Abstract
An improved integrated external controller/charger system useable with an implantable medical device is disclosed. The system comprises two main components: an external controller and an external charging coil assembly that is coupleable thereto. When the external charging coil assembly is coupled to the external controller, the system can be used to both send and receive data telemetry to and from the implantable medical device, and to send power to the device. Specifically, the external controller controls data telemetry by energizing at least one coil within the external controller, and the external controller controls power transmission by energizing a charging coil in the external charging coil assembly, which is otherwise devoid of its own control, power, and user interface. The result is a cheaper, simpler, more compact, and more convenient data telemetry and charging solution for the patient having a medical implant.
