Abstract
A medical device has a rotatable drive shaft, a rotary body that 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, a switching portion whose distal end is disposed at a position protruding from the cutting edge, and a holding portion that holds the switching portion so as to move the switching portion on the same plane as the cutting edge or to a position away from the stenosed site beyond the cutting edge in accordance with a pushing force, when the switching portion is pushed against the stenosed site.
