  • Patent number: 10888312
    Abstract: A suture securing assembly comprises a two-bodied anchor and an associated delivery system which enhances fixation of a micro anchor in a bone hole or tunnel, as well as improving suture lock within bone. Initially, the two bodies are separated by a length of an inner shaft of the delivery system. The proximal body is fixed on the inner shaft of the delivery system and cannot move relative to the handle until after insertion into the bone, when the delivery system is disengaged from the anchor. The distal body further includes expansion wings and/or other features for increasing suture lock within the bone hole.

  • Patent number: 10869724
    Abstract: The invention relates to a method of determining the sagittal rotation of a patient's pelvis based on a standard anterior posterior X-ray-image with known image parameters and a calibration of the image, for example by using at least one King-Mark calibration object. The angle of the pelvic rotation is determined between a pelvic plane which is orthogonal to the midsagittal plane of the pelvis, and the image plane of the X-ray-image. Assuming the patient's position shown on the X-ray-image represents a standard neutral position, the X-ray-image plane can be used as a functional reference plane for further calculations, for example during hip-replacement surgery. The present invention further relates to a corresponding computer program and system.

  • Publication number: 20200390453
    Abstract: Embodiments of the present disclosure are directed to instrumentation that facilitate coracoid-glenoid fixation in Latarjet procedures. For example, a single instrument, a coracoid resection tool, may be provided/utilized to prepare a coracoid bone graft for size, flatness, and hole drilling. A glenoid drill guide may further be provided/utilized that uses sized offsets for placement of the coracoid graft flush with the glenoid. Further embodiments of the disclosure are directed to corresponding methods that employ this instrumentation. For example, a surgeon may employs the coracoid resection tool as a guide to plane the inferior coracoid surface that will serve as the coracoid graft surface. The coracoid resection tool may further guide the placement of coracoid holes along the length of the coracoid and orient the holes approximately perpendicular to the planed coracoid graft surface. For example a proximal coracoid hole may be positioned towards the proximal end (i.e.

  • Patent number: 10849757
    Abstract: A soft anchor surgical fixation device includes two soft anchoring implants. The implants have a first elongate state where the implants may slide easily through a bone hole or tunnel, and a second axially compressed state where the implants are prevented from sliding through the bone hole or tunnel. The device also includes a suture pathway extending at least partially along and through the sidewalls of the implants. Tension on the suture transitions the implants from the first elongate state to the second compressed state.

  • Publication number: 20200367879
    Abstract: Bone anchors having improved fixation are discussed. The bone anchors include an anchor body and radially protruding ribs that extend approximately parallel to a longitudinal axis of the bone anchor. A leading distal edge of each rib may be configured in a tapered “knife-edge” configuration. Such ribs may mitigate the plow-out effect, preserving contact between the ribs and the surrounding bone along the length of the anchor. Furthermore, such ribs provide increased surface area, improving fixation strength.

  • Publication number: 20200360010
    Abstract: Tissue repair assemblies for repairing soft tissue consist of two soft anchors connected by a suture. Each soft anchor is a woven braid with a suture stitched through opposite sides of the anchor. The suture includes a pre-tied sliding knot located between the anchors. When the anchors are deployed in the body and the knot is reduced toward the tissue, the suture slides through the anchors, causing them to expand radially or fold to form a ball shape or cluster, thus increasing the contact area against the tissue and improving the overall construct strength.

  • Publication number: 20200360007
    Abstract: Anchor delivery systems include anchors having a generally cylindrical body with a rail on top for positioning within a delivery device slot. The rail incorporates a side-bulge as a retaining feature which axially extends along a majority of the length of the rail. The bulge interferes with a corresponding hourglass cutout in the delivery device slot to prevent the anchor from stripping out of the delivery device when the delivery device is retracted through tissue. The anchors are symmetrical along a length and width to facilitate loading within the delivery device. The distal portion of the delivery device includes a series of distally-extending barbs that intentionally change the penetration force required to push the device tip through tissue.
