First Claim
1. A method for delivering electrical stimulation therapy to a patient, the method comprising:
- delivering an electrical stimulation therapy to the patient via a medical device, the electrical stimulation therapy comprising a first electrical stimulation pulse delivered to the patient via a first electrode and a second electrical stimulation pulse delivered to the patient via a second electrode, wherein the first electrical stimulation pulse and second electrical stimulation pulse have a same polarity and are delivered as paired pulses with respect to each other such that a first charge of the first electrical stimulation pulse and a second charge of the second stimulation pulse build on each other to generate a combined charge in tissue of the patient, and the combined charge of the first electrical stimulation pulse and the second electrical stimulation pulse evoke a compound action potential within the patient;
sensing, at each of a plurality of sensing locations, a respective magnitude of the compound action potential evoked by the combined charge of the first electrical stimulation pulse and the second electrical stimulation pulse;
comparing the sensed respective magnitudes to a desired magnitude for each location of the plurality of sensing locations; and
adjusting, based on the comparison of the sensed respective magnitudes to a desired magnitude for each location of the plurality of sensing locations, one or more parameters of the electrical stimulation therapy to move a region of tissue activated by the compound action potential evoked by the combined charge of the first electrical stimulation pulse and the second electrical stimulation pulse.
