  • Publication number: 20140121701
    Abstract: A suture anchor assembly includes an anchor having a proximal end, a distal end, a longitudinal axis, a first length, and an internal passage within the anchor. The internal passage begins at an opening in the proximal end and has a second length shorter than the first length. A support structure fixed longitudinally relative to the anchor extends across the internal passage and has a third length shorter than the second length. A suture within the internal passage is received about a distal surface of the support structure. A suture extends out of the opening in the proximal end. A driver includes a cannula having a distal opening and a proximal opening, and the suture is received within the cannula. A first end and the second end of the suture extend outside of the proximal opening, the driver having a drive surface near the distal opening that engages the anchor.

  • Publication number: 20140074164
    Abstract: A suture anchor includes a threaded anchor body, at least one aperture at the distal end of the suture anchor, and at least one groove in communication with the aperture. A suture strand can be inserted into the suture anchor and pass through the aperture, the portion of the suture seated in the groove or grooves being protected from abrasion during installation of the suture anchor.

  • Patent number: 8623052
    Abstract: A suture anchor assembly includes an anchor having a proximal end, a length extending along a longitudinal axis, and a cavity that extends at least partially along the length from an opening located at the proximal end. A portion of the cavity is defined by opposite spaced wall surfaces. A rigid support is fixed at the wall surfaces against relative movement of the anchor along the longitudinal axis, and the rigid support extends across the cavity and between the wall surfaces. The suture anchor assembly further includes a tissue securing suture looped over the rigid support including ends that extend out of the opening. The suture anchor assembly includes a driver having a cannula having a proximal opening. The driver is receivable in a portion of the cavity, and the ends of the at least one tissue securing suture extend out of the proximal opening of the cannula.

  • Patent number: 8343186
    Abstract: A suture anchor has a pin that is disposed transversely within the suture anchor, over which one or more strands of suture is looped. The anchor body is threaded and has a tapered distal portion. The proximal end portion of the suture anchor body has a hexagonally shaped opening to accept a hexagonal drive head. The peripheral surface defining hexagonally shaped opening is rounded and smooth to prevent abrading sutures placed in contact therewith.

  • Publication number: 20110208198
    Abstract: Techniques and instrumentation for elbow reconstruction, specifically, for repairs of the ulnar collateral ligament (UCL). The instrumentation provides for precise formation of sockets and tunnels along with easy suture/graft passage while accommodating all forms of elbow UCL reconstruction techniques. A V-drill guide is provided with a handle and two drill sleeves having intersecting trajectories for creating an intersecting V-shaped bone tunnel in the ulna. An adjustable humeral guide has an adjustable arm with an arc shape, and a peg and a block extending from each end of the adjustable arm. The peg is shaped to fit within an already-formed humeral socket. The block allows a drill to pass through and form other tunnels which intersect with the originally-formed tunnel at various positions.

  • Publication number: 20100262186
    Abstract: A pound-in suture anchor that self-twists upon insertion into a drilled pilot hole. The suture anchor is provided with threads that allow the anchor to be inserted within a pilot hole without tapping the pilot hole and without turning (or twisting) the driver handle. The suture anchor of the present invention is designed to twist by itself as it is advanced into the pre-drilled pilot hole by malleting the driver handle. The suture anchor has an eyelet for receiving one or more suture strands for securing soft tissue to bone.

  • Patent number: 7226469
    Abstract: An insert-molded suture anchor has a biodegradable polymer body molded around a loop of suture. A tapered end disposed on the proximal end of the body is received into a recess in the distal end of a hand driver. Anchoring ribs are formed along the remaining length of the anchor. The suture is held securely within the anchor body during the insert molding process. The anchor is produced by placing the braided suture within an injection mold, and injecting biodegradable polymer into the mold. Using a preferred plication driver, the suture anchor can be utilized for capsular plication procedures.
