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.
