1. A system for forming an opening between body lumens, the system comprising:
a delivery catheter;
a first access element encircling an exterior surface of a distal end of the delivery catheter and configured to be positioned against a first body lumen;
a second access element encircling an exterior surface of the distal end of the delivery catheter and having an outer diameter that substantially matches an outer diameter of the first access element, the second access element configured to be positioned against a second body lumen and axially aligned with the first access element; and
a filament electrically coupled to the second access element.
