Abstract:
1. A stimulation system comprising an implantable control device and an implantable electrode device for generating electrical impulses, which can be supplied with energy and controlled by the control device in an exclusively wireless manner by means of a time-varying magnetic field, the control device being configured such that the field strength of the magnetic field, at least during switch-on times, has a substantially ramp- or sawtooth-shaped time profile or is bipolar or pulsed; and wherein the stimulation system is configured in such a manner that in the switched-on state the magnetic field is formed by a plurality of unipolar or bipolar magnetic field pulses and/or that the respective switch-on duration of the magnetic field controls or determines the length of each electrical impulse of a stimulation generated by the electrode device and/or the magnetic field is utilized for energy recovery.
