Abstract:
An electrically active medical implant, comprising:a circuit, at least one first battery to supply low current to the circuit, a second battery to supply high current to the circuit, a control device to disconnect said at least one first battery from the circuit, and to connect the second battery to the circuit, and a capacitor connected in parallel with said at least one first battery, such that the capacitor can be charged by said at least one first battery during a first circuit status, during which said at least one first battery is connected to the circuit, and during a second circuit status, during which the circuit is connected only to the second battery, wherein the control device again disconnects the second battery from the circuit at an end of the second circuit status, and connects said at least one first battery in parallel to the capacitor and to the circuit for further energy supply.
