  • Muscle-based grafts/implants
    Publication number: 20060251629
    Abstract: The present invention is directed to a composition comprising a matrix suitable for implantation in humans, comprising defatted, shredded, allogeneic human muscle tissue that has been combined with an aqueous carrier and dried in a predetermined shape. Also disclosed is a tissue graft or implant comprising a matrix suitable for implantation in humans, comprising defatted, shredded, allogeneic human muscle tissue that has been combined with an aqueous carrier and dried in a predetermined shape. The composition and/or tissue graft or implant of the invention is usable in combination with seeded cells, a tissue growth factor, and/or a chemotactic agent to attract a desired cell.

  • Process and apparatus for treating implants comprising soft tissue
    Publication number: 20060228252
    Abstract: The present invention is directed to the field of implants that include soft tissue. More particularly, the present invention is directed to processes for treating implants that include soft tissues such as tendons, ligaments and meniscus, and to implants produced by such processes. The present invention is also directed to processes and apparatus for improved processing of implants that include soft tissue, by applying kinematic restraint, preferably tension, to the implant or specific portions of the implants during the treatment, and to implants produced by such processes and apparatus. The present techniques yield soft tissue implants having superior structural, mechanical, and/or biochemical integrity.

  • Matrix composition for human grafts/implants
    Patent number: 7001430
    Abstract: The present invention is directed to an intermediate composition for producing a muscle tissue matrix suitable for implantation in humans, comprising shredded, allogeneic human muscle tissue that has been combined with an aqueous carrier, preferably a biocompatible acid solution, to form a muscle tissue slurry having a viscosity within the range of 1 centistoke to 20,000 centistokes measured at 25° C. In another aspect, the present invention is directed to a tissue implant comprising a human muscle tissue matrix.
