1. An implantable medical device for delivering neurostimulation, comprising:
a pulse generator;
a number N of electrodes, wherein N is equal to or larger than 3, wherein said pulse generator is configured to deliver via each N electrode a set of pulses with a frequency f and including a therapeutic electric pulse and a number of N−1 charge balancing electric pulses, wherein the charge balancing electric pulses of the electrode each have a polarity being opposite a polarity of the therapeutic electric pulse of the electrode, wherein a current of the therapeutic electric pulse is equal to a sum of currents of the charge balancing electric pulses;
wherein the implantable medical device is configured to deliver the therapeutic electric pulse to at least one of said N electrodes and to deliver a charge balancing electric pulse in all of said other N−1 electrodes at a time of delivery of the therapeutic electric pulse to the at least one of said N electrodes; and
said pulse generator is configured to deliver the charge balancing electric pulses with varied current amplitudes.
