摘要： Implantable devices and related systems utilize power management features in conjunction with a recharge circuit that includes a coil and capacitance. The reactance such as the capacitance and/or inductance may be variable such that in the event of an overcharge condition, the reactance may be varied to change the resonant frequency of the circuit of the coil from the recharge frequency to another frequency to reduce the power being received. Other power management features may additionally or alternatively be employed. For instance, the device may send an uplink telemetry signal to an external device to request that recharge power be decreased. The device may switch additional resistance into the circuit of the coil to reduce the Q of the circuit. As another example, the device may clamp the circuit of the coil to ground.

摘要： Implantable devices and related systems utilize a single coil for both inductive telemetry at one telemetry signal frequency and recharge at another recharge energy frequency. The coil is included in a tank circuit that may have a variable reactance. During telemetry, particularly outside of a recharge period, the reactance may be set so that the tank circuit is tuned to the telemetry frequency. During recharge, the reactance is set so that the tank circuit is tuned to the recharge frequency. Furthermore, the tank circuit may have a Q that is sufficiently small that the tank circuit receives telemetry frequency signals that can be decoded by a receiver while the tank is tuned to the recharge frequency so that telemetry for recharge status purposes may be done during the recharge period without changing the tuning of the tank circuit.

摘要： Aspects of this disclosure relate to coupling and decoupling a power source of a device with circuitry within the device. For example, in aspects of this disclosure, when a short develops within the device, a switch circuit may decouple the power source from the some of the circuitry within the device. Decoupling the power source when a short develops may extent the operational time of the power source, and may reduce thermal excursion.

摘要： A charging system is disclosed. In one embodiment, the system includes a charging unit having a primary coil, and an implantable medical device comprising a secondary coil to receive charge from the primary coil. The implantable medical device further includes a half-wave voltage-doubling rectifier coupled to the secondary coil, a full-wave rectifier coupled to the secondary coil, and a rechargeable power source. Control logic is provided to periodically configure the rechargeable power source to receive charge from a selected one of the voltage-doubling circuit and the full-wave rectifier in a manner that increases rate at which charge is transferred from the secondary coil to the rechargeable power source. The control logic may configure the rechargeable power source to receive charge based on one or more monitored conditions which may include, for example, an indication of a current, a voltage, a coupling coefficient, back-scatter, and temperature.
