Claim Text:
1. A method for advancing a catheter distally through opposed first and second luminal walls of first and second body lumens, the method comprising: positioning a catheter with a distal tip proximal to the first luminal wall, the catheter including a stent; providing an electrical current to a conductive portion of the distal tip; advancing distally the distal tip of the catheter through the first and second luminal walls to create a passage therethrough, wherein the conductive portion of the distal tip includes a first cutting feature and one or more projections extending proximally from the first cutting feature towards a region of the distal tip having a larger outer diameter than that of the first cutting feature; deploying a distal flange of the stent in the second body lumen; and drawing proximally on the distal flange to pull the first and second luminal walls towards each other.
