Abstract:
A stent includes a stent body in which struts are joined mutually while intersecting and which is formed tubularly as a whole, and a drug coat layer on the outer surface of the struts. The strut has a bend which is deformed as the stent body expands/contracts in the radial direction, and the drug coat layer with which the bend is coated is formed in such a manner that the drug coat layer is mountain-shaped in a cross-section perpendicular to the axis of the strut and the ridgeline of the mountain shape extends in a wavy shape along the longitudinal direction of the strut. The drug coat layer deforms relatively easily without using plasticizer as the stent deforms and is not so susceptible to causing problems such as peeling, destruction, damage or falling off of the drug coat later.
