Abstract

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

Claims (29)

1. A prosthesis comprising a tissue expander and one or more samples of graft material, wherein the tissue expander comprises resorbable tabs and the one or more samples of graft material comprise apertures, and wherein the one or more samples of graft material are attached to the tissue expander by engaging the resorbable tabs on the tissue expander to the apertures on the one or more samples of graft material.

2. A method of making an implantable prosthesis comprising providing a tissue expander and one or more samples of graft material, wherein the tissue expander comprises resorbable tabs and the one or more samples of graft material comprise apertures; and

attaching the one or more samples of graft material to the tissue expander by causing the resorbable tabs on the tissue expander to engage the apertures on the one or more samples of graft material.

3. A method of making an implantable prosthesis comprising preparing a shell of a silicone breast implant or tissue expander;

providing one or more samples of graft material sized and shaped to conform to a portion of a surface of the breast implant or tissue expander, wherein the graft material is an adipose extracellular tissue matrix that has been treated to produce a three-dimensional porous, or sponge-like material;

attaching the graft material to the shell of the breast implant or tissue expander prior to curing the shell of the silicone breast implant or tissue expander; and

curing the shell of the breast implant or tissue expander and the graft material.

4. The method of claim 3 , wherein the graft material is an acellular tissue matrix.

5. The method of claim 4 , wherein the shell of the breast implant or tissue expander and the adipose acellular tissue matrix are cured such that the curing temperature does not reach a temperature greater than 30° C.

6. The method of claim 4 , wherein the shell of the breast implant or tissue expander and the adipose acellular tissue matrix are cured such that the curing temperature does not exceed 25° C.

7. The method of claim 3 , wherein the shell of the breast implant or tissue expander and the adipose extracellular tissue matrix are cured at a temperature between 80° C. to 110° C.

8. The method of claim 3 , wherein the graft material is removed from the breast implant or the tissue expander after the curing step.

9. A prosthesis comprising a tissue expander and one or more samples of graft material, wherein the tissue expander comprises resorbable barbs and the one or more samples of graft material comprise slits, and wherein the one or more samples of graft material are attached to the tissue expander by engaging the resorbable barbs on the tissue expander to the slits on the one or more samples of graft material.

10. A prosthesis comprising a tissue expander and one or more samples of graft material, wherein the tissue expander comprises resorbable barbs and the one or more samples of graft material comprise mesh, and wherein the one or more samples of graft material are attached to the tissue expander by engaging the resorbable barbs on the tissue expander to the mesh on the one or more samples of graft material.

11. A method of making an implantable prosthesis comprising providing a tissue expander and one or more samples of graft material, wherein the tissue expander comprises resorbable barbs and the one or more samples of graft material comprise slits; and

attaching the one or more samples of graft material to the tissue expander by engaging the resorbable barbs on the tissue expander to the slits on the one or more samples of graft material.

12. A method of making an implantable prosthesis comprising providing a tissue expander and one or more samples of graft material, wherein the tissue expander comprises resorbable barbs and the one or more samples of graft material comprise mesh; and

attaching the one or more samples of graft material to the tissue expander by engaging the resorbable barbs on the tissue expander to the mesh on the one or more samples of graft material.

13. A method of making an implantable prosthesis comprising preparing a shell of a silicone breast implant or tissue expander;

providing one or more samples of graft material sized and shaped to conform to a portion of a surface of the breast implant or tissue expander;

attaching the graft material to the shell of the breast implant or tissue expander prior to curing the shell of the silicone breast implant or tissue expander;

curing the shell of the breast implant or tissue expander and the graft material; and

removing the graft material from the breast implant or tissue expander after the curing step.

14. The method of claim 13 , wherein the graft material is an acellular tissue matrix.

15. The method of claim 14 , wherein the shell of the breast implant or tissue expander and the acellular tissue matrix are cured such that the curing temperature does not reach a temperature greater than 30° C.

16. The method of claim 14 , wherein the shell of the breast implant or tissue expander and the acellular tissue matrix are cured such that the curing temperature does not exceed 25° C.

17. The method of claim 13 , wherein the graft material is an adipose extracellular tissue matrix that has been treated to produce a three-dimensional porous, or sponge-like material.

18. The method of claim 17 , wherein the shell of the breast material or tissue expander and the adipose extracellular tissue matrix are cured at a temperature between 80° C. to 110° C.

19. The method of claim 13 , wherein the graft material is removed from the breast implant or tissue expander after the curing step.
