Abstract
An endovascular bypass graft includes a tubular member, a first expandable mesh stent attached to one end of the tubular member, and a second expandable mesh stent attached to an opposite end of the tubular member. The second stent is provided with a plurality of fenestrations. The graft is inserted into a principal blood vessel such as the aorta and positioned in the vessel so that the fenestrations are aligned with junctions with ancillary blood vessels. The graft is attached to the principal blood vessel so that the fenestrations remain aligned with the respective junctions, thereby allowing blood flow between the principal vessel and the auxiliary vessels through the respective junctions upon completion of the bypass operation.
