1. A method for fragmenting of various calculi in a living body by intracorporeal lithotripsy treatment, during which a probe is brought to the calculus to be fragmented, said probe is provided with electrodes, connected to a means for generating of high voltage impulses, said impulses are supplied to the electrodes for igniting spark discharge between them and release of energy, causing fragmenting of the calculus, wherein the method comprises bringing of at least one of the electrodes in electrical contact immediate with the calculus so as to establish a discharge channel capable to create shock waves and stresses, which excess the strength of the calculus material.
