Title: Patient activated telemetry control unit using bidirectional asymmetricdual-mode telemetry link to communicate with an implanted device

Abstract: A dual-mode telemetry system that allows digital binary data to beefficiently transferred between an implantable device and a patientcontrol unit. The patient control unit utilizes a bidirectional,asymmetric, telemetry link, wherein in a first mode, the patient controlunit transmits data at a high bit rate to the implanted device, and in asecond mode, the patient control unit receives data at a low bit rate fromthe implanted device. The telemetry system is relatively simple andinexpensive to construct, and requires minimal modifications to theimplanted device.
