Abstract
A positioning method for balloon coating by which the thickness, morphological form and the like of a drug in a coating formed on a balloon can be suitably set. This method is a positioning method for balloon coating for forming a coating layer containing a water-insoluble drug on an outer surface of a balloon of a balloon catheter. The positioning method includes a positioning step in which the dispensing tube is positioned in such a manner that a virtual position at which an opening portion would be located if the dispensing tube is assumed to be non-flexible is located within the range of 0 degrees to 40 degrees from the reference plane toward the rotating direction side of the balloon, in a region extending from the reference plane in a direction opposite to the discharge direction of the dispensing tube.
