  • Patent number: 12245760
    Abstract: A suture anchor for knotless fixation of tissue. The suture anchor includes an implant configured to hold a suture to be anchored in bone without requiring suture knots. The suture is secured in bone by inserting the implant holding the suture into a hole in the bone, and advancing a fixation device, such as a cannulated interference screw, over a shaft at the proximal end of the implant.

  • Publication number: 20240407778
    Abstract: A suture anchor includes an anchor body having a longitudinal axis, a proximal end, and a distal end. The anchor body includes a central bore located at the proximal end and a passage extending between the central bore and the distal end. The central bore has a first dimension substantially perpendicular to the longitudinal axis, and the passage has a second dimension substantially perpendicular to the longitudinal axis less than the first dimension. The suture anchor includes a flexible strand extending through the passage, and a first knot formed in the flexible strand at the distal end has a third dimension greater than the second dimension to prevent the first knot from passing through the passage. A closed loop is positionable at least partially within the central bore and formed entirely by the flexible strand without forming any additional knots on the flexible strand extending proximally from the first knot.

  • Publication number: 20240081806
    Abstract: Systems and methods for soft tissue to bone repairs employing tensionable knotless anchors, without knot tying. The tensionable knotless anchors may be used by themselves or in combination with additional constructs (which may have a similar or different configuration, i.e., modified according to the specific repair) to achieve novel remplissage and soft tissue repairs.

  • Publication number: 20240074745
    Abstract: Knotless surgical constructs and methods of tissue repairs. A surgical construct can offer both repair and shuttling capabilities to allow for a single pass to load multiple sutures at once. A surgical construct can pass or shuttle multiple repair sutures while making a single pass through or around soft tissue.

  • Publication number: 20230346365
    Abstract: Surgical anchor assemblies and method of tissue repair using the same. The surgical anchor assemblies have a cannulated fixation device, an implant configured to be coupled to the fixation device, and a stop mechanism for preventing relative movement between the fixation device and the implant, such that the fixation device and the implant are configured to rotate together, and a flexible strand winds up to reduce any slack in the flexible strand used for the repair.

  • Publication number: 20230248354
    Abstract: Surgical devices and methods of tissue repair using tensionable knotless fixation devices. A flexible material (for example, suture or suture tape) may be attached to the fixation device. A flexible material may be threaded through an eyelet of a tip provided as part of a swivel anchor assembly to provide added stability to the fixation devices.

  • Patent number: 11690610
    Abstract: Suture constructs and methods for soft tissue to bone repairs. The suture construct is a soft, suture-based anchor which is self-cinching and has a specific, accordian-type configuration (i.e., with the ability to fold from a first, extended position to a second, folded or compressed position). The suture-based anchor may be formed essentially of a flexible material such as a high strength surgical suture, suture chain, or suture.

  • Patent number: 11684356
    Abstract: Surgical constructs and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair constructs include a fixation device, a flexible strand, and a shuttle/pull device attached to the flexible strand and provided within the body of the fixation device. A splice is formed by pulling on the shuttle/pull device to allow desired tensioning of soft tissue to be fixated or repaired relative to the bone.
