  • IMPLANT FOR HERNIA REPAIR
    Publication number: 20150038921
    Abstract: A hernia repair implant includes a first layer for facing a body structure having a hernia defect to cover the defect while promoting tissue growth into the first layer from the body structure. The implant also includes a second layer opposed to the first layer and made of anti-adhesion material to prevent growth of tissue into the second layer from body structures contacting the second layer. Furthermore, the implant includes at least one engagement strap connected to the first layer and extending therefrom to terminate at a free end. The engagement strap defines opposed thin edges and opposed flat surfaces extending between the edges. At least one barb extends from at least one edge and/or at least one flat surface of the strap and is configured to impede motion of the strap in only a single direction.

  • HERNIA REPAIR DEVICE WITH CORE AND ADVANCED PRE-PERITONEAL DISK DEPLOYMENT
    Publication number: 20140350580
    Abstract: An implant to repair a hole in a muscle wall includes a flat mesh with a central resilient core which deforms to place the core in a hole in a muscle wall and then resiliently expands when released to urge against the perimeter of the hole, dynamically “riding” in the hole as the hole perimeter expands and contracts. Straps on the mesh are tunneled through tissue in the muscle wall containing the hole to hold the mesh with core in place.
