Abstract

A balloon catheter is disclosed having a balloon at a distal portion of a catheter shaft and on a surface of the balloon are elongate bodies which are crystals of a water-insoluble drug having independent long axes. The balloon in a deflated state has a plurality of wing portions in a circumferential direction of the balloon, and a circumferential surface portion along a circumferential direction of the catheter shaft, the plurality of wing portions being folded along the circumferential direction of the balloon. A surface of the circumferential surface portion which faces the plurality of wing portions that are folded has a region in which tip portions are not in contact with the surface of the balloon or with other elongate bodies, and a surface which faces the plurality of wing portions that are folded which faces an outer circumferential side has a region in which the tip portions are in contact with the surface of the balloon or with the other elongate bodies.
