摘要:
Provided are: a stent production method with which drug separation or exfoliation caused by stress concentration or strain accompanying expansion and deformation of the stent is inhibited and with which yield during production and drug effect uniformity are yet further improved and a coating device. The present invention is provided with an uncoated portion formation step in which when a nozzle (266) reaches a curved portion (31) the nozzle passes over the curved portion and moves towards a main strut portion (32, 33) and as a result the coating of the curved portion with a drug is inhibited. In the uncoated portion formation step during a time period in which the nozzle (266) is passing over the curved portion a deposition amount of a coating liquid (a) deposited on the nozzle is reduced.
