Abstract
A dilatation catheter has a tubular proximal shaft having relatively high rigidity, a tubular distal shaft having rigidity lower than that of the proximal shaft, a tubular intermediate section interposed between the proximal shaft and the distal shaft, a hub mounted on the proximal end portion of the proximal shaft, a balloon arranged on the distal end portion of the distal shaft so as to be in fluid communication with the distal shaft, and an inner shaft into which a guide wire can be inserted. The distal end portion of the proximal shaft can be inserted into the intermediate section to form an insertion portion having a spiral slit.
