Patent ID: 11931581
Assignee: MEDTRONIC, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 20:
21. A system comprising:
an implantable medical device (IMD) comprising:
a plurality of electrodes disposed on a lead;
stimulation circuitry;
sensing circuitry configured to:
sense, via the plurality of electrodes, a first plurality of electrical signals at each position of a plurality of different positions of a brain of the patient, wherein the first plurality of electrical signals result from a source of oscillations within the brain of the patient, and wherein each position of the plurality of different positions corresponds to a different respective sensing electrode combination; and
sense, via the plurality of electrodes, a second plurality of electrical signals at each position of at least a subset of the plurality of different positions of the brain of the patient, the subset comprising two or more positions of the plurality of different positions of the brain, wherein the second plurality of electrical signals are responsive to delivery, by the stimulation circuitry, of electrical stimulation according to each of a plurality of different values of at least one therapy parameter to each position of the at least the subset of the plurality of different positions, and wherein each position of at least the subset of the plurality of different positions corresponds to the different respective sensing electrode combination; and

an external programmer comprising processing circuitry configured to:
determine, using at least one electrical signal of the sensed first plurality of electrical signals and at least one electrical signal of the sensed second plurality of electrical signals, one or more therapy parameter values; and
control the stimulation circuitry to deliver therapy to the brain of the patient according to the determined therapy parameter values.
