Implantable medical device with fenestration and radiopaque marker coils on stents

摘要

A fenestrated implantable medical device, such as a stent graft (10) is provided with a plurality of zigzag stents (12) of which two or more form fenestrations (34, 36) using part of the stents (12) as a support frame (30, 32) for the fenestrations (34, 36). The frames (30, 32) are preferably covered by radiopaque wire (44) coiled around the stent structures. The radiopaque coil (44) provides easy reference to the fenestrations (30, 32) for imaging purposes.
