Title: Detection of possible failure of capacitive elements in an implantable medical device

Abstract: Apparatus and method for monitoring capacitive elements of an implantable medical device system for device failure and responding thereto. A therapy measurement block monitors a charge value across one or more capacitive elements. If the charge value falls outside a prescribed range, indicating possible failure in the capacitive element, the system removes from service the capacitive element and its associated regulator, notifies the implantable neuro stimulator of the failure and/or takes appropriate corrective measures.
