A system for forming a fistula between two vessels comprising:
- a first catheter comprising a housing and an electrode,
- wherein the electrode comprises a proximal end, a distal end, and an intermediate portion between the proximal end and the distal end;
- wherein the electrode varies in width along a length defined from the proximal end to the intermediate portion, and
- wherein the proximal end of the electrode is fixed relative to the housing and the distal end of the electrode is freely longitudinally slidable within the housing toward a tip of the catheter away from the proximal end.
