Disclosed is a method and apparatus for treating bifurcations of the vascula r system, such as abdominal aneurysms at the bifurcation of the aorta and ilia c arteries. A tubular implant (42) having a proximal section (44A), a distal section (44B) and a hinged connection (54) therebetween is positioned across the bifurcation such that the proximal section extends into a first iliac an d 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 (74A, 74B) are thereafter removed and th e implant self expands to place aorta in fluid communication with the first an d second iliacs, bypassing the bifurcation. Deployment catheters (70) are also disclosed. |
