Abstract

A balloon coating method is disclosed for forming a coating layer containing a water-insoluble drug on an outer surface of a balloon of a balloon catheter. The balloon coating method includes an application step in which, where a pipe-shaped dispensing tube formed from a polyolefin for supplying a coating solution containing the water-insoluble drug and a solvent is formed at its end portion with an opening portion for discharging the coating solution therethrough and when the end portion side of the dispensing tube is placed in contact with the outer surface of the balloon while the balloon is rotated about an axis of the balloon, the coating solution is discharged through the opening portion and applied to the outer surface of the balloon while the dispensing tube is moved relative to the balloon in an axial direction of the balloon.
