Title
(EN) EMULATING PASSIVE DISCHARGE OF ELECTRODES USING A PROGRAMMABLE EXPONENTIALLY-DECREASING AMPLITUDE DISCHARGE CURRENT
(FR) ÉMULATION DE DÉCHARGE PASSIVE D'ÉLECTRODES À L'AIDE D'UN COURANT DE DÉCHARGE À AMPLITUDE À DÉCROISSANCE EXPONENTIELLE PROGRAMMABLE
Abstract
(EN)
Embodiments are directed to an implantable medical device comprising stimulation circuitry for controlling delivery of a medical therapy to a patient, a processor for controlling the IMD according to executable code, and a power source. The implantable medical device may further include current regulator circuitry comprising electrode selection circuitry that is configured to select electrodes for use during a discharge mode, and a programmable current regulator configured to provide an exponentially decreasing discharge current to the selected electrodes from the power source. A current output of a programmable current regulator may be decreased in precalculated steps to create the exponentially decreasing discharge current applied to the selected electrodes.

Conformément à des modes de réalisation, la présente invention concerne un dispositif médical implantable comprenant une circuiterie de stimulation pour commander l'administration d'une thérapie médicale à un patient, un processeur pour commander le dispositif médical implantable (IMD) selon un code exécutable, et une source d'alimentation. Le dispositif médical implantable peut en outre comprendre une circuiterie de régulateur de courant comprenant une circuiterie de sélection d'électrode qui est configurée pour sélectionner des électrodes destinées à être utilisées pendant un mode de décharge, et un régulateur de courant programmable configuré pour fournir un courant de décharge à décroissance exponentielle aux électrodes sélectionnées à partir de la source d'alimentation. Un courant de sortie d'un régulateur de courant programmable peut être réduit dans des étapes pré-calculées pour créer le courant de décharge à décroissance exponentielle appliqué aux électrodes sélectionnées.
