Patent ID: 8777963

Claim:
A method for treatment of an undesirable formation within a mammalian body by electro-impulse destruction of the formation caused by a high voltage pulses applied to the formation, said method comprising: a) providing a treatment probe for insertion within a mammalian body, said treatment probe having a working head, said treatment probe is electrically connectable to a control unit, which is capable to generate high voltage pulses, b) bringing a forwardmost end of the working head in physical contact with the formation, c) calculating an initial service life of the treatment probe, said initial service life corresponding to energy and frequency of high voltage pulses which are selected for a current treatment session, d) generating high voltage pulses selected for the current treatment session, e) supplying of the high voltage pulses to the head via a coaxial cable and releasing them from the forwardmost end immediately in the formation, e) counting an amount of the high voltage pulses released during the current treatment session, f) calculating a remaining service life of the treatment probe using the initial service life and the amount of pulses counted during the current treatment session, g) terminating the current treatment session as soon as the remaining service life approaches a preset limit, and h) storing the remaining service life, wherein the initial service life is expressed by a criterion taking into consideration the probe's diameter as well as energy and frequency of the high voltage pulses to be supplied during the current treatment session.
