  • Patent number: 8469998
    Abstract: A suture anchor comprises a tubular body having an axial bore therethrough and having one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole, such as threads. A lateral port passes through the body from the bore to the exterior surface and is formed of a slot entering the body from its proximal end. A length of suture for attaching soft tissue to bone passes down along the exterior surface over the one or more purchase enhancements, over a distal end of the body, up into the bore through and then back out of the bore and up along the exterior surface over the one or more purchase enhancements.

  • Patent number: 8460309
    Abstract: An inserter for inserting a suture anchor into bone. The inserter has external markings that uniquely identify the orientations and the relative longitudinal positions of at least two suture passages through a suture anchor releasably engaged with the inserter. The markings assist a surgeon in determining a preferred placement and orientation of the anchor at an operative site during a surgical procedure.

  • Patent number: 8449584
    Abstract: A bone anchor is provided that can toggle in two planes for secure anchorage within a bone cavity. The bone anchor includes an oblique suture channel configured such that a suture strand extending through the bone anchor can be tensioned to toggle the bone anchor inside the bone cavity. The suture strand can be located on the same side of the anchor body to maximize the area of the anchor surface which engages bone, resulting in increased engagement into bone and resistance to tensile forces.

  • Patent number: 8317863
    Abstract: A radially expandable sheath is provided having a substantially closed distal end with at least two sidewalls extending proximally therefrom and defining a central lumen. Each sidewall can have a substantially concave outer surface adapted to seat a graft member, and each side wall is at least partially separated by a longitudinally oriented slot that extends from a proximal end along a substantial length of each sidewall. The slot preferably terminates at a position just proximal to the distal end. The device can also include a sheath expander that is adapted to be disposed in the central lumen of the radially expandable sheath and that is configured to flex the sidewalls to radially expand the sheath so as to fix a graft member within a bone tunnel.
