Including Ligament Anchor Means Patents (Class 623/13.14)
  • Publication number: 20130144384
    Abstract: A surgical method for anterior cruciate ligament reconstruction includes creating a bone tunnel in a head of a femur of a patient. A connective tissue is inserted into the bone tunnel. A shape memory polymer plug is inserted into the bone tunnel. The plug has a first configuration for insertion and a second configuration for affixation that has a radially expanded dimension that presses the connective tissue against a side wall of the bone tunnel to affix the connective tissue in the bone tunnel. The plug changes from the first configuration to the second configuration in response to an activation temperature equal to or greater than a temperature of the femur.

  • Patent number: 8439976
    Abstract: An adjustable button/loop device for securing biologic material in bone, such as for ACL reconstruction. The device has a pair of button/loop constructs, each including a flexible, adjustable loop integrated with a fixation device (for example, a wedge). Biologic material (for example, soft tissue, graft, ligament or tendon) is secured to the two fixation devices, and the construct is inserted into a pair of bone sockets/tunnels, such as into a tunnel in the tibia and a socket in the femur. The biologic material is secured within the bone by passing the buttons though respective bone sockets/tunnels, flipping and seating the buttons outside the bone, and then adjusting the lengths of the flexible adjustable loops passing through the buttons and the respective fixation devices, with the graft extending between the fixation devices thereby appropriately secured in the bone.

  • Patent number: 8435294
    Abstract: Devices, systems and methods for fixation of tendon to bone are described. An exemplary surgical implant is a modified bone anchor that is able to grasp the tendon and hold it firmly in a bone tunnel. Once deployed, the anchor delivers lateral compression to the tendon, providing direct tendon to bone compression to facilitate healing. The anchor has different versions which allow it to be attached to the tendon prior to insertion into the bone tunnel, or be inserted between tendon arms when the surgical procedure dictates. The resulting tendon to bone compression allows for the firm fixation in a manner markedly simpler than traditional techniques. A modification of this anchor can also allow the anchor to grasp and hold suture. This variation facilitates the technique for knotless rotator cuff repair.

    Abstract: Systems for single tunnel, double bundle anterior cruciate ligament reconstruction include implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. The instruments are also used to exercise and insert the ligament graft constructs. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on a single femoral tunnel, single or double tibial tunnels, and one or more ligament grafts.

  • Patent number: 8414647
    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.

  • Publication number: 20120245686
    Abstract: The ability to advance soft tissue into bone without externalizing it is considered an improvement for those knowledgable in the art of soft tissue fixation into bone. The above device/implant fixates soft tissue directly, then allows for fixation through a bony hole or aperture into a tunnel or void. It does not require interference fixation (eg. with a screw, or similar implant that fills a bony tunnel with soft tissue interposed). However, it does not preclude subsequent fixation that relies on interference fixation. The claims of this application disclosure for direct soft tissue fixation and subsequent bony fixation using the features of the described device/implant and insertor, as described in detail, are novel in this setting.

  • Publication number: 20120203341
    Abstract: A biologic diarthrodial joint includes an artificial subchondral bone shaped in the form of a joint replacement member and formed of an artificial fiber material. The artificial fiber material includes synthetic fibers formed in a fibrous network with the synthetic fibers arranged in multiple orientations. The artificial subchondral bone includes a polymer receiving component. An artificial cartilage polymer is cooperable with the artificial subchondral bone and engages the polymer receiving component. The artificial cartilage polymer has physical properties similar to that of native articular cartilage.

  • Publication number: 20120203339
    Abstract: Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A tissue anchoring device is described that comprises an anchor body and a spreader such that tissue may be captured or compressed between outside surfaces on the anchor and inside surfaces of a bone tunnel to secure the tissue within the tunnel. An anchoring device is described that comprises an anchor body having compressible tabs with teeth, and a spreader that forces the compressible tabs into an expanded state when inserted into anchor body, facilitating engagement between bone and the teeth of the compressible tabs. Also described is an inserter tool that can be used to insert the anchor into bone and move the spreader within the anchor to expand the anchor and capture the tissue between the anchor and the bone. Methods are described that enable use of the bone anchoring device to secure a tissue graft into the tibial and femoral bones during anterior cruciate ligament (“ACL”) reconstruction.
