BREAST TREATMENT DEVICE
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.
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 an upper curved border having a first degree of curvature and a lower curved border having a second degree of curvature, wherein the lower curved border is shaped and sized to conform to a desired shape of a lower margin of a breast, and wherein the upper curved border is sized and shaped such that the flexible sheet of acellular tissue matrix can cover substantially all of the anterior surface of a breast implant or tissue expander when implanted in a breast.
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 includes 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.
8 . The device of claim 7 , wherein the group of holes are located on a lower half of the tissue matrix.
9 . 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 comprises a lower curved border and an upper curved border, wherein the upper curved border and lower curved border are joined at apices at lateral ends of the device, and the sheet is symmetrically shaped about an axis midway between the apices and parallel to the top and bottom surfaces when lying on a flat surface, wherein the lower border forms a single outward arc shape, and wherein the upper border has three arc sections including first and second sections each extending from one of the apices, and a third section joining the first and second sections, the third section having a degree of curvature that is different than the degree of curvature of the first and section sections.
10 . The device of claim 9 , wherein the sheet of acellular tissue matrix comprises a dermal tissue matrix.
11 . The device of claim 9 , wherein the acellular tissue matrix is a porcine tissue matrix.
12 . The device of claim 9 , wherein the acellular tissue matrix is a human tissue matrix.
13 . The device of claim 9 , wherein the device further comprises a breast implant or tissue expander.
14 . 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 an upper curved border having a first degree of curvature and a lower curved border having a second degree of curvature, wherein the lower curved border is shaped and sized to conform to a desired shape of a lower margin of a breast.
15 . The device of claim 14 , wherein the sheet of acellular tissue matrix comprises a dermal tissue matrix.
16 . The device of claim 14 , wherein the acellular tissue matrix is a porcine tissue matrix.
17 . The device of claim 14 , wherein the acellular tissue matrix is a human tissue matrix.
18 . The device of claim 14 , wherein the device further comprises a breast implant or tissue expander.
19 . The device of claim 14 , wherein the acellular tissue matrix include one or more holes or openings.
20 . The device of claim 19 , wherein the holes or openings include a group of holes passing through the tissue matrix.
