Identifying combinations of electrodes for neurostimulation therapy
First Claim
1. A method for testing a plurality of combinations of electrodes from a set of electrodes implanted within a patient, wherein testing each of the plurality of electrode combinations comprises delivering neurostimulation therapy from a medical device to a patient via the electrode combination, the method comprising:
- identifying an initial position within the set of electrodes;
selecting different ones of the electrodes of the set as a first electrode in an order based on decreasing proximity of the electrodes to the initial position; and
for each of the selected first electrodes, testing neurostimulation therapy provided by a subset of the plurality of the electrode combinations, wherein each of the electrode combinations of the subset includes the respective first electrode and one or more additional electrodes from the set of electrodes.

Abstract
A programmer allows a clinician to identify combinations of electrodes from within an electrode set implanted in a patient that enable delivery of desirable neurostimulation therapy by an implantable medical device. The programmer executes an electrode combination search algorithm to select combinations of electrodes to test in a non-random order. According to algorithms consistent with the invention, the programmer may first identify a position of a first cathode for subsequent combinations, and then select electrodes from the set to test with the first cathode as anodes or additional cathodes based on the proximity of the electrodes to the first cathode. The programmer may store information for each combination tested, and the information may facilitate the identification of desirable electrode combinations by the clinician. The clinician may create neurostimulation therapy programs that include identified desirable program combinations.
