Abstract

Graft materials and devices for surgical breast procedures, as well as methods of making graft devices, are described.

First claim

What is claimed is:

1. A medical implant, comprising:
a breast implant; and
a sample of biocompatible material configured and dimensioned to conform to at least a portion of the breast implant and comprising a first edge consisting essentially of a first convex portion and a second edge consisting essentially of a second convex portion;
wherein, when the sample of biocompatible material is in a planar configuration, the first convex portion of the first edge defines a first radius of curvature that extends away from the second edge and the second convex portion of the second edge defines a second radius of curvature that extends away from the first edge, the first radius of curvature being different from the second radius of curvature; and
wherein the first and second edges of the sample of biocompatible material are joined to each other at pointed apexes.

2. The medical implant of claim 1 , wherein the sample of biocompatible material is sheet-like in form.

3. The medical implant of claim 1 , wherein the sample of biocompatible material comprises a single layer sheet.

4. The medical implant of claim 1 , wherein the sample of biocompatible material comprises a multi-layered sheet.

5. The medical implant of claim 1 , wherein the first edge includes a straight portion.

6. The medical implant of claim 1 , wherein the second edge includes a straight portion.

7. The medical implant of claim 1 , wherein the sample of biocompatible material is oversized relative to the breast implant.

8. The medical implant of claim 1 , wherein the sample of biocompatible material comprises an acellular tissue matrix.

9. The medical implant of claim 8 , wherein the acellular tissue matrix comprises a decellularized collagen-containing tissue matrix from a nonhuman animal.

10. The medical implant of claim 9 , wherein the nonhuman animal is a pig.

11. The medical implant of claim 9 , wherein the nonhuman animal is genetically modified such that tissues in the nonhuman animal lack galactose α-1,3-galactose epitopes.

12. The medical implant of claim 8 , wherein the acellular tissue matrix lacks an epithelial basement membrane.

13. The medical implant of claim 8 , wherein the acellular tissue matrix is a dermal tissue matrix.
