Abstract: Various exemplary methods, systems, and devices for blood flow are provided. In general, an implant can be configured to be implanted in bone and to delay clotting of blood flowing from the bone. The implant can include an anti-coagulation agent to delay the clotting of the blood. The anti-coagulation agent can be a coating on the implant, can be natural to a material forming the implant, or can be impregnated into a material forming the implant. In an exemplary embodiment, the implant is implanted in a bone in a surgical procedure for securing a soft tissue to bone, such as a rotator cuff repair procedure or an anterior cruciate ligament (ACL) repair procedure.

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.

Abstract: In general, devices, systems, and methods for relocating tissue during surgeries are provided. In one embodiment, a surgical apparatus is provided that includes a needle, a hook movably disposed in the needle, an actuator, and a slidable member. The needle can be percutaneously advanced through skin of a patient. The actuator can move the hook between two orientations, one being disposed entirely within the needle and another extending from the needle. The slidable member can slide along the needle and abut an exterior surface of the skin of the patient through which the needle is advanced. In use, the hook can engage tissue within the body of the patient when the hook extends from the needle. The surgical apparatus can then move the engaged tissue within the body of the patient, and the engaged tissue can be locked in position relative to the skin.

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.

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.

Abstract: Various exemplary methods for attaching soft tissue to bone are provided. In general, a soft tissue can be attached to a bone of a patient using a collapsible suture and a suture anchor. In at least some embodiments, attaching a soft tissue to bone includes use of a suture anchor and a collapsible suture in the form of a collapsible loop. In at least some embodiments, attaching a soft tissue to bone includes use of a suture anchor and a collapsible suture that is cinched with a cinchable knot.

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.

Abstract: Methods and devices are provided for anchoring graft to bone. In one exemplary embodiment, a bone cavity is created in bone, a graft is partially advanced into the bone cavity, and a hardenable filler material is inserted into the cavity. The hardenable filler material can change from a viscous first state to a harder second state, compressing the graft against the walls of the bone cavity and thereby anchoring the graft within the cavity. The hardenable filler material can be inserted in an open sac, a closed sac, other carriers or housings, or directly into the bone cavity.

Abstract: Methods and devices are provided for preparing and implanting tissue scaffolds. Various embodiments of scribing tools are provided that are configured to mark one or more predetermined shapes around a defect site in tissue. The shape or shapes marked in tissue can be used to cut a tissue scaffold having a shape that matches the shape or shapes marked in tissue. In one embodiment, the scribing tool used to mark a shape in tissue can also be used to cut the tissue scaffold.

Abstract: Various exemplary methods and devices are provided for improved surgical sutures, suture systems, and methods for suturing. In general, the sutures, suture systems, and methods can allow a suture to form a secure, closed loop without tying a knot. The suture can include a barbed portion configured to be threaded through a hollow portion. The barbed portion can have a plurality of barbs thereon, which can grasp onto an inner wall of the hollow portion when disposed therein to help secure the loop at a desired size. The barbs can all be oriented in one direction that corresponds to a direction of movement of the suture when the loop is being tightened. Thus, the barbs can be configured to allow for a size of the loop to be easily reduced to any desired size to approximate tissue, but can be configured to resist subsequent expansion of the loop to ensure that the tissue remains in place.
