Claim Text:
1. An external control device for use with a neurostimulation system having a plurality of electrodes capable of conveying an electrical stimulation field into tissue in which the electrodes are implanted, comprising: a user interface including a mode selection control element and an electrical stimulation field modification control element, the mode selection control element configured for receiving a selection between an electrical stimulation field displacement mode and an electrical stimulation field shaping mode, the electrical stimulation field modification control element configured to allow for displacement of a locus of the electrical stimulation field relative to the electrodes when the electrical stimulation field displacement mode is selected, and to allow for shaping of the electrical stimulation field about its locus by adjusting a distribution of an electrical current over the electrodes when the electrical stimulation field shaping mode is selected; a processor configured for placing the electrical stimulation field modification control element in either the electrical stimulation field displacement mode or the electrical stimulation field shaping mode based on the received selection, for generating a first set of stimulation parameters designed to displace the locus of the electrical stimulation field when the electrical stimulation field modification control element is placed in the electrical stimulation field displacement mode, and for generating a second set of stimulation parameters designed to shape the electrical stimulation field about its locus when the electrical stimulation field modification control element is placed in the electrical stimulation field shaping mode; output circuitry configured for transmitting the first and second sets of stimulation parameters to the neurostimulation system; and a housing containing the user interface, the processor, and the output circuitry.
