Abstract

A device has a generator for generating low-frequency pulsed electric currents and a transmitter coil connected to the generator for applying electromagnetic fields to a body region of a living organism and is designed for transporting ions from intra-corporal electrolyte liquids of the living organism into and through surrounding vessel walls and membranes such that the transmitting energy is selected to such a high value that the energy induced within the electrolyte liquid is greater than a thermal energy and is within a cell-specific amplitude window. Pulsed currents generated within the transmitter coil by the generator have the following properties: a) a basic current pulse of a first duration consists of a square current and a superimposed current increasing according to an exponential function; b a pulse interval subsequent to the basic current pulse having a second duration that is at least equal to the first duration; c) a basic frequency of the basic current pulse with the pulse interval is 100 to 1000 Hz; d) an amplitude of a sequence of the basic current pulses is modulated with a frequency of 0.5 to 35 Hz to yield a modulation amplitude; e) the sequence of the basic c…
