Zusammenfassung:External power source (48), and system and method using such external power source (48), for an implantable medical device (16) having therapeutic componentry (28) and a secondary coil (34) operatively coupled to the therapeutic componentry (28). A primary coil (54) is capable of inductively energizing the secondary coil (34) when externally placed in proximity of the secondary coil (34). A repositionable magnetic core (58) associated with the primary coil (54) is capable of being repositioned by a user of the external power source (48). An indicator is capable of providing the user with information relative to coupling between the primary coil (54) and the secondary coil (34) as a function of repositioning of the repositionable magnetic core (58). La présente invention concerne une source externe d'énergie (48) pour un dispositif médical implantable (16) dont l'équipement thérapeutique (28) est fonctionnellement couplé à un enroulement secondaire (24). L'invention concerne également un système et un procédé permettant l'utilisation d'une telle source externe d'énergie (48). En l'occurrence, un enroulement primaire (54) fournit par induction à l'enroulement secondaire (34) de l'énergie lorsqu'il en est extérieurement proche. L'utilisateur de la source externe d'énergie (48) dispose à cet effet d'un noyau magnétique (58) mobile, associé à l'enroulement primaire (54). Un témoin renseigne l'utilisateur sur le couplage entre l'enroulement primaire (54) et l'enroulement secondaire (34) selon le déplacement du noyau magnétique (58).
