摘要:
An endovascular prosthesis is disclosed that includes a tubular graft and a radiopaque marker attached to envelop or enfold an edge of the tubular graft. A first segment of the radiopaque marker extends against an interior surface of the tubular graft and a second segment of the radiopaque marker extends against an exterior surface of the tubular graft such that the first and second segments sandwich or straddle the edge of the tubular graft. The radiopaque marker may include a living hinge that demarcates the first and second segments and aligns with the tubular graft edge when the radiopaque marker is attached thereto. The radiopaque marker may have a substantially U shape with the first and second segments biased toward each other by an end segment such that the end segment aligns with the tubular graft edge when the radiopaque marker is attached thereto.
