    • A stent is adapted to be implanted in a side branch at a bifurcation from a main blood vessel in a patient's body, wherein the bifurcation from the main vessel is skewed, the stent having open ends, of which one is angled at a skew to the longitudinal axis of the stent to match the angulation of the side branch, whereby to afford substantially complete coverage of the inner wall of the side branch at the bifurcation, when the stent is implanted. The angle of the skew is about 45null, which gives the stent a short side and a long side connected together in a plane along the wall of the stent at that end end; and the other end of the stent is at a right angle to the longitudinal axis of the stent. At least one of the short side and the long side has a viewable marker to facilitate proper orientation of the stent during implant thereof. A drug-eluting coating is provided on the surface of the stent to inhibit restenosis of the side branch when the stent is implanted therein.
    • 支架适于从患者体内的主血管以分叉方式植入在侧支中,其中来自主血管的分叉是偏斜的,所述支架具有开口端,其中一个与所述主支管的歪斜成角度 支架的纵向轴线以匹配侧分支的角度,从而当植入支架时,在分叉处提供基本上完全覆盖侧支的内壁。 歪斜角度约为45°,这使得支架在短端和长边在连接在该端部的支架壁的平面内连接在一起; 并且支架的另一端与支架的纵向轴线成直角。 短侧和长边中的至少一个具有可视标记,以便于在其植入期间支架的适当取向。 当支架植入时,在支架的表面上设置药物洗脱涂层以抑制侧支的再狭窄。
