The method may include making an incision at the desired site of a subject. For example, for a nipple prosthetic, the site may be at a location of areola/areola tattoo on a reconstructed breast.

(0082) After making an incision, the base member 110 of a dermal implant may be inserted into the incision of the skin so that (i) the base may be disposed underneath the skin and (ii) a portion of the post 140 partially may be exposed and accessible through the incision site. Next, the securing member 150 may be moved along the post 140 of the base member 110 towards the base 120 so that the one or more arms 136 of the securing member 130 engages the complimentary opening(s) 112 and is in the secured state.

(0083) In some embodiments, the method may use an instrument, such as the securing instrument 170. For example, if using the securing instrument 170, after the placement of the base member 110, the securing instrument 170 may engage the securing member 150 to move the securing member along the post 140 of the base member 110 towards the base 120 while the arms 178 of the securing instrument 170 radially expand to engage the tissue surrounding the incision. [0084] In some embodiments, the arms 160 may be disposed on the securing member 150 so that the instrument 170 moves both the arms 160 and the securing member 150 towards the base 120. In this example, the securing instrument 170 may move the securing member 150 until the one or more arms 160 engage the complimentary set of opening(s) 132 of the base 120.

[0085] In another example, the securing instrument 170 may be used to move only the securing member 150 with respect to the post 140. After the securing member 150 is secured to the post 140, the arms 180 may be attached (mechanically or magnetically) to the securing member 150 and/or the complimentary set of openings 132 of the base 120.

[0080] After the securing member 150 is in the secured state, the instrument 170 may be removed. The attachment member (e.g., 190) may then be removably attached to the post 140. For example, the attachment member 190 may be removably attached so as to cover the opening 142 of the post 140, as shown in Figure 1. It will be understood that the arms 160 and the securing member 150 are not shown in Figure 1.

[0087] For example, the attachment member 190 may be configured to be screwed into the post 120. In this example, the attachment member 190 may have threads complimentary to threads providing along the internal surface of the opening 142 of the post 140. After the attachment member 190 is secured, the external object may be attached, for example, using a complimentary mechanism (e.g., magnetic and/or mechanical) to the attachment member 190. The user (e.g., subject, patient, etc.) may be capable of removing the object from the attachment member 190, replacing the object with a different object, among others, or any combination thereof.

[ 8 j In some embodiments, the obj ect and/or the attachment member 190 may be configured to exert nonuniform pressure. For example, the object and/or the attachment member 190 may be configured to have nonuniform weight and/or engage the one or more arms to adjust the pressure on the surrounding tissue. In some examples, the system may include more than one object and/or attachment member 190. For example each obj ect/ attachment member may be configured to exert different pressures.

[0089] It will be understood that the implant 100 may be delivered with a different instrument and is not limited to the securing instrument 150 shown and described. [ 090] Figures 6 and 7 show additional examples of base members having two set of openings. Figure 6 shows an example of a base member 610. Like the base member 110, the base member 610 may include a base 620 and a post 640 disposed so as to extend from the base 620. Like the base member 110, the base member 620 may include openings 636 disposed along the length. Like the base member 110, the post 640 may include an opening 642 to a channel that is extends at least partially along the length of the post 640.

In this example, each set of openings 632 may include a first opening 631 disposed on the top surface 625 of the base 620 and a second opening 633 disposed on the side surface 626 of the base 620, and a channel therebetween. Each set of openings 632 may be configured to form a curved channel disposed on one side of the base 620.

[9092] Figure 7 shows an example of a base member 710. Like the base members 110 and 610, the base member 710 may include a base 720 and a post 740 disposed so as to extend from the base 720. Like the base members 110 and 610, the base member 720 may include openings 736 disposed along the length. In this example, the post 740 may be solid. In some embodiments, the post 740 may include an opening to a channel like posts 140 and 640.

[9093] In some embodiments, like the base member 610, the base member 710 may include two sets of openings 732. In this example, each set of openings 732 may include a first opening 731 disposed on the side surface 726 adjacent to the top surface of the base 720 and a second opening 733 disposed on the side surface 726 adjacent to the bottom surface of the base 720, and a channel therebetween. Each set of openings 732 may be configured to form a channel that traverses opposite sides of the base 720.

