Abstract

Method, controller and system for an implantable medical device having a plurality of electrodes, the implantable medical device capable of delivering therapeutic stimulation to a patient, comprising a control module, a user interface operatively coupled to the control module, the user interface providing control of the control module by a medical professional or other user, and an electrode interface operatively coupled between the plurality of electrodes and the control module. The control module uses the electrode interface to obtain a plurality of measurements of impedance values for a plurality of selected pairs of individual ones of the plurality of electrodes. The control module determines a prescriptive analysis using the plurality of measurements of impedance values of the selected pairs of individual ones of the plurality of electrodes comparative to a range, and the user interface displays the prescriptive analysis.

Claims
