摘要：
Soft tissue repair grafts are provided for supporting, covering, and/or retaining an implant positioned in the body of a subject. The grafts are particularly suitable for use for pre-pectoral breast reconstruction with a breast implant or tissue expander. According to the present invention, the graft (10) is planar prior to placement in the patient and comprises an arcuate peripheral edge (12) defining a generally circular or slightly oval shape with a geometric center, a focal point (F) located at or near the geometric center, and a plurality of slots (42a - 42g) which form a plurality of circular patterns (44, 46, 48) arranged concentrically about the focal point, thereby enabling the graft to expand without tearing and to conform more closely to the implant and/or adjacent body tissues such as the breast pocket, than previously known grafts. In the preferred embodiment the grafts also include positional notches (14, 16, 18) for more accurate positioning in a subject and at least one cuff element (20, 22, 24) which is folded to form a reinforced folded edge for suturing the graft more securely to adjacent tissues than previously known grafts. Acellular dermal matrices are particularly suitable for making the soft tissue repair grafts.
