BREAST TREATMENT DEVICE
The present disclosure provides devices for treating breasts. The devices ( 100 ) include a sheet of 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. The sheet includes curved upper and lower borders or edges.
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 first section and a second section, and the first and second sections have different shapes and are attached to one another, and wherein the first section includes curved first and second edges, and the second section includes curved first and second edges.
2 . The device of claim 1 , wherein the first edge of the first section has a degree of curvature that is greater than a degree of curvature of the second edge of the first section.
3 . The device of claim 1 , wherein the first edge of the second section has a degree of curvature that is greater than a degree of curvature of the second edge of the second section.
4 . The device of claim 1 , wherein the first section and second section are attached to one another along the second edge of each of the first section and second section.
5 . The device of claim 1 , wherein the sheet of acellular tissue matrix comprises a dermal tissue matrix.
6 . The device of claim 1 , wherein the acellular tissue matrix is a porcine tissue matrix.
7 . The device of claim 1 , wherein the acellular tissue matrix is a human tissue matrix.
8 . The device of claim 1 , wherein the device further comprises a breast implant or tissue expander.
9 . A method of treatment, comprising:
selecting 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; and
implanting the breast treatment device along with a breast implant or a tissue expander within a breast.
10 - 27 . (canceled)
28 . The method of claim 9 , wherein the method comprises implanting the breast implant or tissue expander anterior to pectoralis muscles.
29 . The method of claim 9 , wherein the sheet of acellular tissue matrix is positioned adjacent to the breast implant or tissue expander to cover substantially all of an anterior surface of the breast implant or tissue expander.
30 . The method of claim 9 , further comprising securing a portion of the sheet of acellular tissue matrix to tissue.
31 . The method of claim 30 , wherein the sheet of acellular tissue matrix is secured to a portion of a chest wall.
32 . The method of claim 9 , wherein the sheet of acellular tissue matrix comprises one of a dermal tissue matrix, a porcine tissue matrix, or a human tissue matrix.
33 . A method of treatment, comprising:
selecting a breast treatment device comprising a sheet of acellular tissue matrix according to claim 1 ; and
implanting the breast treatment device along with a breast implant or tissue expander within a breast.
34 . The method of claim 33 , wherein the method comprises implanting the breast implant or tissue expander anterior to pectoralis muscles.
35 . The method of claim 33 , wherein the sheet of acellular tissue matrix is positioned adjacent to the breast implant or tissue expander to cover substantially all of an anterior surface of the breast implant or tissue expander.
36 . The method of claim 33 , further comprising securing a portion of the sheet of acellular tissue matrix to tissue.
37 . The method of claim 33 , wherein the sheet of acellular tissue matrix is secured to a portion of a chest wall.
