System and method for choosing electrodes in an implanted stimulator device
First Claim
1. A method of using a plurality of electrodes of a stimulator device implanted in a patient, the method comprising:
- providing a stimulator device comprising a plurality of electrodes, wherein the stimulator device is implanted in a patient;
taking a first type of measurement for each of the plurality of electrodes of the stimulator device;
taking a second different type of measurement for each of the plurality of electrodes of the stimulator device, wherein the measurements are indicative of the ability of the respective electrode if activated to provide useful therapy to the patient in which the stimulator device is implanted;
applying a first weight to the first type of measurement to respectively arrive at first weighted measurements for the respective electrodes;
applying a second weight to the second type of measurement to respectively arrive at second weighted measurements for the respective electrodes;
computing a function of the first and second weighted measurements to arrive at a value;
using the value to determine a subset of the electrodes; and
activating at least one electrode of the subset of the electrodes to deliver therapy to the patient.

Abstract
A method of selecting a subset of electrodes in a stimulator device implanted in a patient for further clinical evaluation is disclosed. The method comprises measuring at least first and second measurement for each of the plurality of electrodes that are indicative of the ability of the electrode if activated to provide useful therapy to the patient in which the stimulator device is implanted A weight is then determined for each of the measurements. The weight is then applied to each electrode measurement, which measurement may be normalized, and the weighted measurements for each electrode are preferably summed to arrive at a value which itself is indicative of a particular electrode'"'"'s ability to provide useful therapy to the patient. These values can then be used to determine a subset of the electrodes useful for further clinical evaluation in the patient, which improved the accuracy and speeding determining appropriate patient therapy.
