Abstract
An extracorporeal lithotripter has an ultrasound transducer mounted within the lithotripter reflector. The reflector and transducer are oriented downwardly, and a housing surrounds the transducer to protect the transducer from shockwaves generated within the reflector at the first focus point thereof. The housing opens downwardly, and a sleeve encircles the lower portion of the housing and extends below the housing. A conduit is connected to the sleeve to provide pressure less than atmospheric in said sleeve to effect filling of said sleeve with water for operation of the ultrasound transducer. The conduit alternatively and selectively effects filling of the sleeve with gas to protect against reflected shockwaves from below that might otherwise damage the transducer.
