External device for determining an optimal implantable medical device for a patient using information determined during an external trial stimulation phase

摘要

An external controller is disclosed for communicating with an external trial stimulator (ETS) for an implantable medical device. The external controller is programmed with a battery algorithm able to assist a clinician in choosing a suitable implant for the patient based on battery performance parameters estimated for a number of implants during an external trial stimulation phase that precedes implantation of the implant. The algorithm is particularly useful in assisting the clinician in choosing between a rechargeable-battery implant or a primary-battery implant for the patient.
