material. It is understood that the use of the cushions 1000 on the anchoring members can maintain a smaller form factor while the implantable medical device is in a contracted state for delivery. It is understood that the aspects described herein include an aspect that only some of the plurality of the anchoring members are enclosed in the disclosed textile. Yet other aspects described herein include all of the plurality of the anchoring members being enclosed in the disclosed textile. In still further aspects, only a portion of the anchoring members is enclosed, while in other aspects, a full body of the anchoring members is enclosed with the textile material.

[0105] It is understood that in certain aspects, cushions, similar but are not limited to those shown in FIG. 10, can advantageously increase the contact area of the plurality of anchor members on the tissue. It can further reduce trauma between the plurality of anchor members and such tissue. Moreover, this can facilitate the growth of tissue in and/or around the plurality of anchor members. Even further, the disclosed herein cushions can also beneficially reduce any potential trauma that can be caused when an adjacent anchor member to the cushioned anchor member does not have a disclosed cushion. It is further understood that a final thickness of each of the enclosures around any or all of the plurality of anchoring members can be the same or different and can be selected based on the specific application. Some of the plurality of anchoring members can have an enclosure within the disclosed textile such that the final thickness of the enclosure can be thicker than the final thickness of the enclosures.

In still further aspects, the textile formed by the disclosed methods can comprise any textile disclosed above. In still further aspects and as disclosed herein, the textured yarn used to form the disclosed textile can have a second stress-relaxation response.

[0110] In still further aspects, the methods disclosed herein comprise a step of exposing the textile to first heat-set conditions effective to provide the first stress- relaxation response of the textile.

[0111] In some aspects, it is understood that the first stress-relaxation response of the textile can only be defined by the first heat-set conditions. While, in other aspects, the first stress-relaxation response of the textile can be defined by the combination of the first heat-set conditions and the second stress-relaxation response of the textured yarn used in the textile. It is understood that the second stress-relaxation response of the textured yarn can be obtained by second heat-set conditions. It is further understood that the second heat-set conditions can be applied to the textured yarn during the yarn manufacturing or at any other step if the manufacturing conditions allow that.

[0112] In still further aspects, the first and/or second heat-set conditions can be obtained by the heat setting temperature or heat exposure time or a combination of both.

[0113] In certain aspects and as disclosed herein, the first and/or second heat-set conditions can comprise a heat-set temperature from about 90 °C to about 220 °C, including exemplary values of about 95 °C, about 100 °C, about 110 °C, about 120 °C, about 130 °C, about 140 °C, about 150 °C, about 160 °C, about 170 °C, about 180 °C, about 190 °C, about 200 °C, and about 210 °C. It is understood that the first and/or second heat-set conditions can have a heat-set temperature value that is any value between any two foregoing values. For example, and without limitation, the heat-set temperature can be from about 90 °C to about 120 °C, or from about 100 °C to about 180 °C, or from about 150 °C to about 220 °C.

[0114] In still further aspects, the first and/or second heat-set conditions can comprise a heat setting time from about 2 min to about 1 h, including exemplary values of about 5 min, about 10 min, about 15 min, about 20 min, about 25 min, about 30 min, about 35 min, about 40 min, about 45 min, about 50 min, and about 55 min. It is understood that the first and/or second heat-set conditions can have any heat-setting time between any two foregoing values. For example, and without limitation, the heat-setting time can be from about 5 min to about 20 min, or from about 7 min to about 25 min, or from about 15 min to about 60 min.

[0115] In still further aspects, the first and/or second heat-set conditions can comprise a heat-set temperature from about 90 °C to about 220 °C, including exemplary values of about 95 °C, about 100 °C, about 110 °C, about 120 °C, about 130 °C, about 140 °C, about 150 °C, about 160 °C, about 170 °C, about 180 °C, about 190 °C, about 200 °C, and about 210 °C, and a heat setting time from about 2 min to about 1 h, including exemplary values of about 5 min, about 10 min, about 15 min, about 20 min, about 25 min, about 30 min, about 35 min, about 40 min, about 45 min, about 50 min, and about 55 min.

[0116] It is further understood that any methods of heating can be used depending on the desired application. In certain and unlimiting aspects, the heat setting can be performed using a hot-air environment when the textile is in a relaxed state. However, it is understood that in some aspects, the heat-set can also be performed on the textile when a stress is applied to the textile if the desired application requires it.

[0117] An exemplary heat-setting feature is shown in FIG. 11. The feature is utilized to control the tension on the cloth in two directions or in all four directions during heat setting. This tensioning system with heat-setting parameters allows the cloth to have controlled shrinkage. An example tensioning system includes a rectangular base with a threaded rod extending between opposing sides of the base. Pin racks 1104 are mounted to the threaded rods. Each of the pin racks 1104 includes at least one pin that couples to/engages the cloth. The cloth is mounted on each of the pin racks 1104, and a tensioning knob 1102 is used to control the tension on the cloth by moving the pin racks 1104 along the threaded rods. For example, moving the pin racks 1104 outwards/towards the sides of the base will increase tension, stretching the cloth. Whereas moving the pin racks 1104 inwards releases the tension, relaxing the cloth.

[0118] In still further aspects, any of the described above textiles can be produced by the disclosed herein methods.

