Abstract

The present disclosure provides devices and methods for treating breasts. The devices can include an acellular tissue matrix having a predefined shape that allows for complete or enhanced coverage of an anterior portion of a breast implant or tissue expander or to support an implant and/or surrounding tissues.

First claim

What is claimed is:

1. 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 and a bottom surface, wherein the sheet has a continuous upper curved border having a first degree of curvature and a continuous lower curved border having a second degree of curvature, wherein the continuous upper curved border and continuous lower curved border are joined at lateral apices separated by a distance between about 15-30 cm and the continuous upper curved border and continuous lower curved border define a height of at least 15 cm to allow complete coverage of an anterior surface of a breast implant, wherein the continuous lower curved border is shaped and sized to conform to a desired shape of a lower margin of a breast;
an upper section extending between the upper curved border and the lateral apices; and
a lower section extending between the lower curved border and the lateral apices;
wherein the upper section has a larger surface area and a larger height than the lower section.

2. The device of claim 1 , wherein the sheet of acellular tissue matrix comprises a dermal tissue matrix.

3. The device of claim 1 , wherein the acellular tissue matrix is a porcine tissue matrix.

4. The device of claim 1 , wherein the acellular tissue matrix is a human tissue matrix.

5. The device of claim 1 , wherein the device further comprises a breast implant or tissue expander.

6. The device of claim 1 , wherein the acellular tissue matrix include one or more holes or openings.

7. The device of claim 6 , wherein the holes or openings include a group of holes passing through the tissue matrix.
