Abstract
An apparatus for disintegrating calculuses of the type found in a human body, transmits a shockwave through a container filled with a liquid medium, into the body. The apparatus comprises a tank which stores the liquid, a sensor for detecting pressure in the container, and a liquid control system. When pressure exceeds a preset value, the control system transports liquid from the container to the tank until the pressure falls below the preset value.
