摘要:A stent and method of its use, the stent in its expanded configuration, exhibitingvarying outward radial force along its length. In use, the expanded stent is of a taperedconfiguration which provides greater force in vessel regions requiring greater force andless force in regions requiring less. In particular the stent is useful in the ostium regionsand at areas of bifurcation in vessels. Varying force over the length of the stent isachieved by varying the number of elements, the density of elements, the thickness ofthe elements making up the stent body, and maintaining a substantially metal to arteryratio in the expanded stent over its length.
