  • Patent number: 11642216
    Abstract: 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. The grafts include positional notches for more accurate positioning in a subject. The grafts also include at least one cuff element which is folded to form a reinforced folded edge for suturing the graft more securely to adjacent tissues than previously known grafts. The grafts also include a plurality of arcuate slots which form a plurality of circular patterns arranged concentrically about a focal point, thereby enabling the grafts 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. Acellular dermal matrices are particularly suitable for making the soft tissue repair grafts.

  • Publication number: 20220304794
    Abstract: Methods, systems, and compositions for treatment are provided. The methods can be used to stretch and completely or nearly completely wrap a composition around an implant or tissue expander. The systems can be used to protect an implant or tissue expander by completely or nearly completely wrapping a composition around the implant or tissue expander. The compositions can be used to completely or nearly completely wrap around an implant or tissue expander to provide support and protection to the implant or tissue expander.
