Apparatus for cleaning a vessel having a stenosis therein comprising first and second balloon catheters. Balloons are disposed on opposite sides of the stenosis in the vessel and form a closed chamber in the vessel. A therapeutic catheter having a distal extremity is disposed in the chamber. Irrigation liquid is supplied to the chamber and liquid is aspirated from the chamber to form an aspirate. The distal extremity of the therapeutic catheter is moved to cause the material forming the stenosis to be removed from the wall of the vessel and to be broken into particles which are removed with the aspirate.
