CLAIM OF PRIORITY

[0001] This application claims the benefit of U. S. Provisional Patent Application Serial No. 63/170,760, filed on April 5, 2021, the benefit of priority of which is claimed hereby, and which is incorporated by reference herein in its entirety.

FIELD OF THE DISCLOSURE

[0001] The present subject matter relates to surgical procedures and devices and, more particularly, to prostheses, methods and systems related to soft tissue repair.

BACKGROUND

[0002] The successful reattachment of soft tissue to other tissue and/or bone can be a significant concern, especially in the sports medicine industry. Soft tissues are often fixed to various positions on the bone. For example, to replace a natural tendon fixation point or to replace the tendon itself, fixing a graft to a selected bone area may be desired. Thus, one means to fix a soft tissue to the selected area is to provide a suture through a selected portion of the soft tissue and fix the other end of the suture to a selected area on the bone with anchor(s) and/or tack(s).

DETAILED DESCRIPTION

[0005] Disclosed herein are methods, systems and devices that can facilitate a higher friction area on a suture and/or can facilitate a rapid connection of an element (a knot, another suture, a bead, and/or another surgical device) with the suture. For example, the systems and devices can facilitate the passage of part of the suture through an aperture created in the same suture. As a result of the suture being passed through itself, an initial loop is formed. This initial loop can be used for connection to the element or surgical device, for example. The initial loop can be reduced by drawing the suture through the aperture until the loop is closed (i.e., substantially eliminated) leaving a bump, ridge, projection or other feature along a surface of the suture. This surface feature can cause a higher friction area along the suture surface, and therefore, can be more inclined to contact, catch, grasp and/or hold soft tissue, for example. The surface feature can be helpful in creating a higher friction area so that the suture is less likely to slip against itself. Thus, the surface feature can decrease he likelihood of a slip of the suture, such as a suture knot slipping along a length of the suture. The surface feature can be helpful in coupling with tissue to facilitate coupling between the tissue and the suture. The size of the surface feature can be altered as desired by adding the element (e.g., the knot, the bead, etc.) to create a larger region along the suture of increased size for the feature. Multiple apertures and multiple passes of the suture through the aperture are contemplated to create regions of higher friction having multiple surface features along the longitudinal length of the suture.

[0006] The present inventors have recognized, among other things, that existing sutures can require a multiple step process for connection of the suture to tissue or for connection with another surgical device such as a suture anchor. This process can be challenging and time consuming. For example, currently known knotless suture anchor constructs typically rely on multiple components that must interact with one another precisely and in a reliable manner to facilitate anchoring of suture. Furthermore, sutures can have coatings or can be formed of material(s) that do not facilitate adequate friction with tissue to cause desired coupling (e.g., catching/grasping) of the suture with tissue or with itself (hence, the suture can possibly slip as discussed previously).

[0007] Considering these and other factors, the present inventors propose sutures and related systems and methods that can provide for faster, easier, and more reproducible surgical techniques. The suture and related systems and methods can be constmcted/performed with little additional components or complex techniques but by simply using an aperture through the suture and passing a part of that suture through the aperture and reducing the initial loop to create the feature. The suture, systems and methods disclosed herein can allow a surgeon to fasten suture to tissue or couple suture to a surgical device such as an anchor without tying a knot. Again, this can simplify surgical complexity.

[0008] Turning now to the figures, FIGS. 1 and 1 A show's a surgical suture 10 configured for connection to tissue. The suture 10 can include a body 12 having an exterior surface 14. The body 12 can comprise an elongate strand 16 having a longitudinal extent along a longitudinal axis LA. The elongate strand 16 can comprise a single strand or a plurality of strands. The plurality of strands can be woven, braided or otherwise interconnected.

