ABSTRACT:
A lithotriptor is disclosed, which comprises an outer slender tube having an outside diameter small enough to be inserted into the organ growing a stone therein and an inner member disposed inside the outer slender tube. The inner member or the outer slender member incorporates therein an explosive layer or a gas-generating layer, ignition means for igniting the explosive layer or the gas-generating layer, and a closing member for preventing rearward advance of the gas evolved during the explosion of the explosive layer or the gas-generating layer. By the blasting of the explosive layer or the gas-generating layer, the outer slender tube or the inner member is caused to collide with the stone and crush it.
