  • Patent number: 9277917
    Abstract: A lattice stitch surgical tension-limiting device, designed to be used in lattice stitch repair of wounds in biologic tissue. The device is tied to the surface of biologic tissue to be repaired by a lattice stitch. The device is designed to limit the tension in the lattice stitch, to allow placement of the lattice stitch without the need of an assistant and “instrument tie”, to help displace tension away from the surface of the body tissues, to enhance the properties of the lattice stitch in tissue shear reduction, and manage rotational forces affecting the repair as the lattice stitch draws the wound together to a closed condition. The device remains on the tissue surface during the wound healing period and is removed with the lattice stitch when wound healing is complete.

  • Patent number: 9034012
    Abstract: A lattice stitch and stitching method for closing wounds are characterized by the use of a tension limiting device. First and second anchor stitches are arranged in a tissue layer spaced from and generally parallel to the wound, with the first and second anchor stitches being on opposite sides of the wound. A closing stitch is looped around the fist and second anchor stitches and tied to draw the wound to a closed condition. The tension limiting device is used during stitching of the anchor stitches. The device is arranged between the anchor stitches and the tissue layer adjacent to the wound to prevent over-tightening of the anchor stitches and lend support to the closure. The tension limiting device can be used in any soft tissue surgical application to displace and disperse suture tension at the surface of the underlying soft tissue, to fasten a dressing to the surface of a wound, and to bolster skin graft repairs of wounds.
