Disclosed is a method and apparatus for treating bifurcations of the vascular system, such as abdominal aneurysms at the bifurcation of the aorta and iliac arteries. A tubular implant having a proximal section, a distal section and a hinged connection therebetween is positioned across the bifurcation such that the proximal section extends into a first iliac and the distal section extends into the second iliac. The proximal and distal iliac sections are both advanced superiorly, causing the implant to fold at the hinge and advance across the aneurysm into the aorta. In one implementation, restraining sleeves are thereafter removed and the implant self expands to place aorta in fluid communication with the first and second iliacs, bypassing the bifurcation. Deployment catheters are also disclosed. |
