  • Patent number: 11096682
    Abstract: A suture manipulating instrument for passing and retrieving suture through a tissue includes a handle mechanism, an elongate shaft extending from the handle, and a working distal end. The working distal end includes a needle body, a lumen defined by the needle body, a tissue penetrating distal tip, and a lateral slot. A preformed inner member is movably disposed within the lumen of the needle. The handle mechanism is used to extend the wire from the lateral slot of the needle, and to retract the wire into the lateral slot, allowing the working end of the instrument to grasp and manipulate suture by pinning and/or trapping the suture against the needle. In embodiments the inner member is further retracted within the needle lumen, drawing a length of suture into the needle lumen. The suture is subsequently ejected from the needle lumen to form a suture loop.

  • Patent number: 11064992
    Abstract: The present disclosure includes a soft material anchoring system including an elongate, tubular braided soft anchoring implant. The implant has a first elongate state where the implant may easily slide within a bone tunnel, and a second axially compressed state where the implant is wedged within the bone tunnel. The implant also includes at least one suture pathway that extends along and through an implant side wall; this pathway receives at least a portion of a length of suture that is also attached to soft tissue. This length of suture may slide along the suture pathway and transition the implant from the first elongate state to the second compressed state. The system also includes a binding element that at least partially extends within the implant, the binding element having both a first larger binding portion and a second smaller sliding portion.

  • Patent number: 11058417
    Abstract: A device for securing an article to a tissue may include a body, transitionable from a deployment state to a securing state, having a first portion, a second portion, and a medial portion therebetween. The first portion and the second portion may each have an end configured to pierce the tissue. The device in the deployment state may have a linearly extended or a U-shaped structure. In the securing state, the first portion may be embedded in the tissue and the medial portion may contact the article. A system for securing the article to the tissue may releasably engage the device while in the deployment state. A method for securing the article may include contacting the article with a tissue surface and releasing the device from the system so that the device, in the securing state, may anchor the article to the tissue.

  • Publication number: 20200367956
    Abstract: A device and method for creating an arteriovenous (AV) fistula includes a proximal base having a distal diagonal end surface and a distal tip connected to the proximal base and movable relative to the proximal base. The distal tip has a proximal diagonal end surface. A heating assembly, including an energized heating element, is disposed one of the distal diagonal end surface and the proximal diagonal end surface. A passive heating assembly is disposed on the mating diagonal end surface. The distal diagonal end surface and the proximal diagonal end surface are adapted to contact opposing sides of a tissue portion to create a fistula. The angle of the proximal diagonal end surface matches the angle of the distal diagonal end surface, so that the two surfaces match one another during deployment.

  • Patent number: 10765418
    Abstract: Two spaced bodily tissues are approximated with a surgical tensioning device comprising a resilient member and a pressure locking device. The method comprises a step of routing one end of a length of suture through both spaced bodily tissues and inserting the suture end into and through the pressure locking device. The suture is then tensioned by pulling on the suture end passing through the pressure locking device. Responsive to tension changes in the suture, the pressure locking device is actuated by moving at least one surface in the pressure locking device to clamp the suture in position.

  • 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: 9357993
    Abstract: An innovative bone anchor and methods for securing soft tissue, such as tendons, to bone, which permit a suture attachment that lies entirely beneath the cortical bone surface. The suturing material between the soft tissue and the bone anchor may be secured without the need for tying a knot. The suture attachment to the bone anchor involves the looping of a length of suture around a suture return member or path within the bone anchor, tightening the suture and attached soft tissue, and compressing the suture against the bone anchor. The bone anchor may be a tubular body having a lumen with a locking plug that compresses the suture therein. One of the components of the locking structure may include a deformable or flexible section, member, or surface. The locking plug may include a shaft and an enlarged head that interferes with the tubular body to provide a positive stop.

  • Publication number: 20160066901
    Abstract: A bone anchor insertion device comprises a handle, a nosepiece connected to a distal end of the handle, a bone anchor connected to the nosepiece, and an actuator disposed on the handle for deploying the bone anchor, which suture is also fixed to a portion of soft tissue to be attached to a portion of bone. A suture ratchet or tensioning mechanism is disposed in the handle for tensioning suture which is associated with the bone anchor. This mechanism permits precise tensioning, while also permitting one-handed operation, thereby allowing the practitioner to use his or her other hand for other activities, such as camera operation or the like.
