    Abstract: A soft tissue fixation system, most typically applicable to orthopedic joint repairs, such as anterior cruciate ligament (ACL) knee repair procedures, comprises an implant which is placeable in a tunnel disposed in a portion of bone, wherein the tunnel is defined by walls comprised of bone. A first member is deployable outwardly to engage the tunnel walls for anchoring the implant in place in the tunnel, and a second member is deployable outwardly to engage tissue material to be fixed within the tunnel. The second member also functions to move the tissue material outwardly into contact with the tunnel walls to promote tendon-bone fixation. Extra graft length is eliminated by compression of the tendon against the bone at the aperture of the femoral tunnel, which more closely replicates the native ACL and increases graft stiffness. The inventive device provides high fixation of tendon to bone and active tendon-bone compression.

  • Patent number: 8133257
    Abstract: A bioabsorbable suture anchor for anchoring soft tissue to a bone is provided. The suture anchor is configured to toggle and anchor itself inside a bone cavity of a small joint. The anchor comprises an elongate body defined by a longitudinal axis, a first, leading end and a second, trailing end. The elongate body also has two opposed surfaces between the first and second ends, and a plurality of sidewalls extending between the two opposed surfaces. Extending from one of the sidewalls is a flared portion that is formed on the second end of the elongate body. The flared portion is adapted to engage and anchor into bone tissue upon toggling. A suture channel extends between the two opposed surfaces. The suture channel is formed in the elongate body for passage of a suture strand therethrough, such that pulling on an attached suture strand effects toggling of the anchor inside a bone cavity.

  • Patent number: 8128669
    Abstract: A retainer member formed of bone secures tissue relative to a bone. The retainer member forms an opening in a compact outer layer of the bone. The retainer member is enclosed in a tubular member or sleeve to prevent breaking of the retainer member during formation of the opening in the bone. The extent of movement of the retainer member into the hone in the patient's body is determined as the retainer member is moved into the bone. A suture may be connected with the retainer member and used to connect tissue with the bone. The retainer member may be positioned across a fracture in a bone to hold portions of the hone relative to each other. The retainer member may be used at a joint between end portions of bones to immobilize the joint and be released by breaking the retainer member.

  • Patent number: 8109966
    Abstract: An innovative bone anchor and methods for securing connective tissue, such as tendons, to bone are disclosed which permit a suture attachment which lies entirely beneath the cortical bone surface, and wherein the suturing material between the connective tissue and the bone anchor is oriented in a direction generally transverse to the longitudinal axis of the bone anchor, so that axial pull-out forces exerted on the bone anchor are minimized. The suture attachment to the bone anchor involves the looping of a substantial length of suturing material around a shaft of the anchor, thereby avoiding an eyelet connection which requires a knot and which concentrates stress on a very small portion of the suturing material. Thus, failure rates are greatly decreased over conventional techniques, and the inventive procedures are significantly easier to perform than conventional techniques.

  • Publication number: 20120022535
    Abstract: The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions (1) and arranged therebetween a stabilization portion (2). The anchorage portions (1) include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion (2) preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions (1) have a greater thickness (T1) and a greater depth (D) than the stabilization portion (2). Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face (4) of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.
