Abstract
A system and method for automatically adjusting the value of a parameter defined to manage and control the resources recruited by an implantable medical device to supply power or the device to deliver an instance of an electrical stimulation therapy to a patient. In embodiments, the parameter corresponds to a number of capacitors the discharge of which supplies the power to deliver a stimulation therapy at a programmed amplitude. Whenever the circumstances prevent the programmed amplitude from being delivered, the system and method automatically adjust the resource-controlling parameter to use the minimum power to achieve the desired (programmed) amplitude or as close as possible to that programmed amplitude. Some embodiments additionally include using another parameter (a equivalent amplitude parameter) to balance the charge delivered through multiple pathways in parallel sourced from a single reservoir of power.
