There is provided an implantable system and method for delivering stimulus pulses and/or collecting data from a plurality of sites within a patient's body, having a main controller device with a power source, a stimulator/sensing devices at each of said sites, and circuitry for high frequency transmission of power from the main unit to each of the remote devices. Power is transferred by converting it into a high frequency at the controller unit, and periodically or on request transmitting it to the respective devices. The main controller unit and each respective device also preferably has one or more sensors for collecting data and processor circuitry for analyzing such data. Each remote device has a transmitter for transmitting collected data back to the main controller; the main controller has encoding circuitry for encoding a data component onto the high frequency carrier along with the power component. The controller unit and the respective devices are also equipped with circuitry for controlling power transmission on a need basis, i.e., when the remote device needs power and requests it. The system also performs a transmission parameter test, and adjusts parameters of the transmitted signal, such as frequency and amplitude, as may be indicated.
