Abstract
A metal probe for intracorporeal shock wave lithotripsy has a point at its distal end with one or several lateral notches next to the probe end. These notches secure a calculus laterally against an adjacent duct wall and thus prevent it from bursting when it is crushed.
Claims9
Metal probe adapted to be introduced into the lumen of an endoscope for use in intracorporeal lithotripsy, and whereon a probe tip forming a distal end of the probe is used for crushing calculi by shock waves which are transferred by means of the probe and which result from an impact energy transferred to the proximal end of the probe for transmission, characterised in that said probe tip is provided with at least one notch in the vicinity of the probe end, which is configured for a laterally directed fixation of a calculus to be crushed against a joining duct wall.
