Abstract

Techniques and devices for improved breast surgeries are provided. The devices can include tissue matrix and synthetic meshes for surrounding breast implants or tissue expanders to provide improved implant outcomes for pre-pectoral implantation or other implantation techniques.

First claim

What is claimed is:

1. A method for treatment of a breast, comprising:
selecting a breast implant or tissue expander;
selecting a synthetic mesh;
selecting a layer of acellular tissue matrix;
applying the synthetic mesh to a posterior portion of the breast implant or tissue expander;
applying the acellular tissue matrix to an anterior portion the breast implant or tissue expander;
securing the synthetic mesh to the acellular tissue matrix; and
implanting the breast implant or tissue expander in an implantation site, wherein the synthetic mesh and the acellular tissue matrix are secured to the breast implant or tissue expander by inserting at least one strap attached to the synthetic mesh through at least one hole in the acellular tissue matrix.

2. The method of claim 1 , further comprising:
adjusting a position and a projection of the breast implant or tissue expander in the implantation site.

3. The method of claim 2 , wherein the position and the projection of the breast implant or tissue expander in the implantation site are adjusted by manipulating the at least one strap attached to the synthetic mesh.

4. The method of claim 1 , further comprising securing the breast implant or tissue expander in the implantation site.

5. The method of claim 1 , wherein the breast implant or tissue expander is implanted anterior to a pectoral muscle.

6. The method of claim 1 , wherein the synthetic mesh comprises polyglycolic acid.

7. The method of claim 6 , wherein the synthetic mesh comprises polyglactin 910.

8. The method of claim 1 , wherein the acellular tissue matrix comprises a dermal acellular tissue matrix.

9. The method of claim 1 , wherein after inserting the at least one strap, a position and a projection of the synthetic mesh and the acellular tissue matrix are adjusted in the implantation site by manipulating the at least one strap.

10. The method of claim 1 , wherein the at least one strap is inserted through at least one hole in the synthetic mesh.

11. The method of claim 10 , wherein the at least one hole in the synthetic mesh is adjacent to the at least one hole in the acellular tissue matrix.

12. A device for breast treatment, comprising:
a breast implant or tissue expander;
a synthetic mesh comprising at least one strap; and
a layer of acellular tissue matrix, wherein the synthetic mesh comprises at least one strap and the acellular tissue matrix comprises at least one hole, and the at least one strap and at least one hole are configured to secure the layer of acellular tissue matrix to an anterior portion of the breast implant or tissue expander and the synthetic mesh to a posterior portion of the breast implant or tissue expander.

13. The device of claim 12 , wherein the synthetic mesh comprises polyglycolic acid.

14. The device of claim 13 , wherein the synthetic mesh comprises polyglactin 910.

15. The device of claim 12 , wherein the acellular tissue matrix comprises a dermal acellular tissue matrix.

16. The device of claim 12 , wherein the at least one strap allows adjustment of a position and a projection of the breast implant or tissue expander in an implantation site.

17. The device of claim 16 , wherein the at least one strap is inserted through the hole in the acellular tissue matrix.

18. The device of claim 12 , wherein the synthetic mesh is configured to be secured to tissue in an implantation site.

19. The device of claim 12 , wherein the synthetic mesh comprises at least two straps.
