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; memory storing a first set of variable values defining a first spatial relationship between a central ideal pole of a first polarity and the plurality of electrodes, a second set of variable values defining a second spatial relationship respectively between four ideal poles of a second polarity and the first ideal pole, and a third set of variable values defining relative intensities between the four ideal poles; and control circuitry configured for modifying at least one of the first set of variable values, the second set of variable values, and the third set of variable values in response to the control signals, and generating, based on the modification, stimulation parameter values defining relative amplitude values for the plurality of electrodes that emulate the ideal poles, and instructing the electrical neurostimulator to convey electrical energy to the plurality of electrodes in accordance with the plurality of stimulation parameter values.
