Abstract
A balloon catheter by which a drug can be effectively delivered to living body tissue and a method of manufacturing the balloon catheter, and a treatment method. The balloon catheter is provided on an outer surface of a balloon with a plurality of elongate bodies which are independent crystals of a water-insoluble drug that extend in an elongate form. The elongate bodies have long axes extending in directions along the outer surface of the balloon when the balloon is in a deflated state. Deformation, when the balloon is inflated from the deflated state, of portions on an outer surface side of the balloon to which end portions of the elongate bodies are fixed causes a force to act on the elongate bodies such that the long axes of the elongate bodies approach perpendicularity to the outer surface of the balloon.
