Mehrschichtiger Metallstent

摘要

Coated stents for increased radiopacity. In one embodiment, the present invention includes a stent in the form of a tubular member comprising struts of a first material, and a first coating on the tubular member. The first coating substantially covers the tubular member and is substantially uniform in thickness. The first coating comprises a second material that is more radiopaque than the first material. In another embodiment, the stent further comprises a second coating between the tubular member and the first coating, wherein the second coating covers only a portion of the tubular member. In yet another embodiment, the stent is a coated bifurcated stent for positioning in a bifurcated body lumen.
