The patient control unit utilizes a bidirectional, asymmetric, telemetry link, wherein in a first mode, the patient control unit transmits data at a high bit rate to the implanted device, and in a second mode, the patient control unit receives data at a low bit rate from the implanted device. The telemetry system is relatively simple and inexpensive to construct, and requires minimal modifications to the implanted device. | |
