Sonographic Piezoelectric Lithotripsy: More Bang for your Buck
The four major components required in any lithotripter are an energy source to generate the shock wave, a focusing device to focus the shock wave toward the focal point, a coupling medium to couple the shock wave to the patient, and a stone localization system to allow the focal point of the shock wave to be aligned precisely on the stone. The development of second-generation lithotripters has resulted in modifications of these four lithotripsy components. All second-generation machines have done away with the large water bath first used by Dornier in the HM3 device, and all new models utilize either a fluid-filled membrane or a small pool of degassed water.
