1. A system for creating an anastomosis, comprising:
a catheter having a lumen therethrough, a distal tip having a proximal face, and a proximal base having a distal face;
a shaft fixedly attached to the distal tip and connecting the distal tip to the proximal base, the distal tip being axially movable relative to the proximal base to create a variable gap between the distal tip and the proximal base;
a guidewire extending through the catheter lumen and adapted to guide the catheter to a procedural site;
a cutter disposed on said catheter which is adapted to cut tissues to form a side-to-side anastomosis; and
an injector which is adapted to inject fixing agent into the procedural site, the injector comprising one or more ports in the shaft for injecting fixing agent into the procedural site.
