Abstract

The present disclosure provides devices and methods for treating the breast. The devices can include an acellular tissue matrix having a predefined shape. The shape can include a first edge with an S-shaped configuration and a second arcuate-shaped edge. The shape alternatively can include a first concave edge and a second convex edge.

Claims

1. A breast treatment device, comprising:

a sheet of acellular tissue matrix, wherein the sheet of acellular tissue matrix comprises;

a first end;

a second end opposite the first end, the first end and the second end being differently shaped;

a first edge extending from the first end to the second end and consisting of an S-shaped curve having a concave section positioned between a first convex section and a second convex section, and

a second edge extending from the first end to the second end and consisting of a third convex section;

wherein the first edge and the second edge meet at the first end and the second end.

2. The device of claim 1, wherein the first end of the device comprises a first pointed tip.

3. The device claim 2, wherein the second end of the device comprises a second pointed tip.

4. The device of claim 1, wherein the second end of the device comprises a rounded edge.

5. The device of claim 1, wherein the tissue matrix comprises a tissue matrix derived from a human tissue.

6. The device of claim 1, wherein the tissue matrix comprises a tissue matrix derived from porcine tissue.

7. The device of claim 1, wherein the tissue matrix comprises a dermal tissue matrix.

8. The device of claim 7, wherein the dermal tissue matrix further comprises an epithelial basement membrane on the top surface of the tissue matrix.

9. A method of treating a breast, comprising:

identifying an anatomic site within a breast;

selecting a breast treatment device comprising a sheet of acellular tissue matrix, wherein the sheet of acellular tissue matrix comprises a flexible sheet having a top surface, a bottom surface, a first end, a second end opposite the first end and being differently shaped, and a peripheral border, and wherein the peripheral border comprises a first edge extending from the first end to the second end and consisting of an having a S-shaped curve having a concave section positioned between a first convex section and a second convex section, and an arcuate-shaped second edge extending from the first end to the second end; and

implanting the treatment device in or proximate the breast; and

securing at least a portion of the treatment device along the second arcuate-shaped edge to tissue in or near the breast.

10. The method of claim 9, further comprising implanting a breast implant or tissue expander within the breast.

11. The method of claim 10, wherein the breast implant or tissue expander comprises a silicone or saline filled implant or tissue expander.

12. The method of claim 9, wherein the treatment device is implanted with the arcuate-shaped second edge facing inferiorly.

13. The method of claim 9, wherein the tissue matrix comprises a tissue matrix derived from a human tissue.

14. The method of claim 9, wherein the tissue matrix comprises a tissue matrix derived from porcine tissue.

15. The method of claim 9, wherein the tissue matrix comprises a dermal tissue matrix.

16. The method of claim 15, wherein the dermal tissue matrix further comprises an epithelial basement membrane on the top surface of the tissue matrix.

17. The method of claim 15, wherein the treatment device is implanted with the top surface facing towards a chest wall of a patient in which the treatment device is implanted.

18. A breast treatment system, comprising:

a breast implant or tissue expander; and

a sheet of acellular tissue matrix, wherein the sheet of acellular tissue matrix comprises a flexible sheet with a top surface, a bottom surface, a first end, a second end opposite the first end, and a peripheral border, and wherein the peripheral border comprises a first edge extending from the first end to the second end and consisting of an S-shaped curve having a concave section positioned between a first convex section and a second convex section, and a second edge extending from the first end to the second end and consisting of a third convex section;

wherein the first edge and the second edge meet at the first end and the second end, and the first end and the second end are differently shaped.

19. The breast treatment system of claim 18, wherein the first end of the sheet of acellular tissue matrix comprises a first pointed tip.

20. The breast treatment system claim 19, wherein the second end of the sheet of acellular tissue matrix comprises a second pointed tip.

21. The breast treatment system of claim 18, wherein the second end of the sheet of acellular tissue matrix comprises a rounded edge.

22. The breast treatment system of claim 18, wherein the tissue matrix comprises a tissue matrix derived from a human tissue.

23. The breast treatment system of claim 18, wherein the tissue matrix comprises a tissue matrix derived from porcine tissue.

24. The breast treatment system of claim 18, wherein the tissue matrix comprises a dermal tissue matrix.

25. The breast treatment system of claim 24, wherein the dermal tissue matrix further comprises an epithelial basement membrane on the top surface of the tissue matrix.

26. A breast treatment device, comprising:

a sheet of acellular tissue matrix, wherein the sheet of acellular tissue matrix comprises a flexible sheet with a top surface, a bottom surface, a first end, a second end opposite the first end and being differently shaped, and a peripheral border, and wherein the peripheral border consists of a first edge and a second edge that meet at the first end of the device and at the second end of the device;

wherein the first edge extends from the first end to the second end and consists of an S-shaped curve having a concave section positioned between a first convex section and a second convex section;

wherein the first end of the device comprises a pointed tip, and the second end of the device comprises a rounded edge, the pointed tip and the rounded edge being differently shaped.

27. The device of claim 26, wherein the tissue matrix comprises a tissue matrix derived from a human tissue.

28. The device of claim 26, wherein the tissue matrix comprises a tissue matrix derived from porcine tissue.

29. The device of claim 26, wherein the tissue matrix comprises a dermal tissue matrix.

30. The device of claim 29, wherein the dermal tissue matrix further comprises an epithelial basement membrane on the top surface of the tissue matrix.
