Abstract
A therapeutic ultrasound energy delivery system includes a probe having a vibrational transducer. A restraint is disposed about the transducer in order to exert a compressive pre-stress on the transducer. The restraint inhibits tensile failure of the vibrational transducer at high acoustic output.