[9994 j Figures 8A-13B show another example of a dermal implant system. In some embodiments, the dermal implant system may include a dermal implant 800 as shown in Figures 8A-11.

[9995] In some embodiments, the dermal implant 800 may include a base member (also referred to as “anchor”) 810, securing member(s), and one or more arms (also referred to as “tines”) 860.

[0096] In some embodiments, like the base members 110, 610, and 710, the base member 810 may include a base 820 and a post 840 that extends from the base 810. The base 820 may be an elongated plate having a first end 821, a second end 823, and a length therebetween. The base 820 may include a top (first) surface 825, a bottom (second) surface, and a side surface 826 disposed therebetween. In some embodiments, the base 820 may have a tapered height of the side surface 826 (between the top surface 825 and the bottom surface) along its length so that the height of the side surface 826 at the first end 821 is higher than the height of the side surface 826 at the second end 823.

(0097) In some embodiments, the base 820 may have any shape. For example, the base 820 may have an elongated shape with rounded and/or square ends, a rounded shape, a square shape, a different shape, among others, or any combination thereof.

In this example, each set of openings 832 may include two openings. In some embodiments, each set of openings 832 may form a channel in the base 820. In this example, the base member 810 may include two sets of openings 832. In some embodiments, the base member 810 may include more or less sets of openings 832.

[0099) In some embodiments, each set of openings 832 may include a first opening 831 disposed on the top (first) surface 825 of the post 820 on one side of the post 840, a second opening

833 disposed on the side surface 826 of the base 820 on a different side of the post 840, and a channel disposed there between, as shown in Figures 8A-9. As shown, the first opening 835 of the second set may be disposed above the second opening 833 of the first set one side, and the first opening 833 of the first set may be disposed above the second opening of the second set on the opposing side. This way, the channels defined by the sets of openings 832 may traverse each other and extend through opposite sides of the base 820.

{06190) In some embodiments, each set of openings 832/channels may be configured to receive an arm. In some embodiments, the first opening 831, 835 of each set may be shaped so as to be complimentary to a shape of the corresponding end of the arm 860 so that the arm 860 can be (removably) securely attached to the base 820. In this example, each first opening may have a rectangular shape. For example, each arm 860 may be (removably) securely attached to the base 820 when inserted into a respective first opening and slide through until the end of the arm 860 mates with that first opening. (00101] In some embodiments, the base member 810 may include one or more holes 836 disposed along the length of the base 820. The one or more holes 836 may have a rounded shape. In some embodiments, the one or more holes 836 may have the same circumference or perimeter. In some embodiments, the one or more holes 836 may have each have a different circumference or perimeter. The holes 836 may be configured to allow tissue healing to bridge through the holes 836 of the base 120, thereby improving the retention and stability of the device 800 after the base implantation. In some embodiments, each of the holes 836 may also have sharp edges around the respective circumference. These sharp edges may be configured to cut the derma when the base member is removed.

(60162] In some embodiments, the post 840 may be disposed on the base 820 and extending perpendicular to the length of the base 820. The post 840 may be disposed so as to extend from the top surface 825 of the base 820. In some embodiments, the post 840 may be disposed on the base 820 between the one or more sets of openings 832 and the one or more holes 836.

( 01 31 In some embodiments, the post 840 may include a first end 841, a second end 843, and a length therebetween. The second end 843 of the post 840 may be disposed on the top surface 825 of the base 820. In some embodiments, the post 840 may include an opening 842 to a channel 844 that is extends at least partially along the length of the post 840. In some embodiments, the post 840 may include threads 846 disposed along at least a portion of the channel 844.

The second portion 864 may have an elongated, flattened shape and sized/shaped to be disposed and inserted within each channel of each set of openings 832. In some embodiments, the third portion 866 may have a tapered shape that the ends with a tip at the second end 863. In some embodiments, the tip may be straight. In some embodiments, the tip may be pointed. In some embodiments, the first portion 862 may protrude from the second portion 864 and third portion 864.

(00116J In some embodiments, each arm 860 may be made of one or more biocompatible and MRI compatible materials.. In some embodiments, the first portion 862, the second portion 864, and the third portion 866 may be integrally formed of the one or more materials. For example, each arm 860 may be made of one or more MRI compatible metals.

