Abstract (en)
Kidney stones are disintegrated by extracorporeal apparatus generating shock waves. A reflector (12) open at one end, has a liquid such as water therein and a resilient diaphragm (14) across the open end of the reflector. A spark gap (26) is provided in the reflector, and a spark across this gap generates a shock wave and produces gas in the liquid. A flexible enclosure (38) within the reflector about the spark gap isolates the spark gap from most of the liquid in the reflector. Gas formed as an incident to discharging a spark across the gap is removed from this enclosure.
