Low profile improved radiopacity intraluminal medical device
First Claim
Patent Images
1. An intraluminal medical device comprising:
- a substantially tubular member having open ends, and a first diameter for insertion into a lumen of a vessel and a second diameter for anchoring in the lumen of the vessel; and
at least one marker connected to at least one end of the substantially tubular member, the at least one marker comprising a marker housing having a substantially circular shape with flattened sections and a marker insert, both having a radius of curvature equal to the radius of curvature of the substantially tubular member.

Abstract
A stent or other intraluminal medical device having markers formed from housings integral with the stent and marker inserts having a higher radiopacity than the stent provides for more precise placement and post-procedural visualization in a vessel, by increasing the radiopacity of the stent under X-ray fluoroscopy. The housings are formed integral to the stent and the marker inserts are made from a material close in the galvanic series to the stent material and sized to substantially minimize the effect of galvanic corrosion. The housings are also shaped to minimize their impact on the overall profile of the stent.
