Abstract:
1. A system for communicating with a medical device implanted within a patient's body, comprising: one or more implants for placement within the body, each implant including an electrical circuit configured to perform one or more commands when the implant is activated, an energy storage device, an acoustic switch coupled between the electrical circuit and the energy storage device, and one or more acoustic implant transducers coupled to the acoustic switch, the one or more acoustic implant transducers configured for receiving an acoustic control signal to activate the acoustic switch between a first state, in which current is limited from flowing from the energy storage device to the electrical circuit, and a second state, in which current flows from the energy storage device to the electrical circuit; an external controller for placement outside of the body, the external controller including one or more acoustic controller transducers for transmitting and receiving acoustic signals, wherein the transmitted acoustic signals include at least the acoustic control signal; and an external monitoring device in communication with the external controller, the external monitoring device configured to monitor one or more physiological parameters within the body.