[0009] The suture 10 can be any type of suture known in the art. Thus, the suture 10 can comprise a multi-strand or mono-strand suture. The suture 10 can be braided or n on-braided. The suture 10 can have any shape such as round, flat, broad band, tape, ribbon, etc. The suture 10 can be constructed of any material as known in the art. Examples of suitable sutures include, but are not limited to, ZipLoop™, BroadBand™, MaxBraid, TRU-Link and ExpressBraid™ sutures of Zimmer Biomet, Inc. The suture 10 can be formed of various materials such as but not limited to ultra-high-molecular weight polyethylene, other types of polyethylene, Nylon, etc., for example. [0010] FIGS. 1 and 1 A show' the suture 10 is a ribbon or band type suture formed of a plurality of braids and can be flat and broad rather than round. However, round suture is also contemplated as benefiting from the constructs and techniques discussed herein. Due to the ribbon or band type configuration shown, the suture 10 can have a first side 30 that is substantially flat and an opposing second side 32 that is substantially flat as shown in FIG. I A. The first side 30 and the second side 32 can extend generally parallel with one another.

[0011] FIGS. 2 and 2A show ⁷ a system 18 that includes the suture 10 and a needle 20. The needle 20 can include a tip 22 (FIG. 2) and snare loop 24. The suture 10 can include an aperture 26, in addition to the body 12, exterior surface 14 and elongate strand 16. [0012] The needle 20 can have an elongate length from the tip 22 at one end to the snare loop 24 at an opposing end. It is also contemplated that in alternative to a snare loop 24, the needle 20 could simply have an eye or other feature capable of capturing the suture 10 as known in the art. The tip 22 can be configured as a point can be configured to puncture the suture 10 as shown in FIGS. 2 and 2A. This puncture can create the aperture 26 as shown. The aperture 26 can be made at a first portion 28 of the elongate strand 16 of the body 12. The first portion 28 can be a part of the longitudinal length of the suture 10, for example. The aperture 26 can be formed in a manner that does not weaken the suture 10 such as by being positioned between the individual strands that make up the braids of the suture 10. Thus, the aperture 26 can be formed without breaking any of the strands that form the suture 10. The aperture 26 can pass in generally a lateral direction (give or take 60 degrees or so) through the elongate strand 16 relative to the longitudinal extent. The aperture 26 can be enclosed laterally on several sides by the body 12 of the suture 10. Thus, the aperture 26 can have only two openings. One opening of the aperture 26 can be on the first side 30 of the suture and another opening can be on the second opposing side 32 of the suture. As the suture 10 shown in FIGS. 2 and 2A is a ribbon suture, the first side 30 and the second side 32 can be substantially flat and can be arranged generally opposing one another. The aperture 26 can pass through the body 12 from the first opening to the second opening or from the first side 30 to the opposing second side 32.

[0013] FIG. 3 shows a second part 34 of the suture 10 from where the aperture 26 is located being captured by the snare loop 24. The second part 34 comprises a different portion of the same elongate strand 16 along a different part of the longitudinal length thereof.

[0014] FIG. 4 illustrates the second part 34 of the suture 10 now drawn by the snare loop 24 (FIG. 3) so as to be passed through the aperture 26. Thus, the suture 10 is passed through itself This forms a loop 36 in the suture 10. Optionally, the loop 36 can be maintained and utilized for connection to another suture or for connection to a surgical device or another element, for example. However, FIG. 5 shows the loop 36 of FIG. 4 has be reduced by continuing to pull the second part 34 through the aperture 26 until loop 36 is closed (i.e., substantially eliminated) leaving a surface feature 38 along the surface 14 of the body 12 of the suture 10. This closed loop configuration passes a second portion 40 of the elongate strand 16 that is adjacent the first portion 28 through the aperture 26, thereby creating the surface feature 38. The surface feature 38 can comprise a bump, a ridge, a fold, a proj ection or the like. The surface feature 38 can be thought of as a folded portion of the suture 10 where the second portion 40 is folded over and passed through the first portion 28. The surface feature 38 can occur naturally as the loop 36 closes upon itself. The surface feature 38 can be U-shaped, omega shaped or otherwise shaped and can extend around several sides of the aperture 26. The aperture 26 can remain in some instances and shown in FIG. 4. However, in some cases the surface feature 38 can be large enough to obstruct or partially obstruct/cover the aperture 26 at least along the first side 30 of the suture 10. Indeed, as further discussed herein, an element such as a bead, knot or other mechanism can be utilized to enlarge the surface feature 38 to obstruct or substantially obstruct the aperture 26.

