Abstract
A medical device has a rotatable drive shaft, a rotary body whose distal end includes a cutting edge for applying a cutting force to a stenosed site, and that is disposed on a distal side of the drive shaft so as to be rotated in conjunction with rotation of the drive shaft, and a distal member disposed in the rotary body. The distal member has a support portion extending to a distal side beyond a distal end of the rotary body, and configured to be capable of supporting the rotary body with respect to a blood vessel. The support portion is configured so that a distance from the rotary body is variable in a first direction (height direction) in which the rotary body is moved close to the stenosed site.
