Abstract
A catheter having opposed tissue contacting surfaces for creating an anastomosis between two blood vessels is utilized to facilitate a method for percutaneously placing a biologic graft at a procedural site. The method may comprise steps of inserting a guidewire into a blood vessel, placing a sheath over the guidewire, advancing a biologic graft over the guidewire into the blood vessel at a biologic graft attachment site, advancing a catheter over the guidewire, pushing a distal tip of the catheter through the biologic graft, a vessel wall of the blood vessel, and into a lumen of the blood vessel, and creating an anastomosis between the biologic graft and the blood vessel by activating the catheter to apply energy to the vessel wall and to a wall of the biologic graft.
