Abstract:
1. A neurostimulation system, comprising: an electrical neurostimulator; a plurality of electrodes coupled to the electrical neurostimulator; and external control device configured for defining a target current source multipole relative to the plurality of electrodes, emulating the target multipole by defining an initial electrical current distribution for the electrodes, such that a first set of active electrodes respectively has electrical current values of a first polarity, and a second set of active electrodes respectively has electrical current values of a second polarity, comparing each of the electrical current values of the first polarity to a first threshold value, zeroing-out at least one of the electrodes in the first active electrode set based on the comparison, redistributing the electrical current value of each of the at least one zeroed-out electrode in the first active electrode set to remaining ones of the electrodes in the first active electrode set to define a new electrical current distribution for the electrodes, and instructing the electrical neurostimulator to convey electrical current to the plurality of electrodes in accordance with the new electrical current distribution.
