Estimating the term…
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.
A manufacturing method of a stent that has an annular body configured to include a waved strut which at least has first and second main strut portions to be coated with a drug and a bending portion formed between the first and second main strut portions, the method comprising:
A coating device for coating, with a drug, a stent that has an annular body configured to include a waved strut which at least has first and second main strut portions to be coated with the drug and a bending portion formed between the first and second main strut portions, comprising:
