Abstract:
1. A method of optimizing the power used by an implantable medical device when delivering electrical stimulation to a human patient, comprising: detecting a first insufficient charge condition when an amplitude of the stimulation the implantable medical device is programmed to deliver cannot in fact be delivered; determining whether a parameter associated with the control of a power source available to deliver an instance of a stimulation can be adjusted to improve the charge condition; if the power-control parameter can be adjusted, then adjusting the power-control parameter in a first direction until an insufficient charge is not encountered; if the power-control parameter cannot be adjusted, then determining whether a working setting of the amplitude exceeds a programmed minimum setting of the amplitude; and if the working setting exceeds the minimum setting, then adjusting the working setting in a first direction until an insufficient charge is not encountered.