[0015] As discussed previously, the surface feature 38 can create an area of higher friction along the surface 14 of the suture 10 as compared with the remainder of the surface 14 not having the surface feature 38. This surface feature 38, with a higher degree of friction, can be used to better couple with tissue or better couple with the suture itself or other suture like a ratchet mechanism or zip tie, for example.

[0016] FIGS. 6 and 7 show' the methodology described in FIGS. 2-5 repeated on the suture 10 to create a plurality of the surface features 42 (FIG. 7) including the surface feature 38. These plurality of surface features 42 can create a region 44 of relatively higher degree of friction as shown in FIG. 7. This region 44 can have twists or turns of the suture between the plurality of features 42. As shown in FIG. 6, the body 12 can have at least a second aperture 45 therethrough at a third portion 46 of the elongate strand 16. The third portion 46 can be spaced longitudinally along the elongate strand 16 from the second portion 40. A fourth portion 48 of the elongate strand 16 adjacent the third portion 46 can be passed through the second aperture 45 to create at least a second feature along the surface of the body. This second feature is shown as one of the plurality of surface features 42 in FIG. 7.

[0017] FIGS. 8-11 A show examples of various elements that can be captured by the suture using the techniques described above including passing a portion of the suture through an aperture in the suture. The elements contemplated can be anything known in the art for surgical closure that can be passed through or attached to a suture loop. Thus, the elements can include, but are not limited to: a bead(s), a knot(s), and/or a surgical device(s) (e.g., another suture(s), a ring, a hook, a suture anchor or the like).

[0018] FIGS. 8 and 8A show a system 100 according to another example that includes a suture 110 and a bead 112. The suture 110 can be constructed in the manner of the suture 10 previously discussed. FIG. 8 shows the suture 110 punctured in the manner previously described and a portion of the suture 110 passed through an aperture 126 therein. The bead 112 can be placed in a loop 136 formed by passing a portion of the suture 110 through the aperture 126. The bead 112 itself can have a passage or aperture therethrough that allows the suture 110 to pass through the bead 112. The loop 136 can be reduced in size until substantially eliminated in the manner previously described. This results in the suture 110 capturing the bead 112 as shown in FIG. 8A.

[0019] The bead 112 can be shaped to enlarge a surface feature 138 that results from reducing and substantially eliminating the loop 136. The surface feature 138 is shown in FIG. 8A. The increased size of the surface feature 138 that results from capturing the bead 112 can result in an area of increased friction along a surface 114 of the suture 110 relative to other area(s) of the surface 114. As discussed previously, the bead 112 can obstruct or partially obstruct the aperture 126 (FIG. 8).

[0020] Although the bead 112 of FIGS. 8 and 8A is shown as generally spherical in shape, other shapes are contemplated. For example, the bead 112 can have furrows or channels therein along the surface thereof rather than the passage therethrough as illustrate. These channels or furrows can be designed to receive portions of the suture 110. The bead 112 could be disk, flake, block or otherwise shaped if desired to facilitate different shapes for the surface feature 138. [0021] FIGS. 9 and 9A show' a system 200 according to another example that includes a suture 210 and a ring 212. The suture 210 can be constructed in the manner of the suture 10 previously discussed. FIG. 9 shows the suture 210 passed through the ring 212 and punctured in the manner previously described. A portion of the suture 210 can be passed through an aperture 226 therein. The ring 212 can be positioned in a loop 236 formed by passing a portion of the suture 210 through the aperture 226. The loop 236 can be reduced in size until substantially eliminated in the manner previously described. This results in the suture 210 capturing the ring 212 as shown in FIG. 9A. [0022] The ring 212 can be shaped to provide a linkage whereby other surgical devices such as additional sutures, etc. can be coupled to the suture 210. The ring 212 can additionally enlarge a surface feature 238 that results from reducing and substantially eliminating the loop 236. The surface feature 238 is shown in FIG. 9A, The ring 212 can obstruct or partially obstruct the aperture 226 (FIG. 9).

