Abstract:
1. A system for an electrical neurostimulator coupled to a plurality of electrodes, comprising: a user-controlled input device configured for generating control signals; and control circuitry configured for defining at least one ideal multipole configuration relative to the plurality of electrodes in response to the control signals, each of the at least one ideal multipole configuration having at least two poles aligned along a pole axis, the control circuitry, for each of the at least one ideal multipole configuration, being further configured for, designating at least one of the electrodes as a reference electrode, estimating an effective electrode separation at each of the at least one reference electrode, defining a spacing between the at least two poles based on the estimated effective electrode separation at each of the at least one reference electrode, generating at least one stimulation parameter set respectively corresponding to the at least one ideal multipole configuration, each of the at least one stimulation parameter set defining relative amplitude values for the plurality of electrodes that emulate the respective ideal multipole configuration, and instructing the electrical neurostimulator to convey electrical energy to the plurality of electrodes in accordance with the at least one stimulation parameter set.
