  • Patent number: 9526606
    Abstract: A method of revising a graft in a bone tunnel including unpinning a graft ligament support block from within a bone tunnel in a host bone, withdrawing the graft ligament support block from the bone tunnel to create a vacated bone tunnel, advancing a graft ligament support block into the vacated bone tunnel, and pinning the graft ligament support block within the bone tunnel. In one embodiment, the graft ligament support block includes a body having a graft hole and a transverse fixation pin hole extending through the body. The graft hole and the transverse fixation pin hole extend substantially perpendicular to the longitudinal axis of the body. An installation tool can be provided for inserting the graft ligament support block into the bone tunnel.

  • Patent number: 7862612
    Abstract: A method and apparatus for reconstructing a ligament using a graft ligament support block which comprises a body, and a graft hole and a transverse fixation pin hole extending through the body, with both the graft hole and the fixation pin hole preferably extending substantially perpendicular to the longitudinal axis of the body. A graft ligament is looped through the graft hole, and the support block is advanced into the bone tunnel, with the two free ends of the looped graft ligament extending back out the bone tunnel. Next, a transverse tunnel is formed in the host bone, with the transverse tunnel being aligned with the fixation pin hole. Then the support block is secured in place by pinning the support block within the tunnel, i.e., by advancing a fixation pin along the transverse tunnel in the host bone and into the fixation pin hole in the support block.

  • Patent number: 7819888
    Abstract: A system for transplanting a bone plug from a donor site to a recipient site extracts the bone plug from the donor site, and then places a bone plug delivery device having a tip which is at least translucent and, preferably, clear over a tube containing the bone plug. The tip is then placed substantially over a pre-formed hole in the recipient site, whereafter the bone plug is forced from the tube, through the transparent tip, and into the pre-formed hole.

  • Patent number: 7520898
    Abstract: A graft ligament is looped through a graft hole in a graft ligament support block, and the graft ligament support block is mounted to an installation tool. Then the installation tool is used to advance the graft ligament support block into a bone tunnel, with the two free ends of the looped graft ligament extending back out the bone tunnel. Next, a transverse tunnel is formed in the host bone, with the transverse tunnel being aligned with a transverse fixation pin hole in the graft ligament support block. Then the graft ligament support block is secured in place by pinning the graft ligament support block within the tunnel, i.e., by advancing a transverse fixation pin along the transverse tunnel and into the transverse fixation pin hole in the graft ligament support block. Then the installation tool is detached from the graft ligament support block and withdrawn from the surgical site.

  • Patent number: 7074203
    Abstract: A rivet-like bone anchor has a floating washer at its head that can adapt to an angled bone surface and, thereby, better secure a tissue thereto. The anchor includes a rivet, an expandable sleeve, and a washer. The rivet includes a head and an elongate body having proximal and distal ends, the head being mounted on the proximal end of the elongate body. The expandable sleeve has an inner bore adapted to receive the rivet body. The washer “floats” at a proximal end of the sleeve. As the rivet is inserted into sleeve, the sleeve expands into an interference fit with the bone. The head of the rivet, moreover, forces the floating washer into contact with the tissue at an angle that conforms to that of the underlying bone surface. A deployment tool permits the anchor to be deployed without application of unnecessary counterforce. The tool includes an outer tube, the distal end of which can hold the anchor housing, e.g., via a screw fit.
