Abstract
A method of creating an AV fistula between adjacent first and second vessels includes inserting a guidewire from the first vessel into the second vessel. Inserting a catheter including a proximal member and a distal member over the guidewire such that a distal tip of the distal member comes into contact with a selected anastomosis site. Moving the distal member and the proximal member together to clamp tissue surrounding the aperture between the distal face of the proximal member and a proximal face on the distal member. Applying energy to an active heating member on the proximal member to cut and form the aperture, and to weld the edges thereof in order to create a desired fistula between the two vessels. Using a passive heating member disposed on the distal member to create a heating gradient across a tissue contacting surface of the distal member.
