Title:
BALLOON COATING METHOD, BALLOON ROTATION METHOD, AND BALLOON COATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/171252
Kind Code:
A1
Abstract:
Provided are: a balloon coating method which is capable of appropriately applying a coating liquid to the outer surface of a balloon, and which is capable of appropriately setting the morphotype or the like of a drug with which the balloon is to be coated; a balloon rotation method; and a balloon coating device. The balloon coating method for forming, on the outer surface of a balloon (30) of a balloon catheter (10), a coating layer (32) including a water-insoluble drug is provided with a step in which a dispensing tube (134) for supplying a coating liquid including a drug is moved relative to the balloon (30) in the axial direction (X) of the balloon (30), while the balloon (30) is being rotated around the axial centre (X) of the balloon (30) as a result of the application of rotational force with the same rotational frequency to both the base end side and the leading end side rather than an expanding area of the balloon (30) of the balloon catheter (10), to apply the coating liquid to the outer surface of the balloon (30).
