         32 . The device of  claim 29 , wherein the second end of the device comprises a rounded edge. 
     
     
         33 . The device of  claim 28 , wherein the tissue matrix comprises a tissue matrix derived from a human tissue. 
     
     
         34 . The device of  claim 28 , wherein the tissue matrix comprises a tissue matrix derived from porcine tissue. 
     
     
         35 . The device of  claim 28 , wherein the tissue matrix comprises a dermal tissue matrix. 
     
     
         36 . The device of  claim 35 , wherein the dermal tissue matrix further comprises an epithelial basement membrane on the top surface of the tissue matrix. 
     
     
         37 . A method of treating a breast, comprising:
 identifying an anatomic site within a breast;   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, a bottom surface, and a peripheral border, and wherein the peripheral border comprises a first edge having a concave shape, and a convex-shaped second edge; and   implanting the treatment device in or proximate the breast; and   securing at least a portion of the treatment device along the second convex-shaped edge to tissue in or near the breast.   
     
     
         38 . The method of  claim 37 , further comprising implanting a breast implant or tissue expander within the breast. 
     
     
         39 . The method of  claim 38 , wherein the breast implant or tissue expander comprises a silicone or saline filled implant or tissue expander. 
     
     
         40 . The method of  claim 37 , wherein the treatment device is implant with the convex-shaped second edge facing inferiorly. 
     
     
         41 . The method of  claim 37 , wherein the tissue matrix comprises a tissue matrix derived from a human tissue. 
     
     
         42 . The method of  claim 37 , wherein the tissue matrix comprises a tissue matrix derived from porcine tissue. 
     
     
         43 . The method of  claim 37 , wherein the tissue matrix comprises a dermal tissue matrix. 
     
     
         44 . The method of  claim 43 , wherein the dermal tissue matrix further comprises an epithelial basement membrane on the top surface of the tissue matrix. 
     
     
         45 . The method of  claim 44 , wherein the treatment device is implanted with the top surface facing towards a chest wall of a patient in which the treatment device is implanted. 
     
     
         46 . A breast treatment system, comprising:
 a breast implant or tissue expander; and   a sheet of acellular tissue matrix, wherein the sheet of acellular tissue matrix comprises a flexible sheet with a top surface, a bottom surface, and a peripheral border, and wherein the peripheral border comprises a first edge having a concave shape, and a convex-shaped second edge.   
     
     
         47 . The breast treatment system of  claim 46 , wherein the first edge and second edge meet at a first end of the device and at a second end of the device. 
     
     
         48 . The breast treatment system of  claim 47 , wherein the first end of the device comprises a first pointed tip. 
     
     
         49 . The breast treatment system  claim 48 , wherein the second end of the device comprises a second pointed tip. 
     
     
         50 . The breast treatment system of  claim 47 , wherein the second end of the device comprises a rounded edge. 
     
     
         51 . The breast treatment system of  claim 46 , wherein the tissue matrix comprises a tissue matrix derived from a human tissue. 
     
     
         52 . The breast treatment system of  claim 46 , wherein the tissue matrix comprises a tissue matrix derived from porcine tissue. 
     
     
         53 . The breast treatment system of  claim 46 , wherein the tissue matrix comprises a dermal tissue matrix. 
     
     
         54 . The breast treatment system of  claim 53 , wherein the dermal tissue matrix further comprises an epithelial basement membrane on the top surface of the tissue matrix.
