  • Publication number: 20140081399
    Abstract: An adjustable, knotless button/loop/needle construct for fixation of cranial cruciate ligament deficient stifle. The adjustable, knotless construct includes two fixation devices (for example, two buttons) and at least one flexible, adjustable loop attached to at least one of the fixation devices (e.g., the buttons). Preferably, a needle is attached to each of the fixation devices (e.g., the buttons). The adjustable, knotless construct has an adjustable loop length and allows adjustment in one direction while preventing or locking the construct from loosening in the opposite direction, due to applied tensile forces. The construct and technique of the present invention provides an improved knotless system for cruciate ligament repair.

  • Publication number: 20140074239
    Abstract: An adjustable suture-button construct for ligament reconstruction. The construct is a knotless, adjustable, flexible suture loop, a first fixation device (a free or removable slotted button) and optionally a second fixation device (a fixed, non-removable button). Suture ends of the knotless suture loop provide a variable-length graft support that can be adjusted prior to, during, or after deployment of the constructs. The removable, detachable fixation device is provided with attachment feature(s) to permit assembly onto the adjustable loop. The removable, detachable fixation device is attached to the tibia end of the loop construct after the loop construct is passed through the tibial tunnel (i.e., once the loop exits the anterior tibia cortex). If a fixed, non-removable button is employed, the fixed, non-removable button is securely attached (by stitching, for example) to the graft.

  • Publication number: 20140067061
    Abstract: Devices, systems and/or methods for repairing soft tissue, such as, a lacerated tendon. A repair device includes a frame having a tubular structure with a longitudinal length and struts at least partially defining the tubular structure. The frame includes a first portion and a second portion with an intermediate portion therebetween, each extending along the longitudinal length. The intermediate portion is configured to substantially maintain a fixed position and is configured to be positioned over first and second ends of the lacerated tendon to substantially maintain the first end abutted against the second end. The first portion and the second portion of the frame are configured to be positioned over separate portions of the tendon and configured to move and elongate along a length of the respective first portion and second portion of the frame as the portions of the tendon elongate.

  • Patent number: 8663325
    Abstract: The present disclosure relates to a soft tissue graft anchor. The anchor includes a plurality of prongs, each prong including a distal end and a proximal end, wherein the prongs are coupled at their distal ends to form an inner cavity having an opening, at least one of the prongs including a fin, the fin extending perpendicular to a longitudinal axis of the prong and including a pointed end. A tissue graft anchor assembly, a method for tissue repair, and instrumentation for use therewith are also disclosed.

  • Patent number: 8663324
    Abstract: An all-inside double-socket ACL reconstruction technique, according to which a femoral socket and a closed tibial socket are provided to accommodate retrograde fixation of at least one graft (for example, a semitendonosus allograft) within the sockets. The closed tibial socket is formed by using a retrograde drill device provided with a retrograde drill cutter detachable from a retrograde drill guide pin. The femoral socket may be formed by the retrograde drill method or by a conventional method, and may be carried out before or after the formation of the tibial socket. The graft is secured in the knee by employing a transversal implant, or by employing an interference screw, and/or a continuous loop/button construct.

  • Patent number: 8652208
    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.
