Abstract

Methods, systems, and compositions for treatment are provided. The methods can be used to stretch and completely or nearly completely wrap a composition around an implant or tissue expander. The systems can be used to protect an implant or tissue expander by completely or nearly completely wrapping a composition around the implant or tissue expander. The compositions can be used to completely or nearly completely wrap around an implant or tissue expander to provide support and protection to the implant or tissue expander.

First claim

What is claimed is:

1 . A method of treatment, comprising:
providing a composition, the composition including (i) a tissue matrix or synthetic material defining a composition body, and (ii) a mesh pattern formed in at least a portion of the composition body; and stretching and expanding the composition body at the mesh pattern to completely or nearly completely wrap the composition around or position the composition onto an implant or a tissue expander.

2 . The method of claim 1 , wherein the tissue matrix is a tissue matrix sheet defining a planar and flexible configuration.

3 . The method of claim 1 , wherein the tissue matrix is an acellular tissue matrix.

4 . The method of claim 1 , wherein the composition comprises a central region and four extensions extending from the central region.

5 . The method of claim 4 , comprising forming the mesh pattern in at least one of the four extensions.

6 . The method of claim 4 , comprising forming the mesh pattern in the central region.

7 . The method of claim 4 , comprising interlocking two of the four extensions of the composition with a fastening element.

8 . The method of claim 1 , wherein the composition comprises a top region, a central region, and a bottom region.

9 . The method of claim 8 , comprising at least one strap integrally formed adjacent to an edge of the bottom region.

10 . The method of claim 9 , comprising stretching the at least one strap around a portion of the implant or tissue expander to maintain the composition in a wrapped configuration.

11 . The method of claim 1 , wherein the composition comprises two flaps extending from one edge of the composition body, and the method comprises passing the two flaps through slits of the mesh pattern to maintain the composition completely or nearly completely wrapped around the implant or tissue expander.

12 . The method of claim 1 , wherein the composition comprises a first composition half and a second composition half, wherein the first composition half comprises two flaps extending from a top edge and two flaps extending from a bottom edge, and the method comprises passing the two flaps extending from the top edge of the first composition half into slits of the mesh pattern of one edge of the second composition half, and passing the two flaps extending from the bottom edge of the first composition half into slits of the mesh pattern of an opposing edge of the second composition half, to maintain the composition completely or nearly completely wrapped around the implant or tissue expander.

13 . A composition for treatment, comprising:
a composition body; and a mesh pattern formed in at least a portion of the composition body; wherein the composition body comprises a tissue matrix or synthetic material; and wherein the composition body is configured to stretch and expand at the mesh pattern to completely or nearly completely wrap the composition body around or position the composition body onto an implant or a tissue expander.

14 . The composition of claim 13 , wherein the tissue matrix is an acellular tissue matrix.

15 . The composition of claim 13 , wherein the composition body comprises a central region and four extensions extending from the central region, at least one of the four extensions comprising the mesh pattern formed therein.

16 . The composition of claim 15 , comprising a fastening element configured to interlock at least two of the four extensions relative to each other.

17 . The composition of claim 13 , wherein the composition body comprises a top region, a central region, and a bottom region, at least one strap being integrally formed adjacent to an edge of the bottom region.

18 . The composition of claim 1 , wherein the composition body comprises two flaps extending from one edge of the composition body, and wherein the two flaps are configured to pass through slits of the mesh pattern to maintain the composition body completely or nearly completely wrapped around the implant or tissue expander.

19 . The composition of claim 1 , wherein the composition body comprises a first composition half and a second composition half, and wherein the first composition half comprises two flaps extending from a top edge and two flaps extending from a bottom edge.

20 . A system for treatment, comprising:
a composition, the composition including (i) a tissue matrix or synthetic material defining a composition body, and (ii) a mesh pattern formed in at least a portion of the composition body; and an implant or a tissue expander; wherein the composition body is configured to stretch and expand at the mesh pattern to completely or nearly completely wrap the composition body around or position the composition body onto the implant or the tissue expander.
