  • Publication number: 20120253455
    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.
