A device for creating a fistula between blood vessels operates in conjunction with a guidewire to locate and position itself so that it straddles both vessels and is able to draw them together. A fixing agent is released either from within the device or from an external needle, or both, into the procedural site. The fixing agent functions to hold the relative position of the two vessels, to seal the surrounding tissue so that any leaks that do occur don't spread into the tissue to create a hematoma, and to limit expansion of the fistula. After the vessels are in close proximity to each other and the fixing agent is applied, the device of the invention employs a cutting mechanism which opens a portal between the two vessels.

Externally supported anastomosis

A catheter system for creating an arteriovenous (AV) fistula includes a proximal base having a distal end surface. A distal tip is connected to the proximal base and is movable relative to the proximal base. The distal tip has a proximal end surface. The distal end surface and the proximal end surface are adapted to contact opposing sides of a tissue portion to create the fistula. A peripheral edge defines the distal end surface of the proximal base. A stop is formed in the peripheral edge and is configured to limit movement of the distal tip in a proximal direction.

Systems and methods for percutaneous access and formation of arteriovenous fistulas

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.

A catheter system 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, wherein the distal tip has a proximal diagonal end surface. The distal diagonal end surface and the proximal diagonal end surface contact opposing sides of a tissue portion to create the fistula. A peripheral edge defines the proximal distal end surface. A proximal point is disposed on the peripheral edge. The proximal point comprises a shortened angle and a fully radiused edge relative to a remaining portion of the peripheral edge and a relief recess is disposed on a distal end of the proximal base, both for the purpose of minimizing tissue snagging.

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.

Surgical instrument for manipulating and passing suture

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.

Tissue repair assembly

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.

Knotless dynamic suture tensioning device and methods

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.
