This ultrasonic device has a wire for removing the plaque, a sheath around the wire for minimizing transverse displacement during cavitation; a handpiece having a portion joined to the wire at one end, and a transducer in the handpiece for vibrating the wire axially. It may also have a pips fitting having an opening for a syringe for fluid under pressure for a passageway between the wire and sheath.
