Abstract

Graft materials and devices for surgical breast procedures may include a sheet of biocompatible material and a plurality of fenestrations distributed across a portion of the sheet of biocompatible material. The sheet of biocompatible material can have a first axis and a second axis coincident with the sheet of biocompatible material. The sheet of biocompatible material can also have a first edge that intersects the second axis and a second edge that intersects the second axis. The first axis can be orthogonal to the second axis. The plurality of fenestrations can be distributed across a portion of the sheet of biocompatible material closer to the first edge than the second edge. Other apparatuses and methods are disclosed.

Claims

1. A graft for surgical procedures, comprising:

a sheet of biocompatible material having a first axis coincident with the sheet of biocompatible material, a second axis coincident with the sheet of biocompatible material, a first edge that intersects with the second axis, and a second edge that intersects with the second axis, wherein the first axis is orthogonal to the second axis and a length of the sheet of biocompatible material along the first axis is longer than a length of the sheet of biocompatible material along the second axis; and

a plurality of fenestrations distributed across a portion of the sheet of biocompatible material, wherein at least a portion of the plurality of fenestrations are arranged in a plurality of rows, wherein each row is parallel to the first edge, each fenestration of the plurality of fenestrations is parallel to the first edge, and at least one of the first edge and second edge has a convex curvature.

2. The graft of claim 1, wherein the plurality of fenestrations comprises:

a first row of fenestrations having a first length; and

a second row of fenestrations having a second length;

wherein the second length is greater than the first length.

3. The graft of claim 1, wherein the plurality of fenestrations comprises:

a first row of fenestrations; and

a second row of fenestrations;

wherein the first row of fenestrations includes a greater number of fenestrations than the second row of fenestrations.

4. The graft of claim 1, wherein the plurality of fenestrations comprises:

a first row of fenestrations; and

a second row of fenestrations;

wherein the fenestrations of the first row of fenestrations are offset from the fenestrations of the second row of fenestrations.

5. A graft material, comprising:

a sheet comprising a biocompatible material configured to conform to a portion of a breast implant, the sheet further comprising a first edge and a second edge, wherein at least one of the first edge and the second edge is curved;

a first set of perforations through a first portion of the biocompatible material; and

a second set of perforations through a second portion of the biocompatible material;

wherein at least one of the first set of perforations and the second set of perforations is parallel to the first edge of the sheet, and

wherein each perforation of the first set of perforations and the second set of perforations is parallel to the first edge of the sheet.

6. The graft material of claim 5, wherein the first portion of the sheet of biocompatible material is an upper portion of the sheet of biocompatible material and the second portion of the sheet of the biocompatible material is a lower portion of the sheet of the biocompatible material.

7. The graft material of claim 5, wherein the first set of perforations comprises a first group of slits of a first length and the second set of perforations comprises a second group of slits of a second length.

8. The graft material of claim 7, wherein the second length is greater than the first length.

9. The graft material of claim 5, wherein a first distance between perforations of the first set of perforations is greater than a second distance between perforations of the second set of perforations.

10. The graft material of claim 5, wherein the first set of perforations are offset from the second set of perforations.

11. The graft material of claim 5, wherein the first set of perforations comprises perforations that are linear.

12. A medical implant, comprising:

a sheet of biocompatible material configured to conform to at least a portion of a breast implant, wherein the sheet comprises a first edge and a second edge, and wherein at least one of the first edge and the second edge has a convex curvature; and

a set of perforations positioned on the sheet of biocompatible material, wherein the set of perforations comprises;

a first row of slits, and

a second row of slits,

wherein each slit of the first row of slits and the second row of slits is parallel to the first edge, and

wherein slits of the first row of slits are offset from slits of the second row of slits.

13. The medical implant of claim 12, further comprising a first breast implant.

14. The medical implant of claim 12, further comprising a first breast implant, and wherein the set of perforations is adapted to permit expansion of portions of the sheet of biocompatible material around a surface of the first breast implant.

15. The medical implant of claim 12, wherein the first row of slits is separated from the second row of slits by a uniform separation distance.

16. The medical implant of claim 15, wherein the uniform separation distance is between 0.1 millimeters and 20 millimeters.

17. The medical implant of claim 16, wherein the uniform separation distance is between 2 millimeters and 6 millimeters.

18. The medical implant of claim 12, wherein the slits of the first row of slits have a uniform length of between 0.1 millimeters and 20 millimeters.

19. The medical implant of claim 18, wherein the uniform length is between 4 millimeters and 8 millimeters.