{061171 In some embodiments, the second portion 864 and the third portion 866 may have a different shape. For example, the second portion 864 may be a rigid wire and the third portion 866 may have a coil/spring shape. This way, any discomfort from the breast being squeezed around the base member 820 can be prevented.

{001181 In some embodiments, the device 100 may include the securing member 850 configured to be removably disposed on the post 840. When disposed on the post 840, the securing member 850 may be configured to clamp against the top surface of the base 820 and the one or more arms 860 thereby preventing the arm(s) 860 from moving. In some embodiments, the securing member 850 may be a cap configured to couple to the post 840.

(60119J As shown in Figures 10A and 10B, the securing member 850 may have a body including a first end 851, a second end 853, and a length therebetween. In some embodiments, the securing member 850 may include a channel 855 disposed at least along a length of the securing member 850.

(601231 In some embodiments, the first portion 856 and the second portion 858 may be of different sizes and/or shapes. For example, the first portion 856 may have a square shape and the second portion 858 may have a rounded shape. In some embodiments, the first port portion 856 may have a smaller diameter/perimeter than the second portion 858. In some embodiments, the first portion 856 and the second portion 858 may have a different shape and/or size.

(60124] In some embodiments, the system may include additional and/or alternative securing members. For example, the system may include an additional securing member that has a smaller height so as to be disposed within the skin so as not to protrude through the incision site. (001251 In some embodiments, the base 820 and the post 840 may be made of one or more biocompatible and MRI compatible materials. For example, the one or more materials may include but is not limited to titanium alloy, such as Ti-64 (Ti-6A1-4V).

[001261 Figures 12 and 13A-B show examples of instruments 1200 and 1300 that can be used with the dermal implant 800 according to embodiments. In some embodiments, the system may include the instruments 1200 and 1300. In some embodiments, the system may include additional and/or alternative instruments.

[0012?! Figure 12 shows the instrument 1200 that can be configured to removably hold the base member 810 so that the base member 810 can be implanted within an incision site according to embodiments. As shown, the instrument 1200 may have a first end 1201, a second end 1203, and a length therebetween. In some embodiments, the instrument 810 may be an elongated rod with a tapered tip portion 1210. In some embodiments, the instrument 1200 may include an engaging member 1220 disposed at the second end 1203 (tip of the tapered tip portion 1210). The engaging member 1220 may be configured to engage the post 840. By way of example, the engaging member 1220 may include threads that are complimentary to the threads 846.

[00128] Figures 13 A and B show the instrument 1300 that can be configured to removably hold each arm 860 so that it can be delivered to each set of openings 832. For example, the instrument 1300 may be a hinged, locking clamp instrument. For example, the instrument 1300 may include a pair of sections (also referred to as “jaws”) 1310 that are pivotally adjoined by a pin 1330 in a scissor-like configuration to allow a user to place and secure each arm within the base member 810. Each section 1310 may include a first end 1310, a second end 1313, and a length therebetween 1311. In some embodiments, each section 1310 may include a ring handle 1320. [001291 In some embodiments, each section 1310 may include one or more engaging members

1350 configured to engage the one or more engaging members 865 of each arm 860. The one or more engaging members 1350 may be complimentary to the one or more engaging members 865 of each arm 860. In some embodiments, the total number of engaging members 1350 may correspond to the number of engaging members 865. For example, in this example, the instrument 1300 may include two engaging members 1350. Each section 1310 may include one engaging member 1350 on the inner surface at the first end 1310.

[00130] In some embodiments, each engaging member 1350 may be a protruding member that corresponds to the respective opening 865. In this example, each engaging member 1350 may be of the same size and shape. In some embodiments, the engaging members 1350 may be of different size, different shape, among others, or any combination thereof.

|00I31| In some embodiments, the members 1310 may be the same and connected by the pin 1330 so as to be symmetric. In some embodiments, the members 1310 may be of different size, may be of different shape, may be connected by the pin 1330 so as to be asymmetric, among others, or any combination thereof.

[00132] In some embodiments, the instrument 1300 may include a locking member 1340 that may be connected to the members 1310 and can be configured to removably lock the members 1310 in position. In some embodiments, the locking member 1340 may be a ratchet.

