  • Publication number: 20200121445
    Abstract: A knotless anchor for attachment of tissue to bone includes a rigid anchor body and a suture extending there from. The suture is hollow and includes a fixed limb portion secured to the rigid anchor body. A soft suture tunnel extends in a longitudinal direction through the fixed limb portion of the suture. A free suture limb is passed through the tissue, back to the anchor, and through the soft suture tunnel, thereby creating a closable suture loop around the tissue. Tension applied to the free suture limb closes the suture loop, and approximates the tissue to the anchor body. When the anchor is deployed in a bone hole, external features of the anchor body grip the walls of the bone hole and simultaneously compress the suture, thereby preventing tissue pull-out. Anchor assemblies and methods of tissue fixation are also disclosed.

  • Publication number: 20200085423
    Abstract: A multi-suture knotless anchor and related method for securing soft tissue, such as tendons, to bone are described. The suture anchor includes a body, a sleeve, and an outer deformable bone locking structure. The bone locking structure has a first low profile configuration for insertion into the bone, and a second larger profile configuration for engaging the bone when actuated. The bone anchor and methods permit a suture attachment that lies beneath the cortical bone surface and does not require tying of knots in the suture.

  • Patent number: 10463364
    Abstract: In repairing soft tissue with a bone anchoring instrument (such as reattaching a tendon of a torn rotator cuff), the bone anchoring instrument may be used to anchor the soft tissue to a region of bone. The anchors inserted into the underlying bone may have one or more lengths of suture or wire attached thereto which may be tensioned independently of one another to affix the soft tissue to the bone by having a selector mechanism selectively engage and disengage ratcheted tensioning wheels from one another. Suture loading mechanisms may be employed for passing suture lengths into and/or through the anchors prior to deployment into the bone where such mechanisms may employ suture snares which are configured to reconfigure from an expanded shape through which suture lengths may be easily passed to a low-profile shape which secures the suture lengths within the snare.

  • Publication number: 20190321029
    Abstract: A suturing device for grasping soft tissue and placing stitches in soft tissue during endoscopic procedures is described. An elongate housing with a stationary jaw and a movable jaw disposed at the distal end are configured for grasping and releasing soft tissue. A movable needle disposed within the housing is actuated to engage a length of suture and drive the suture into and through the grasped soft tissue. A suture capture member is disposed on the movable jaw and is configured to allow passage of the needle therethrough while securing a portion of the stitched length of suture.

  • Patent number: 9814565
    Abstract: A suture anchor device and method for attaching soft tissue to bone includes an anchor body and a suture locking wedge movably disposed within the anchor body. The suture locking wedge includes lateral portions which engage slots or windows in the anchor body. Tension applied to one limb of a suture causes the suture locking wedge to translate and rotate to a position which compresses the suture, thereby locking the suture in the anchor.

  • Patent number: 9364210
    Abstract: A suture anchor device and method for attaching soft tissue to bone includes an anchor body and a suture locking wedge movably disposed within the anchor body. Tension applied to one side of a suture causes the suture locking wedge to translate and rotate into a position which compresses the suture, thereby locking the suture in the anchor. A resilient or spring biasing member within the anchor device urges the suture locking wedge to compress the suture, facilitating suture locking.

  • Patent number: 9226742
    Abstract: A suture anchor device and method for attaching soft tissue to bone includes an anchor body and a suture locking wedge movably disposed within the anchor body. Tension applied to one side of a suture causes the suture locking wedge to move in a translational and angular dimension to a position which compresses the suture, thereby locking the suture in the anchor. The anchor body includes tracks or slots which guide the suture locking wedge from the unlocked open configuration to the locked configuration.

  • Publication number: 20150142110
    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.
