Abstract

A lithotripsy system having improved localization and shock wave generation apparatus. The lithotripsy system comprises an x-ray prelocation system allowing for initial localization of a calulus within a body of a patient. Following the initial localization step, the patient is moved utilizing a sliding table top into a treatment position. A high power shock-wave generation device is provided for generating shock waves for disintegrating the calculus. The lithotripsy system further provides for an ultrasonic monitoring device, coupled with the high power shock wave generation device, allowing for real-time localization of the calculi. The disclosed system utilizes, as part of the shock wave generation device, a piezoelectric transducer, an acoustical lens coupled with the transducer and a means for coupling the transducer to receive voltage from a high power voltage means.