[0119] The present disclosure also provides for a method of making an implantable medical device comprising: providing a sealing element comprising a textile material defined by a first surface and an opposite second surface and having a longitudinal axis and a transverse axis, and having a first thickness, a first width, and a first length, and comprising: a plurality of weft yarns and a plurality of warp yarns arranged such that at least a portion of the first surface and/or the second surface of the textile has a 3-D honeycomb pattern having a plurality of repeating cell unit, wherein at least one yarn of the plurality of warp yarns and/or the plurality of weft yarns is a textured yarn exhibiting a heat-shrinkage rate from about 10% to about 60%; wherein the textile has a first dimension in a relaxed position along the longitudinal axis, the transverse axis, and across of the textile, wherein the first dimension is defined by the first thickness, the first width, or the first length, and wherein the textile is configured to reversible arrive at a second dimension under application of stress, wherein the second dimension is defined by a second thickness, a second width, or a second length, and return to the first dimension upon removal of stress and wherein the textile is bio-compatible; and wherein the textile exhibits a first stress-relaxation response; and securing the sealing element to an annular frame of the implantable medical device.

[0120] In still further aspects, any of the implantable medical devices disclosed herein can be formed by such methods. In still further aspects, any of the disclosed herein textiles can be used to form the sealing element of the device. In still further aspects, any methods commonly used to secure the sealing element to an annular frame can be used, for example, and without limitation, the sealing element can be secured to the annular frame of the device with a suture.

EXAMPLES

[0124] The following examples are put forth so as to provide those of ordinary skill in the art with a complete disclosure and description of how the compounds, compositions, articles, devices and/or methods claimed herein are made and evaluated and are intended to be purely exemplary and are not intended to limit the disclosure. Efforts have been made to ensure accuracy with respect to numbers ( e.g ., amounts, temperature, etc.), but some errors and deviations should be accounted for.

[0125] Unless indicated otherwise, parts are parts by weight, temperature is degrees C or is at ambient temperature, and pressure is at or near atmospheric or full vacuum.

[0126] A textile 100 having a longitudinal axis 102 (y-axis) and a transverse axis 104 (x-axis), as shown in FIG. 1, for example, was constructed on a weaving machine. The textile construction uses 16 pick repeat honeycomb weave using 40denier/27filament textured yarn in warp and weft direction. As described above, in some exemplary aspects, the weave pattern forms a repeated pattern of inverted and raised space on both surfaces of the textile 100. As illustrated in FIGS. 1-4, the honeycomb weave results in a repeating pattern of cells 106 and ridges 108, shown here on one side of the textile 100. The cells 106 are bounded between adjacent longitudinal and transverse extending ridges 108. As provided in FIGS. 1-4, the ridges 108a extend substantially parallel with the longitudinal axis 102 of the textile 100 and ridges 108b extend substantially parallel with the transverse axis 104 of the textile 100. The spacing between the longitudinal ridges 108a and the transverse ridges 108b is determined generally based on the pick repeat of the pattern (i.e., the number of cells 106 per square inch of the honeycomb pattern). As illustrated in FIGS. 1-4, the longitudinal ridges 108a and the transverse ridges 108b can be equally spaced along the width and length of the textile 100, respectively. Though not illustrated, other weave patterns are contemplated that to vary the spacing between the longitudinal and transverse ridges 108a, 108b. For example, the transverse ridges 108b may have an increased spacing compared to the spacing of the longitudinal ridges 108a, and vice versa. Likewise, the spacing between adjacent longitudinal and the transverse ridges 108b, 108a may vary along the length and width of the textile. Similarly, other weave patterns are contemplated to vary the orientations/angles of the longitudinal and transverse ridges 108a, 108b (with respect to the longitudinal and transverse axis 102, 104, respectively). For example, the longitudinal ridges 108a can be oriented at an angle with respect to the longitudinal axis 102 and/or the transverse ridges 108b can be oriented at an angle with respect to the transverse axis 104 of the textile. FIGS. 1-4 illustrate the ridges 108 defining square/rectilinear-shaped cells 106. Based on changes in the spacing and/or orientation of the longitudinal and transverse ridges 108a, 108b in the weave pattern, different shaped cells 106 can be formed (e.g., rectangular, diamond). As described above, the honeycomb weave forms in some aspects a 3-D honeycomb pattern forms an inverted space on both surfaces of the textile 100. That is, in such exemplary aspects, on each side of the textile, at least a portion of cells 106 extends in a direction away from the ridges 108 (e.g., extend in a direction along a z-axis of the textile 100 (perpendicular to both the longitudinal axis 102 and the transverse axis 104). FIGS. 2-4 show the same textile exposed to different heat-setting conditions. In FIG. 2, the textile has been exposed to 90 °C for 10 min, while in FIG. 3, the textile has been exposed to 120 °C for 10 min, and in FIG. 4 to 180 °C for 10 min. Temperature and heat exposure time increases result in a corresponding increase in at least one yarn of the thickness, compressibility and stretchability of the textile. For example, a higher temperature and time combination results in higher thickness, compressibility and stretchability. Flowever, the increase in each of these properties is limited by the available spaces between yarns, which correlates to the density of yarns in the cloth.
