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