  • Patent number: 11877738
    Abstract: Methods and systems are provided for securing tissue to bone. A surgical system can include a driver device, an elongate shaft receivable within the driver device and having a dilator feature at its distal end, and a capture suture extending through the shaft such that the capture suture's terminal end portions extend to a more proximal position on the driver and the capture suture forms a loop that extends through an opening formed through a side of the shaft. The loop is configured to receive at least one retention suture therethrough and can be tightened by pulling the capture suture's terminal ends, thereby coupling the retention suture with the suture anchor. Once the shaft is inserted into bone and the loop with the retention suture is closed, the suture anchor is driven distally towards the dilator features and into the bone to secure the retaining suture in the bone.

  • 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: 11666431
    Abstract: Surgical devices and methods are provided for anchoring tissue to bone, and more particularly methods and devices are provided for preventing over-insertion of an expander into a sheath of a two-piece anchor. For example, a tendon anchoring system is provided with an anchor assembly and an inserter tool. The anchor assembly includes a sheath with a threaded lumen and a threaded expander screw configured to be threadably disposed within the sheath to cause the sheath to expand outward. The inserter tool includes an elongate outer shaft with a distal end configured to couple to a proximal end of the sheath, and an elongate inner shaft with a distal drive tip configured to engage a proximal end of the expander screw.

  • Patent number: 11554028
    Abstract: Methods and devices are provided for delivering and affixing tissue replacements. In one embodiment, a tissue scaffold can be delivered into a patient through a cannula to a cavity formed at a defect site in tissue, e.g., cartilage. A delivery shaft can be used to deliver the scaffold through the cannula, and a loading device can help load the scaffold onto the delivery shaft. A delivery guide device can position and temporarily hold the scaffold within the cavity. The delivery guide device can guide one or more surgical instruments to the scaffold to affix the scaffold within the cavity, e.g., to bone underlying the scaffold, using at least one securing mechanism.

  • Patent number: 11413132
    Abstract: Systems and methods for preparing a ligament graft for a ligament reconstruction procedure are provided. In general, the described techniques utilize a graft preparation system having a holder and a delivery suture assembly removably coupled thereto. The delivery suture assembly can include a spine coupled with an anchor suture configured to form a self-tightening knot used to position the assembly around a graft and a plurality of suture windings configured to be affixed to the graft when the assembly is deployed. The assembly is delivered to the graft using the holder and the sutures can be affixed to the graft without penetrating therethrough. The spine helps to evenly distribute the load among the windings compressing the graft which are thus are capable of withstanding increased loads. Thus, an improved, simplified, and time- and labor-saving approach to preparing ligament grafts is provided.

  • Patent number: 11337687
    Abstract: Tissue fixation and repair constructs and methods of repair using the same are provided. An exemplary tissue fixation and repair construct can include a first implantable anchor coupled to a suture having a fixed tail and a tensioning tail. The fixed tail can include an overhand knot located distally adjacent to the finger trap, such that the overhand knot substantially abuts the finger trap when adjacent thereto, a fixed stopper knot configured to prevent further movement of the fixed tail through a second implantable anchor when the second implantable anchor is placed onto the suture, and a finger trap. The tensioning tail can be passed through the finger trap and overhand knot, and can be used to adjust the tension of the tissue fixation and repair construct when the first implantable anchor and the second implantable anchor are inserted into bone.

  • Publication number: 20220087669
    Abstract: Various devices, systems, and methods are provided for allowing surgical instruments to access a body cavity through an access device, such as a cannula. In one embodiment, a cap can be removably and replaceably coupled to a proximal end of cannula and can have an opening therethrough that communicates with an inner passageway of the cannula. Various surgical elements can be passed through the cap and cannula and into a patient when the cannula is positioned within the patient. The cap can have a side slot formed therein. The slot can be configured to allow surgical elements, such as sutures, to pass through the cap and into the cannula. At least one surgical seal can be in the cap and can be configured to receive surgical elements therethrough.

  • Patent number: 11229513
    Abstract: Systems and methods for preparing a ligament graft construct for a ligament reconstruction or repair procedure are provided. In general, the described techniques utilize a reinforcement material having at least one suture tail extending therefrom. The reinforcement material is a ribbon or a ribbon-like flattened portion attached to or integrally formed with the at least one suture tail. To prepare a tissue repair construct, the reinforcement material is positioned on a first surface of a graft to extend from an end thereof and the at least one suture tail, coupled to a needle, is repeatedly passed through the reinforcement material and the surface of the graft to a second surface of the graft, and around a side portion of the graft to thereby create multiple suture loops. The tissue repair construct can be formed on each end of the graft.

  • Publication number: 20210401425
    Abstract: Various self-cinching suture anchors, self-cinching suture anchor systems, and methods of use are provided. In one exemplary embodiment, a suture anchor is provided that includes an outer member and an inner member configured to be received within the outer member. The inner and outer members can define a gap that allows a suture to be movably disposed within the outer member, e.g., within the gap, when the inner member is disposed within the outer member. The inner member can be configured to be secured within the outer member by a knot of the suture having a diameter greater than a width of the gap so as to fix the inner member within the outer member, while still allowing uni-directional tensioning of the suture.
