Patent ID: 8326418

Claim:
A medical system comprising: a plurality of electrodes; at least one sensor configured to output at least one signal based on at least one physiological parameter of a patient; and a processor configured to: control delivery of stimulation to the patient using a plurality of electrode configurations, wherein each of the electrode configurations comprises at least one of the plurality of electrodes, for each of the electrode configurations, determine a first response of target tissue to the stimulation based on the signals, and a second response of non-target tissue to the stimulation based on the signals, select at least one of the electrode configurations for delivery of stimulation to the patient based on the first and second responses for the electrode configurations; and store the selected electrode configurations for delivery of stimulation to the patient in a memory; and wherein the first response of target tissue comprises a first capture threshold of target tissue and the second response of non-target tissue comprises a second capture threshold of non-target tissue and wherein selecting at least one of the electrode configurations for delivery of stimulation to the patient based on the first and second responses for the electrode configurations includes determining a value of a suitability index for each of the electrode configurations based on a ratio of the first capture threshold to the second capture threshold for each of the electrode configurations.
