Abstract

Improved breast prostheses, methods of making breast prostheses, and methods of treatment using such breast prostheses are described.

Claims

1. A method of making a prosthesis, comprising:

providing one or more samples of graft material and a breast implant or tissue expander, the graft material including suture tabs attached thereto;

forming a pocket sized and shaped to hold the breast implant or tissue expander from the graft material; and

inserting the breast implant or tissue expander into the pocket.

2. The method of claim 1, wherein forming the pocket comprises cutting a slit into the graft material.

3. The method of claim 1, further comprising cutting the graft material to form at least two pieces of graft material.

4. The method of claim 3, wherein forming the pocket comprises attaching the at least two pieces of graft material to one another with an adhesive or sutures.

5. The method of claim 1, wherein the one or more samples of graft material comprise acellular tissue matrix.

6. The method of claim 1, wherein the one or more samples of graft material comprise adipose tissue matrix.

7. A prosthesis for the treatment of breast tissue, comprising:

a breast implant or tissue expander;

one or more pieces of graft material comprising a pocket sized and shaped to hold a breast implant or tissue expander; and

one or more suture tabs extending from the one or more samples of graft material, the one or more suture tabs configured to attach to tissue.

8. The prosthesis of claim 7, wherein the pocket comprises a slit in a piece of graft material.

9. The prosthesis of claim 7, wherein the pocket is formed from two pieces of graft material attached to one another with an adhesive or sutures.

10. The prosthesis of claim 7, wherein the one or more suture tabs are configured to attach to tissue in a chest wall of a patient.

11. The prosthesis of claim 7, wherein the one or more pieces of graft material comprise acellular tissue matrix.

12. The prosthesis of claim 7, wherein the one or more pieces of graft material comprise adipose tissue matrix.

13. A method of treatment, comprising:

providing a prosthesis comprising;

a breast implant or tissue expander;

one or more samples of graft material comprising a pocket sized and shaped to hold a breast implant or tissue expander; and

one or more suture tabs extending from the one or more samples of graft material, the one or more suture tabs configured to attach to tissue;

inserting the breast implant or tissue expander into the pocket; and

attaching the one or more suture tabs to a chest wall of a patient to secure the prosthesis.

14. The method of claim 13, wherein the breast implant or tissue expander is inserted into the pocket prior to implanting the prosthesis.

15. The method of claim 13, wherein the one or more suture tabs are attached to the chest wall followed by inserting the breast implant or tissue expander into the pocket.

16. The method of claim 13, wherein the one or more samples of graft material comprise acellular tissue matrix.

17. The method of claim 13, wherein the one or more samples of graft material comprise adipose tissue matrix.

18. The method of claim 13, wherein the graft material comprises acellular dermal tissue matrix.
