  • 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.

  • Patent number: 8545572
    Abstract: One embodiment of the invention includes a sinus tarsi implant with an inverted thread profile having a lip or lips at the thread crest. The lips may help hold tissue in-growth and give greater purchase to the implant. The implant may also include voids that traverse threads. The voids may create an open area for soft tissue to grow into. The voids may be relatively small and consequently promote faster tissue in-growth. Thus, the lips and/or voids limit migration. They do this without creating sharp edges or pressure points (or at least limiting such creation) that are typically associated with techniques (e.g., cutting deep negative thread spaces) used to prevent migration. Therefore, the embodiments of the invention limit migration while also limiting patient discomfort. Other embodiments are disclosed.

    Abstract: An orthopedic screw is used in a fixation device for treating fractures. The device has a body with holes to accept the bone screws. The bone screws have a layer of bioresorbable material on the shaft. Engagement between the bone screws and the body is initially through the bioresorbable material, which engagement rigidly fixes the relative angular orientation between the bone screws and the body when the device is applied to a bone. As the bioresrobable material is resorbed the angular relation between the bone screws and the body is no longer rigidly fixed, thereby effecting a transformation from rigid osteosynthesis to flexible osteosynthesis to allow micromotion between the bone fragments which promotes healing.

  • Patent number: 8449583
    Abstract: An improved fastener apparatus includes an outer sleeve which is moved into a patient's body tissue. A distal end portion of the outer sleeve is expanded in the patient's body tissue. An inner sleeve is moved axially through the outer sleeve and a distal end of the inner sleeve is expanded in the patient's body tissue. The fastener apparatus may be provided with an external thread convolution on either or both of the inner and outer sleeves. During expansion of the distal end portion of either the inner or outer sleeve, a proximal end portion of the outer sleeve may be gripped and pulled to offset forces applied to the distal end portion of one of the sleeves. Although inner and outer sleeves may advantageously be utilized, the fastener apparatus may be constructed with only a single sleeve or three or more sleeves if desired. A secondary fastener assembly may be moved through a main fastener assembly.

  • Patent number: 8439919
    Abstract: An implant (4) is provided with attachment and hole-insert parts (2, 3) with surfaces which have different degrees of finishing and/or degrees of roughness and/or porosities (2f, 2g). Arranged on the surfaces there is at least one dozen (A-B) in which the degree of finishing and/or the degree of roughness and/or the porosity is continuously changed. The changes in porosity in said zones can mirror continuous or discontinuous changes in the bone in question, for example the jaw bone or tooth bone. The continuously changed zones can be obtained with the aid of electrolyte (15) and, connected to the latter, an anode and cathode arrangement (13, 14). When establishing the porosity, it is possible to mask different portions of the respective implant and to control the temperature of the implant.

  • 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.
