Abstract

Controller, system and method for an implantable medical device having a plurality of electrodes, said implantable device being capable of delivering a therapeutic stimulation to a patient. An electrode interface is operatively coupled between a plurality of electrodes and a control module. The control module uses an 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. A user interface displays an indicia, indicative of operability of a group of at least one of said plurality of electrodes, based on a comparison of said plurality of measurements to a predetermined range, said indicia being a qualitative representation of operability of said group of at least one of said plurality of electrodes.

Claims

1. A controller for an implantable medical device having a plurality of electrodes, said implantable device being capable of delivering a therapeutic stimulation to a patient, comprising:

a control module;

a user interface providing control of said control module by a medical professional;

an electrode interface operatively coupled between said plurality of electrodes and said control module;

wherein said control module uses said electrode interface to obtain a plurality of measurements of impedance values for a plurality of selected pairs of individual ones of said plurality of electrodes; and

wherein said user interface displays an indicia, indicative of operability of a group of at least one of said plurality of electrodes, based on a comparison of said plurality of measurements to a predetermined range, said indicia being a qualitative representation of operability of said group of at least one of said plurality of electrodes.
