    摘要： A method and a system for destruction of an undesirable formation in a mammalian body are described. The invention is based on inserting a probe into mammalian body; said probe is electrically connectable to a control unit and upon bringing the probe in physical contact with the formation supplying pulses of energy from the control unit to the probe in order to destroy the formation. The invention further comprises counting amount of pulses being supplied to the probe and establishing a remaining service life of the probe by subtracting the amount of pulses being supplied to the probe from an amount of pulses corresponding to initial service life of the probe. The treatment session is automatically terminates as soon as amount of pulses being supplied to the probe approaches at least a fraction of the established remaining service life of the probe. The established remaining service life of the probe is stored for new treatment session. Delivery of pulses automatically terminates when the remaining service life is exhausted and use of such probe becomes impossible.

    摘要： Fluid is pressurized and supplied to a fluid chamber with a fluid pressurizing and supplying unit. The pressurized fluid within the fluid chamber is ejected through an injection nozzle by reduction of the volume of the fluid chamber caused by applying a driving voltage to a volume varying unit. In applying the driving voltage to the volume varying unit, the effect imposed on fluid injection by pressure fluctuations of the fluid pressurized and supplied to the fluid chamber is compensated by changing the voltage waveform of the driving voltage. When the pressure of the supply flow amount is decreased to a pressure lower than a predetermined pressure, the time intervals of the driving waveform are corrected. The maneuverability of a fluid injection device does not deteriorate even when the pressure of the fluid pressurized and supplied to the fluid chamber fluctuates.
