A method and an apparatus for projecting an end of service (EOS) and/or an elective replacement indication (ERI) of a component in an implantable device and for determining an impedance experienced by a lead associated with the implantable device. An active charge depletion of an implantable device is determined. An inactive charge depletion of the implantable device is determined. A time period until an end of service (EOS) and/or elective replacement indication (ERI) of a power supply associated with the IMD based upon the active charge depletion, the inactive charge depletion, and the initial and final (EOS) battery charges, is determined. Furthermore, to determine the impedance described above, a substantially constant current signal is provided through a first terminal and a second terminal of the lead. A voltage across the first and second terminals is measured. An impedance across the first and second terminals is determined based upon the constant current signal and the measured voltage.

Cette invention concerne un appareil et un procédé permettant de projeter une indication de fin de service (EOS) et/ou une indication de remplacement facultatif (ERI) d'un composant dans un dispositif implantable et de déterminer l'impédance subie par un conducteur associé au dispositif implantable. A cet effet, on détermine l'état d'appauvrissement de charge active du dispositif implantable et on détermine l'état d'appauvrissement de charge inactive du dispositif implantable. On détermine une période courant jusqu'à une indication de fin de service (EOS) et/ou jusqu'à une indication de remplacement facultatif (ERI) d'une source d'alimentation associée au dispositif médical implantable, sur la base de l'appauvrissement de charge active, de l'appauvrissement de charge inactive et des charges initiale et finale de la batterie (EOS). En outre, pour déterminer l'impédance décrite ci-dessus, un signal de courant essentiellement constant est appliqué à une première borne et à une seconde borne du conducteur. On mesure la tension sur ces première et seconde bornes. On détermine l'impédance sur ces première et seconde bornes, sur la base du signal de courant constant et de la tension mesurée.
