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.
