Abstract
A connection is made between inner and outer conductors leading to electrodes to be used for the generation of shock waves for the contact free comminution of concrements (lithotripsy) whereby the inner conductor ends in a tip element and is surrounded by an electrically insulating synthetic sleeve, while the outer conductor is likewise provided with a tip element which is held by a cage that extends from the outer conductor proper; the outer conductor is provided with a plurality of annular grooves and as the metal sleeve is inductively heated synthetic material from an originally underformed insulating sleeve flows into the groove such that an axially immobile connection obtains between the thus inter connected conductors to, thereby, indirectly maintain the desired and gauged spacing between the electrode tip elements.
