Abstract
A medical device that reduces stress concentration on a part of a drive shaft and has stable rotation and durability. The medical device that removes an object in a body lumen includes: a rotatable drive shaft; a driving portion configured to apply torque to a proximal portion of the drive shaft and having a specified rated rotation direction; a cutting portion fixed to a distal portion of the drive shaft and configured to cut the object; an outer tubular shaft rotatably accommodating the drive shaft, in which the drive shaft includes a proximal coil and a distal coil disposed on a distal side with respect to the proximal coil, and the distal coil is more deformable in a radial direction than the proximal coil by receiving load torque while the drive shaft is rotating in the rated rotation direction.
