Abstract

An improved shockwave lithotripsy system includes a movable patient support carriage having a shock wave generator and focussing device mounted thereto, along with an indexing reference. An ultrasonic oscillator is also attached to a mounting arm arrangement mounted in turn to the support carriage and allowing for three dimensional adjustment of the oscillator relative to a patient on the carriage, the mounting arrangement having an additional indexing reference such that after a concrement internal to the patient is located using the ultrasonic oscillator, the shock wave generator may be brought into focus on the concrement by bringing the indexing references into registry.
