Abstract

An implantable medical device (IMD) delivers neurostimulation therapy to a patient according to a parameter set, which may consist of a number of programs that are delivered substantially simultaneously. When programming the IMD, a clinician programmer may maintain a session log for the patient that includes a listing of programs delivered to the patient and rating information provided by a clinician and the patient for programs of the list. The listing may be ordered according to the rating information in order to facilitate the selection of programs for a parameter set. A program library that may include particularly effective programs organized according to a directory structure may be stored in a memory. The IMD and/or a patient programmer may store usage information that provides an objective assessment of therapy use by the patient, and allows a clinician to later improve the therapy based on the usage information.
