摘要： 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.

摘要： 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.

摘要： 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.
