Abstract
A method and device for endoluminally bypassing blood flow through an aneurysm in the vicinity of a branched blood vessel, having a main branch, a first branch, and a second branch. The method comprises steps of: advancing a distal end of a separable guide wire into the first branch, through the main branch, and out of the second branch; disposing a split-tube bifurcated graft, having a split in the middle and a middle portion that is tapered outwardly, about the guide wire; advancing said graft into the first branch, through the main branch, and out of the second branch; disposing stents about the guide wire and within the graft; advancing said stents simultaneously into the first and second branches until said stents stop against the guide wire; moving the graft-stent-guide wire assembly towards the cephalic portion of the aneurysm; deploying the stents; and finally removing the guide wire, which has a first portion and a second portion, from the patient by first removing a locking wire disposed within the guide wire and then by pulling the first and second portions apart simultaneously.
