1. An apparatus for reducing subcutaneous fat deposits by electroporation comprising: an applicator comprising sets of needle electrodes adapted for penetrating the skin of a patient and applying a high amplitude pulsed electric field to the area of the subcutaneous volume of fat tissue to be treated by electroporation; a generator of high voltage pulses for applying pulsed electric field to the electrodes, said pulses generating an electric field above the upper electroporation limit for subcutaneous fat cells in the volume of subcutaneous fat tissue to be treated; and connectors connecting said generator of high voltage electrical pulses with corresponding needle electrodes placed under the skin.
