Abstract:
1. An implantable medical device, comprising: a tank circuit tuned to a recharge frequency of recharge energy; a receiver with at least one input electrically connected to a node of the tank circuit, the receiver being configured to receive telemetry signals at a telemetry frequency that is different than the recharge frequency while the tank circuit is tuned to the recharge frequency; a controller that is coupled to the tank circuit that tunes the tank circuit to the telemetry frequency and the recharge frequency and that is coupled to the receiver, wherein in response to the controller receiving a recharge instruction obtained from telemetry signals received through the receiver, the controller tunes the tank circuit to the recharge frequency; a rechargeable power source; a rectifier that is electrically connected between the rechargeable power source and the tank circuit and that is configured to receive the recharge energy at the recharge frequency; and medical circuitry electrically connected to the rechargeable power source.
