1. An implantable medical system, comprising:
- an implantable component having an implantable power supply; and
an external wireless charger having a charger power supply, a driver, an inductive coil, a battery recharger, and a routing system connected between the driver, the inductive coil, and the battery recharger,wherein the routing system has a first configuration that passes signals from the driver to the inductive coil in order to transcutaneously transmit power from the charger power supply to the implantable power supply via the inductive coil, and wherein the routing system has a second different configuration that passes power received from an auxiliary charger at the inductive coil to the battery recharger for recharging of the charger power supply.

17. A method for operating a cochlear implant comprising an implantable component having an implantable power supply, an external wireless charger having a charger power supply, a driver, an inductive coil, a battery recharger, and a routing system connected between the driver, the inductive coil, and the battery recharger, the method comprising:
-
providing, via the routing system, power signals from the driver to the inductive coil; transmitting, based on the power signals received via the routing system, power from the charger power supply to the implantable power supply via the inductive coil; disabling, using the routing system, transmission of power from the charger power supply to the implantable power supply; wirelessly receiving, via the inductive coil, power from an auxiliary charger; and providing, via the routing system, the power received from the auxiliary charger to the battery recharger to recharge the charger power supply. - View Dependent Claims (18, 19, 20)
