Abstract
This disclosure relates generally to the field of devices and procedures for forming an opening between adjacent tissue structures. For example, in an embodiment, a system for forming an opening between body lumens may include a delivery catheter. A first access element may be configured to be positioned against a first body lumen disposed about a distal end of the catheter. A second access element having an outer diameter that substantially matches an outer diameter of the first access element may be disposed about the distal end of the catheter. The second access element may be configured to be positioned against a second body lumen and axially aligned with the first access element. A filament may be electrically coupled to one or both of the first and second access element.
