  • Patent number: 8852250
    Abstract: The subject invention is a fixation device or anchor intended to secure a graft ligament or other soft tissue repair. The device is designed to be attached to a graft ligament and to secure the graft within a bone tunnel by extending transversely across the opening of the tunnel. In certain procedures the device is intended to pass through a bone tunnel in an orientation generally aligned with the tunnel and then turn transversely. The device has an inherent tendency to rotate upon exiting the tunnel to thereby become automatically transversely aligned with the tunnel and the graft ligament. The rotation is due to a moment automatically created as a resultant of forces applied to the anchor by a pulling-suture via a laterally offset aperture joining the pulling-suture to the anchor.

  • Patent number: 8764798
    Abstract: Methods and apparatus described herein provide for a knotless suture anchor that captures and secures a suture by pinching on an inserted suture with a flexible element disposed within the knotless suture anchors body. The knotless suture anchor has an integrated flexible element that is formed as a plastic part within the knotless suture anchor's body. The free end of the flexible element terminates near a suture eyelet and can be compressed by a driver rod that is inserted into the knotless suture anchor to allow for insertion of a suture. With the flexible element compressed by the driver rod, the suture can be passed through the eyelet(s). When the driver rod is withdrawn, the flexible element expands thereby pinching the suture against the eyelet(s). If the driver rod is reinserted, the flexible element is recompressed and the suture can thereby be released or adjusted.

  • Patent number: 8734462
    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.

  • Patent number: 8679167
    Abstract: A system and method for facilitating the fixation of bone fractures is disclosed. The head component includes a tip, cutting threads and mating threads which are inserted into the far cortex of the bone. A wire extends from the head component and exits from the near cortex. A cap device includes a tension spring, wherein the tension spring is configured to assert friction against the wire when the cap is translated in one direction, but minimal friction against the wire when the cap is translated in the opposite direction. The cap is threaded over the wire such that the cap is restricted from backwards movement. Tension is then applied to the wire while the cap is tightened against or within the bone surface to apply an appropriate amount of pressure between the surfaces of the fracture. The excess wire beyond the cap can then be removed.
