Abstract
A medical device is capable of aspirating an object in a body lumen, while preventing the retention of the object therein, and effectively discharging the object. The medical device includes: a rotatable drive shaft having a lumen; a cutting portion fixed to a distal portion of the drive shaft to cut the object; and a housing that contains a proximal portion of the drive shaft and has a discharge port through which the cut object is discharged. The drive shaft has a proximal opening portion that extends around a portion of a circumference of the drive shaft to expose a discharge opening. The discharge port includes a discharge hole through which the cut object discharged through the discharge opening of the proximal opening portion is discharged from the housing, and a guide surface that protrudes toward the proximal opening portion to guide the cut object into the discharge hole.
