Claim 9:
10. A medical device for removing an object inside a biological lumen, comprising:
a drive shaft that is rotatable about a rotation axis;
a cutting portion fixed to a distal portion of the drive shaft and configured to cut the object;
a first housing that accommodates the drive shaft to be rotatable relative to the first housing;
a second housing located on a distal side of the first housing and rotatable with respect to the first housing around the rotation axis, wherein the drive shaft is rotatable relative to the second housing; and
a support portion that supports the first housing and the second housing, wherein the drive shaft is rotatable relative to the support portion,
wherein the first housing and the second housing, or the first housing and the support portion are configured to come into slidable contact with each other so that relative rotation is restricted,
wherein the support portion supports the first housing to be rotatable around the rotation axis, and
wherein the support portion restricts a relative inclination of the first housing and the second housing in a direction intersecting with the rotation axis.
