High output therapeutic ultrasound transducer

摘要

A therapeutic ultrasound delivery system, comprising: a catheter body; a plurality of axially spaced-apart hollow cylindrical vibrational transducers disposed along a length of the catheter body; a first spring connector wrapped around the outer surfaces of the vibrational transducers, the first spring connector exerting an inward pre-stress on the outer surfaces of the vibrational transducers; and a second connector disposed in contact with the inner surfaces of the vibrational transducers.
