  • Patent number: 7264633
    Abstract: A stent or other intraluminal medical device may be constructed utilizing a series of anvil bridges interposed between a series of fixed bridges to reduce the likelihood of deformation during stent loading and stent deployment without sacrificing overall stent flexibility. The stent comprises a plurality of hoops interconnected by a plurality of fixed bridges. The stent also comprises a plurality of anvil bridges, which transmit forces only when the stent is subjected to compressive axial loading. The stent may also comprise markers formed from housings integral with the stent and marker inserts having a higher radiopacity than the stent. This design 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.
