1. A method of placing an arteriovenous graft in a patient, comprising:
performing a blunt dissection between two incisions;
placing a first sheath between the two incisions;
backloading a first guidewire through the first sheath;
inserting a second guidewire into a blood vessel;
placing a second tear-away sheath over the second guidewire;
advancing a biologic graft over the second guidewire into the blood vessel at a biologic graft attachment site;
advancing a catheter over the second guidewire; and
creating an anastomosis between the biologic graft and the blood vessel by activating the catheter to apply energy to a vessel wall of the blood vessel and to a wall of the biologic graft.
