Abstract

A percutaneous system for bypassing a restriction in an artery of a mammal having an aorta includes providing a graft having a body portion with a first end, a second end and a lumen therebetween. First and second expandable stents are provided at the first and second ends of the graft, respectively. Apertures are formed in the artery, distal of the restriction, and in the aorta and the graft is inserted between the apertures. At least a portion of the first stent is inserted through the aperture in the artery and the stent is deployed to connect the first end of the graft within the artery. The second stent is positioned such that a first expandable portion is outside the aorta and a second expandable portion is within the aorta. The first and second expandable portions of the second stent are expanded to have outer diameters at least as large as the aperture in the aorta to anchor the first end of the graft in the aorta such that the lumen in the graft communicates with the aorta and the artery.
