1. An endovascular prosthesis comprising:
a tubular graft of a graft material having a proximal end, a distal end, an interior surface and an exterior surface; and a radiopaque marker having a first segment and a second segment with a living hinge therebetween, wherein the living hinge is a thinned portion between the first and second segments, the radiopaque marker being attached to one of the proximal and distal ends of the tubular graft such that the radiopaque marker straddles a portion of a true edge of the graft material such that the living hinge lays along the true edge of the graft material with the first segment of the radiopaque marker being positioned to extend from the living hinge against the interior surface of the tubular graft and the second segment of the radiopaque marker being positioned to extend from the living hinge against the exterior surface of the tubular graft, wherein the living hinge permits the first and second segments to swing relative to each other when the radiopaque marker is unattached from the tubular graft. |
