  • Publication number: 20230240674
    Abstract: Surgical constructs and methods are provided for securing soft tissue to bone. One exemplary embodiment of a construct is formed from a suture filament and includes two terminal ends of filament and an intermediate portion disposed along at least a portion of a length extending between the terminal ends. The construct can have a first terminal end that is the first terminal end of the filament, and a second terminal end that includes a loop. The loop can be formed by disposing the second terminal end of the filament within a volume of a portion of the intermediate portion of the filament. In some disclosed methods, both terminal ends of the filament can be passed through tissue when performing soft tissue repairs. Various other embodiments of constructs and methods are provided, including constructs having two or more filaments associated with an anchor and methods of using such constructs.

  • Patent number: 11672647
    Abstract: Methods and devices are provided for anchoring a ligament or tendon to bone. In general, various inserter tools are provided for simultaneously delivering an expandable sheath and an expander into bone. With both components of the implant mounted on the same tool, the sheath and a ligament can be advanced into a bone hole and the expander, which trails behind the sheath during delivery of the sheath, can be advanced into the sheath to expand the sheath and anchor the sheath and ligament within the bone hole.

  • Patent number: 11622848
    Abstract: Various bone anchor assemblies and methods are provided for anchoring tissue to bone. In one embodiment, an anchor assembly for anchoring a tendon to bone is provided and includes a substantially cylindrical sheath having bone-engaging surface features formed on an external surface thereof, and having an inner lumen formed therein and extending from an open proximal end to a substantially closed distal. The substantially closed distal end includes at least one tendon anchoring feature extending distally therefrom and configured to facilitate anchoring of a tendon to bone. The anchor assembly further includes an expander having a generally elongate cylindrical configuration and being sized and shaped to be received within the inner lumen of the sheath.

  • Patent number: 11576769
    Abstract: Methods and devices are provided for anchoring a ligament or tendon to bone. In one embodiment, a surgical implant is provided having a sheath and an expander that is received within the sheath. Various delivery tools, including a sheath inserter and a driver, are also provided. In use, the sheath inserter can be used to position a tendon within a prepared bone hole, and it can be used to deliver the sheath with a guidewire coupled thereto into the bone hole. The driver can be provided for delivering the expander into the sheath. A loader can optionally be used to load the driver and expander onto the guidewire coupled to the implanted sheath.

  • Publication number: 20220338856
    Abstract: Methods and systems are provided for securing tissue to bone. A suture anchor can include an elongate body having a proximal end and a distal end and an external surface with a plurality of longitudinally spaced bone-engaging features formed at least partially circumferentially thereon over at least a portion of a length of the suture anchor. The proximal end can have a lumen extending at least partially into the elongate body and the distal end can have a suture engaging feature proximate thereto. A first series of bone-engaging features can have a dimension that increases from a distal to a proximal end of each bone-engaging feature of the first series of bone-engaging features. A second series of bone-engaging features can have a dimension that decreases from a distal to a proximal end of each bone-engaging feature of the second series of bone-engaging features.

  • Publication number: 20210282763
    Abstract: A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose on a first portion of at least a first limb and has a second portion connected to the filament engagement feature of the anchor. Preferably, at least one free filament limb, which in some embodiments is a length of the first filament and in other embodiments is a second filament, is capable of being passed through tissue to be repaired and has at least one end passable through the noose to enable incremental tensioning of the tissue after the anchor is fixated in bone. The noose strangulates the free filament limb when tension is applied to at least one of the free filament limb and the noose.
