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.

Claims

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.
