Abstract: A tissue retractor for retracting tissue opened by an incision, said tissue retractor including a base support unit having a topside and an underside. The topside comprises at least one securing mechanism and the underside is adapted to be conformable and to be removably attachable to a surface proximate to the incision. The tissue retractor also includes at least one tissue hook having a tissue engagement portion and a mounting portion, wherein the tissue engagement portion is capable of engaging at least the periphery of the incision. The tissue retractor also includes at least one retractable member substantially inelastic in its central longitudinal axis and bendable in any axes deviating from said central longitudinal axis. The retractable member is adapted to receive the mounting portion of the tissue hook, wherein said retractable member is adapted to be removably attachable to said securing mechanism on the topside of the base support unit, and wherein said retractable member is retractable away from the incision, such that the tissue engagement portion retracts tissue it is engaged to.

Abstract: A hernia repair implant (26) 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 (50) 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 (52) 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.
