Abstract
A medical device that removes an object from a biological lumen, includes a rotatable drive shaft having a lumen through which the object passes, a cutting unit disposed at a distal end of the drive shaft and by which the object is cut, a proximal shaft to be rotated by a rotary force, a connection unit connecting the proximal shaft and the drive shaft and by which the rotary force is transmitted to the drive shaft, and a housing that houses the connection unit and includes a discharge port communicating with the lumen via the connection unit and through which the cut object is discharged. The connection unit includes a surface that faces a proximal end of the drive shaft and prevents the object that passed through the lumen and is to be discharged from being retained in the connection unit along a rotation axis thereof.
