Abstract
A vascular stent-graft system comprises a stent-graft with an expandable tip and a restraining member disposed about at least a portion of that tip. The restraining member constrains expansion of the tip, even absent contact with a delivery device by which the stent-graft is deployed. Thus, unlike prior art designs, the tip can be partially positioned and at least temporarily freed from the grasp of a deployment device without risk that the tip will be prematurely expand into a potentially undesirable fit in the aorta.