[ 0133] Figures 14-22 show an example of a procedure for inserting the device 800 using the instruments 1200 and 1300 into an incision site so that an external object can be attached. In this example, the procedure may be implanting the device 800 in an incision site of a breast of a subject so that an external object, such as a nipple prosthetic as shown, may be attached.

[00134] As shown in Figure 14, a user (e.g., medical professional) may use the instrument 1200 may be removably attached to the base member 810, for example, by screwing the engaging member 1220 into the channel 844 of the post 840 so that the engaging member 1220 engages the complimentary threads 846. After the instrument 1200 is attached to the base member 810, the user may position the base member 810 within an incision site in the breast using the instrument 1200. As shown in Figure 15, the base member 810 may be positioned so that the post 840/the instrument 1200 is disposed within and extending from an incision site 1512 and the base 820 is disposed under the skin 1511 ofabreast 1510. It will be understood that the breast/skin 1510/1511 and associated dermis is illustrated as a box in the figures for illustrated purposes.

[00135) Once the base member 810 is properly inserted into the incision site 1510, as shown in Figure 15, the user may insert the arms 860 into the base member 810, for example, using the instrument 1300. To prepare an arm 860 for placement, the user may position the sections 1310 of the instrument 1300 so that each engaging members 1350 interfaces with the engaging members 865 of the arm 860. In this example, the engaging members 1350, 865 interface when each engaging member 1350 is mated with the respective engaging member 865. Figure 16 shows the instrument 1300 being moved from an open position to a closed position so that the each engaging member 1350 is mated with the respective engaging member 865. In this figure, the arm 860 is illustrated as transparent for illustrative purposes. After the engaging members are mated as shown in Figures 17A and 17B, the instrument may be locked into position with the locking member 1340.

[0006] Once the arm 860 is secured in the instrument 1300, the user may move the base member 810 using the instrument 1200 to provide access to the respective opening 832 within the incision site 1512. For example, the user may move the instrument 1300 toward the side opposite of the respective opening 832 as shown in Figure 17A. The user may insert the arm 860 so that the first portion 862 abuts against the respective first opening 831, 835. After one arm 860 is disposed in one of the openings 832 so it abuts against the respective first opening, the user may move the base member 810 towards to the other side so that the other arm 860 may be disposed in the other opening 832 so that the respective first portion 862 abuts against that first opening. (001371 Figure 18 shows a view of the arms 860 being securely positioned in the base member 810 and in the incision site 1512. As shown, the post 840 can be accessible via the incision site 1512. A user may now attach a securing member to the post 840. In some embodiments, the securing member 850 may be attached to the post 840 by screwing the member 850 onto the post 840 as shown in Figure 18 and 19. As shown in Figure 19, the securing member 850 may be disposed so as to be accessible via the incision site 1512.

[0008] In some embodiments, a different securing member may be attached to the post 840. For example, before the securing member 850 is attached, an additional securing member may be attached to the post 840 by engaging its coupling member with the complimentary threads 846 disposed in the inner channel 842 of the post 8410. The additional securing member may have a profile (height) that is lower than the securing member 850. When the attached to the post 840, the additional securing member may be disposed so as to lie under the skin. This additional securing member can be attached for a period of time to allow the incision site to heal forming a capsule of dense scar/fibrotic tissue to form around the base member 820 and the arms 860 under sterile conditions. This fibrotic capsule can protect the reconstructed breast from, for example, infection. After that period of time, the additional securing member can be removed and the securing member 850 may be attached the post 840 by twisting the securing member 850 so that the threads of the coupling member 857 engages the threads 846 of the post 840.

(00139] After the securing member 850 is attached to the post 840 as shown in Figure 19, an external object may be attached to the device 800. As shown, the securing member 850 may be configured to accessible through the incision site 1512 when attached to the post 840. In the example shown in Figures 21 and 22, the external object may be a nipple prosthetic 2110 including an attachment member that is magnetic and complimentary to the attachment member 890. Figure 22 shows the nipple prosthetic 2110 securely attached to the attachment member 890. With the device 800 implanted as shown in Figure 19, the subject (e.g., patient) can be attach and remove the nipple prosthetic 2110 as needed, as well as remove and replace the prosthetic 2110 with other external objects.

[00140] In some embodiments, the implant device (e.g., device 100 and/or 800) and/or system may be part of a kit.
