  • Patent number: 8192490
    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.

    Abstract: Systems for reducing a fracture in a bone, comprising a bone plate and a polyaxial fastener. In some examples the head of the polyaxial fastener has a deformable portion. As a fastener is inserted into an opening of a bone plate, threads located within the opening deform the deformable portion to secure the fastener in place at a desired angle within the opening. The head of the fastener also includes a bottom portion that bears against a portion of the opening to move the bone plate relative to the underlying tissue. A securing member or other structure may be included at the interface of the head and the deformable portion to secure the deformable portion to the head. At least one flute may be included on the deformable portion that provides a lead-in for the threads within the opening to cut into the deformable portion.

  • 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.

  • Patent number: 8075579
    Abstract: Minimal Invasive Spine Surgery (MISS) as a surgical approach is increasingly utilized because of the advantages it offers over conventional spine surgery. The smaller incision results in decreased tissue damage, less blood loss, decreased hospital stay & faster postoperative recovery. The drawbacks of MISS are the long learning curve of working through a smaller incision, longer length of surgery, & potential higher complication rate due to compromised visual field. These limitations can be overcome by more effectively using imaging and navigational devices. The pedicle device simplifies the hardest part of MISS instrumented fusion of conventional pedicle screw insertion by introducing a percutaneous temporary device to locate and create the channel for later conventional pedicle screw implantation using available imaging techniques.

The improvement, for preventing the suture from migrating through the bone at the end of the opening, includes placing a eyelet into an end of the bone opening and passing the suture through the eyelet, as well as through the opening in the bone, in order to affix the soft tissue to the bone with the suture.

  • Patent number: 8062338
    Abstract: An adjustable transverse connector connects orthopedic stabilization rods that may be parallel or skewed in orientation relative to each other The connector may include two sections that are joined together by a fastener. The connector may be adjustable in many ways. The overall length of the connector may be adjustable. The rod openings of the connector may be partially rotatable about a longitudinal axis of the connector. The two sections of the connector may be angulated. The connector may include cam locks that securely attach the connector to the rods. Rotating a cam lock may extend a rod engager into a rod opening. The rod engager may be a portion of the cam lock. The extension of the rod engager into a rod opening may push a rod against a body of the transverse connector to form a frictional engagement between the connector, the rod, and the rod engager.

  • Publication number: 20110263945
    Abstract: A minimally invasive system includes a bone screw and a tissue retractor having distal and proximal end portions and a partial pathway therebetween. The tissue retractor is removably couplable to the bone screw. An instrument has distal and proximal end portions and a hollow cavity and is removably couplable to the tissue retractor. A drive shaft has a diameter less than a diameter of the hollow cavity and is rotatable with respect to the instrument. A counter-torque handle has gripping and an interlock end portions with an instrument interface releasably positioned within the hollow cavity at the proximal end portion thereof and rotatably fixed thereto in an assembled configuration. The interlock end portion also includes an open-ended slot having a width greater than the drive shaft diameter such that the counter-torque handle is movable to and from the assembled configuration while the drive shaft is within the hollow cavity.

  • Patent number: 8006700
    Abstract: A medical fastener (18), preferably bioabsorbable, is used for repairing torn soft tissue, particularly meniscal tissue (16). The fastener (18) can have an enlarged head (22) at the proximate end to engage meniscal tissue (16) adjacent to a tear (14), and a pointed distal tip (21) at the other end to ease insertion of the fastener (18) into the meniscus (16). The shank (20) of the fastener (18) bridges across the tear (14). Opposite ends of the shank (20) are secured in the meniscal tissue (16) by a medical adhesive, preferably bioabsorbable, and preferably at locations remote from the tear (14) so as not to interfere with healing of the tear (14). The fastener (18) can have a blind bore (24) opening through the head (22) of the fastener (18) and extending through the shank (20) to a location close to the tip (21) and generally radial holes (26) communicating between the bore (24) and the exterior of the shank (20).
