  • Patent number: 8398678
    Abstract: A technique and associated instrumentation for correcting large intermetatarsal angles that result from hallux valgus. The system includes a button and a suture loop attached to the button. A suture strand is threaded through holes in the button to attach the button to the suture. The suture ends are then brought together (by being swaged, spliced or cinched together, for example) to form the suture loop comprising a continuous, uninterrupted suture loop with a single strand of swaged-together ends. The swaged-together ends may be attached to a suture passing instrument such as a K-wire (Kirschner wire) that may be further used to drill a hole through the first and second metatarsals. The swaged-together ends of the suture are then passed through the drill holes in the first and second metatarsals; and the ends of the suture are pulled until the button abuts the second metatarsal.

  • Patent number: 8388667
    Abstract: First and second bone segments separated by a fracture line or joint can be fixated or fused by creating an insertion path through the first bone segment, through the fracture line or joint, and into the second bone segment. An anchor body is introduced through the insertion path. The distal end of the anchor body is anchored in the interior region of the second bone segment. An elongated implant structure is passed over the anchor body to span the fracture line or joint between the bone segments. The proximal end of the anchor body is anchored to an exterior region of the first bone segment to place, in concert with the anchored distal end, the anchor body in compression, to thereby compress and fixate the bone segments relative to the fracture line or joint. A bony in-growth or through-growth region on the implant structure accelerates the fixation or fusion of the first and second bone segments held in compression and fixated by the anchor body.

  • Patent number: 8323323
    Abstract: Implants (7) for forming a positive connection with human or animal parts include a material, such as thermoplastics and thixotropic materials, that can be liquefied by means of mechanical energy. The implants (7) are brought into contact with the tissue part, are subjected to the action of ultrasonic energy while being pressed against the tissue part. The liquefiable material liquefies and is pressed into openings or surface asperities of the tissue part so that, once solidified, the implant is positively joined thereto. The implantation involves the use of an implantation device that includes a generator (2), an oscillating element, and a resonator (6). The generator (2) causes the oscillating element to mechanically oscillate, and the element transmits the oscillations to the resonator (6). The resonator (6) is used to press the implant (7) against the tissue part to transmit oscillations to the implant (7).

  • Publication number: 20120191140
    Abstract: An anchor connected with a suture is moved through a passage between opposite sides of a bone. The anchor is then pivoted to change its orientation. A second anchor is connected with the suture. While tension is maintained in the suture, the suture is secured against movement relative to the anchors. This may be done by tying the suture or by using a suture retainer to hold the suture. A suture retainer may be used in place of the second anchor. The passage may extend across a fracture in the bone. The passage may have either a nonlinear or linear configuration. The passage may be formed by first moving a thin elongated member through the bone. The thin elongated member is then used as a guide for a drill. The thin elongated member is withdrawn from the drill and the suture anchor is moved through a passage in the drill.

  • Patent number: 8226714
    Abstract: Various methods and devices are provided for a graft fixation device for fixing a graft member within a bone tunnel. In one embodiment, a graft fixation device is provided having a radially expandable sheath adapted to be disposed within a bone tunnel, and a sheath expander adapted to be received within the radially expandable sheath to expand the sheath and thereby anchor a graft between the sheath and the bone tunnel. In an exemplary embodiment, the graft fixation device is particularly useful to affix a graft within a femoral tunnel.

  • Patent number: 8221455
    Abstract: An apparatus and method for Lisfranc repair using a suture anchor-button construct. The method includes the steps of drilling a hole in a medial cuneiform and through the second metatarsal base, passing the suture anchor of the suture anchor-button construct through the hole from the medial aspect of the medial cuneiform into the hole in the base of the second metatarsal, screwing the suture anchor into the second metatarsal base, advancing the button of the suture anchor-button construct such that the button rests against the medial aspect of the medial cuneiform, and securing the button against the medial aspect of the medial cuneiform.

  • Patent number: 8221477
    Abstract: Implants (7) for forming a positive connection with human or animal parts include a material, such as thermoplastics and thixotropic materials, that can be liquefied by means of mechanical energy. The implants (7) are brought into contact with the tissue part, are subjected to the action of ultrasonic energy while being pressed against the tissue part. The liquefiable material liquefies and is pressed into openings or surface asperities of the tissue part so that, once solidified, the implant is positively joined thereto. The implantation involves the use of an implantation device that includes a generator (2), an oscillating element, and a resonator (6). The generator (2) causes the oscillating element to mechanically oscillate, and the element transmits the oscillations to the resonator (6). The resonator (6) is used to press the implant (7) against the tissue part to transmit oscillations to the implant (7).

  • Patent number: 8216287
    Abstract: A fixation system for a bone conduction device is disclosed. An abutment is coupled to a bone anchor such that vibrations applied to the abutment pass into the bone anchor. The abutment defines a conduction path to the bone anchor such that vibrations applied to the abutment are transferred to the bone anchor. The abutment comprises a plurality of shearing elements disposed adjacent the bone anchor, wherein the shearing elements form part of the conduction path. The fixation system also comprises a vibratory coupler extending from the bone conduction device, comprising a second conduction surface and a magnet, wherein the magnet attracts to the abutment so as to couple the second conduction surface to the abutment, thereby enabling vibrations to pass through the conduction path. The shearing elements are configured to slide laterally in response to tangential forces incident upon the abutment.
