Relay module for implant

A system comprising:

• a wireless medical device configured to be implanted inside a patient and to be remotely powered by energy in electromagnetic signals via electrical radiative coupling such that the wireless medical device does not require electrical power from any other source to operate;
• a relay device configured to direct electromagnetic signals to the wireless medical device;
• and
• a control device configured to:
• generate a first electromagnetic signal for the wireless medical device;
• and
• direct the first electromagnetic signal to the relay device, wherein the wireless medical device is powered based on the first electromagnetic signal.

A method for facilitating neurophysiological treatment of a patient, the method comprising:

• generating, at a control device outside of a patient, an electromagnetic signal;
• transmitting, from the control device, the electromagnetic signal to a relay device;
• obtaining, at a wireless medical device implanted in the patient, energy via electrical radiative coupling based on the electromagnetic signal, the wireless medical device being powered by the energy such that the wireless medical device does not require electrical power from any other source to operate;
• generating, by the wireless medical device, a stimulation waveform using the energy;
• and
• applying, by the wireless medical device, the stimulation waveform to excitable tissue of the patient.
