A manufacturing method of a stent is disclosed which prevents a drug from being peeled off or separated due to stress concentration or distortion resulting from the expanding deformation of the stent so that the drug is further uniformly effective and further improved yields are expected when the stent is manufactured, and a coating device. The method has a non-coating portion forming process of preventing a bending portion from being coated with the drug by causing a nozzle to go past the bending portion when the nozzle reaches the bending portion and to move toward main strut portions. In the non-coating portion forming process, an adhesion amount of a coating solution is reduced while the nozzle is going past the bending portion.

Manufacturing method of stent and coating device

A stent able to minimize occurrences of strain and stress concentration in a drug coat layer upon expansive deformation of the stent in a radial direction to avoid the possibility of the drug separating from the stent, includes a stent body and a drug coating layer coated on the outside surface of the stent body so that the thickness of the drug coating layer gradually decreases toward a bent portion of the stent.

Stent with drug coat layer

Stent with drug coat layer including a gradual stepwise decrease portion

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.
