Electrical stimulation based on phase response mapping
First Claim
1. A method comprising:
- delivering a plurality of electrical stimulation pulses at a plurality of different phases relative to an oscillating neurological signal of a patient;
measuring a response in the oscillating neurological signal for each delivery of an electrical stimulation pulse of the plurality of electrical stimulation pulses;
determining a phase response of the patient based on the measured responses; and
delivering a therapy to the patient based on the determined phase response of the patient, wherein each of measuring and determining are performed at least in part by circuitry.

Abstract
This disclosure describes techniques for delivering electrical stimulation at one or more phases relative to an ongoing oscillating signal in a patient, and then mapping the response to the oscillating signal. The techniques may reduce or eliminate the oscillating signal. In one example, the disclosure is directed to a method that includes delivering a set of first electrical stimulation at a plurality of phases relative to an oscillating signal, measuring a response in the oscillating signal to the set of first electrical stimulation after delivering electrical stimulation at each respective phase of the plurality of phases, determining a phase at which to deliver second electrical stimulation based on the measured responses, and delivering the second electrical stimulation to the patient at the determined phase to produce a therapeutic effect.
