NEUROSTIMULATION SYSTEM FOR SELECTIVELY ESTIMATING VOLUME OF ACTIVATION AND PROVIDING THERAPY
First Claim
1. An external control device for use with a neurostimulator coupled to a plurality of electrodes capable of conveying electrical stimulation energy into tissue in which the electrodes are implanted, comprising:
- output circuitry configured for transmitting sets of stimulation parameters to the neurostimulator;
a user interface including a display device and at least a first control element configured to be actuated to selectively place the external control device between a first mode and a second mode; and
a processor, when the external control device is in the first mode, configured for simulating a volume of tissue activation for each of a first one or more candidate stimulation parameter sets, while preventing the output circuitry from transmitting the first one or more of candidate stimulation parameter sets to the neurostimulator, and when the external control device is in the second mode, configured for allowing the output circuitry to transmit a second one or more of candidate stimulation parameter sets to the neurostimulator.

Abstract
An external control device, neurostimulation system, and method of programming a neurostimulator. A volume of tissue activation for each of a first one or more candidate stimulation parameter sets is simulated without conveying electrical stimulation energy into the tissue. One of the first candidate stimulation parameter set(s) is selected based on each simulated volume of tissue activation. Electrical stimulation energy is conveyed into the tissue in accordance with a second one or more candidate stimulation parameter sets, wherein the initial one of the second candidate stimulation parameter set(s) is the selected one of the first candidate stimulation parameter set(s). One of the second candidate stimulation parameter set(s) is selected based on a therapeutic efficacy of the electrical stimulation energy conveyed into the tissue. The neurostimulator is programmed with the selected one of the second candidate stimulation parameter set(s).
