Abstract

A programming device compares filter information to information that describes possible combinations of the electrodes within an electrode set implanted in a patient. The filter information describes at least one characteristic of valid, e.g., desired, electrode combinations, and in exemplary embodiments, is received from a user, e.g., a clinician, via a user interface of the programming device. The filter information can describe a number of electrodes in valid combinations, a fixed polarity for an electrode for valid combinations, or relational characteristics of the electrodes of valid combinations. The comparison process may be iterative. The programming device identifies a subset of the possible electrode combinations based on the comparison. By identifying the valid subset of electrode combinations based on the filter information, the programming device may reduce the amount of clinician and patient time required to program an implantable neurostimulator.
