Wireless system for epilepsy monitoring and measurement
First Claim
1. A wireless system for brain monitoring/mapping of neurological-disorder patients, the system comprising:
- a plurality of electrodes each configured for surface abutment of brain tissue;
main circuitry for placement outside a body of a patient and configured to transmit power at radio frequencies and send and receive data using infrared energy; and
remote circuitry for subcutaneous implantation in a head of the patient, the remote circuitry being connected to the plurality of electrodes and including a multiplexer sampling signals from the plurality of electrodes, the multiplexer outputting electrode signals to an amplifier and A/D converter for transmission to the main circuitry, wherein the remote circuitry is configured to (a) receive transmitted power at radio frequencies from the main circuitry, (b) capture and digitize full-bandwidth EEG signals from each of the electrodes, and (c) send data to and receive data from the main circuitry using infrared energy, including sending the digitized full-bandwidth EEG signals from each of the electrodes.

Abstract
A wireless system for brain monitoring/mapping of neurological-disorder patients includes a plurality of electrodes each configured for surface abutment of brain tissue and main circuitry for placement outside a body of a patient and configured to transmit power at radio frequencies and send and receive data using infrared energy. Remote circuitry is provided for subcutaneous implantation in a head of the patient. The remote circuitry is connected to the plurality of electrodes and includes a multiplexer sampling signals from the plurality of electrodes. The multiplexer outputs electrode signals to an amplifier and A/D converter for transmission to the main circuitry. The remote circuitry is configured to (a) receive transmitted power at radio frequencies from the main circuitry, (b) capture and digitize full-bandwidth EEG signals from each of the electrodes, and (c) send data to and receive data from the main circuitry using infrared energy.