[0023] FIGS. 10 and 10A show a system 300 according to another example that includes a first suture 310 and a second suture 312. The first suture 310 and/or the second suture 312 can be constructed in the manner of the suture 10 previously discussed. The first suture 310 can have a same or different construction relative to one another. FIG. 10 shows the first suture 310 punctured in the manner previously described and a portion of the first suture 310 passed through an aperture 326 therein. The second suture 312 can be placed in a loop 336 formed by passing a portion of the first suture 310 through the aperture 326. The loop 336 can be reduced in size until substantially eliminated in the manner previously described. This results in the first suture 310 capturing the second suture 312 as shown in FIG. 10A

[0024] The second suture 312 can provide an additional linkage to soft tissue and/or another surgical device such as an anchor. The second suture 312 can be provided with surface features such as those discussed herein (e.g,, knots, loops, beads, etc.), which can help prevent the second suture 312 from slipping in the loop 336. The second suture 312 can additionally enlarge a surface feature 338 of the first suture 310 that results from reducing and substantially eliminating the loop 336. The surface feature 338 is shown in FIG. IGA. The second suture 312 can obstruct or partially obstruct the aperture 326 (FIG. 9) of the first suture 310.

[0025] FIGS. 11 and 11A show a suture 410 according to another example. The suture 410 can be constructed in the manner of the suture 10 previously discussed save that the suture 410 can include a knot 412 therein. FIG. 11 shows the suture 410 punctured in the manner previously described and a portion of the suture 410 passed through an aperture 426 therein. The knot 412 can be positioned so as to be placed in and form part of a loop 236 formed by passing a portion of the suture 410 through the aperture 426. The loop 436 can be reduced in size until substantially eliminated in the manner previously described. This results in the suture 410 folded over, capturing or otherwise positioning the knot 412 at or adjacent the aperture 426 as shown in FIG. 11 A.

[0026] The knot 412 can be shaped in any manner known in the art. Thus, the shape of the knot is purely exemplar}'. The knot 412 can enlarge a surface feature 438 that results from reducing and substantially eliminating the loop 436. The surface feature 438 is shown in FIG. 11 A, The increased size of the surface feature 438 that results from capturing, folding over or otherwise utilizing the knot 412 as part of the closed loop construct can result in an area of increased friction along a surface 414 of the suture 410 relative to other area(s) of the surface 414. As discussed previously, the knot 412 can obstruct or partially obstruct the aperture 426 (FIG. 11). [0027] FIG. 12 shows a flowchart for a surgical or manufacturing method 500 in accordance with at least one example of the present disclosure. The method 500 can be utilized in a surgical procedure that utilizes various suture constructs, such as the suture constructs shown and described with respect to FIGS. 2-11 A herein. However, the method 500 can also be used to fabricate OEM suture that can be sold and then utilized in a surgical procedure. The method 500 can include the step of puncturing 502 an elongate body of a suture to form an aperture. The method 500 can include passing 504 a portion of the elongate body through the aperture so as to form part of the elongate body into a loop. The passing the second portion of the elongate body through the aperture so as to form the elongate body into the loop can include capturing the suture in a snare loop that is passed through the aperture. The surgical method 500 can include reducing 506 the loop to form a ridge along a surface of the body adjacent the aperture.

[0028] The method 500 can optionally include creating a knot in the elongate body and capturing the knot within the loop with the reducing the loop. The method can include capturing an element within the loop with the reducing of the loop as previously described an illustrated. As discussed the element can comprise at least one of a knot, a bead, a surgical device or a second suture.

[0029] The various stages of method 500 have been described in a particular order for ease of discussion and completeness. However, the various stages of method 500 can be rearranged and/or omitted without departing from the scope of the present disclosure. The suture constructs and surgical methods disclosed herein can be modified without departing from the scope of the present disclosure.
