Abstract

A balloon coating method and a balloon coating apparatus are disclosed by which the thickness and/or morphological form of a drug in a coating formed on a balloon can be appropriately set. The balloon coating method can include moving a coating section for applying a coating liquid containing a drug relative to the balloon in the direction of an axis, while rotating the balloon about the axis of the balloon, thereby to apply the coating liquid to an outer surface of the balloon; detecting the distance of a dried part where the coating liquid applied to the outer surface of the balloon has been dried from the coating section; and controlling moving velocity of the coating section relative to the balloon in such a manner that the distance of the dried part from the coating section is maintained at a preliminarily set designated distance.
