What is it indicated for?
ENOBIO is an EEG portable monitoring device of 8, 20, 32 channels intended for the use in clinical patient monitoring
for use in hospitals and other medical environments.
The Enobio is intended to acquire, store, transmit and display electrophysiological signals in wireless mode as an aid in
diagnostics. The system digitizes analogue EEG signals collected by a cap with electrodes, amplifies them, and uses WiFi
connectivity to transmit the EEG data to a dedicated host computer with the software.
This device is intended to be used by trained health-care personnel. It is restricted to sale by or on order of a physician.
Indications for use as stated in the FDA summary.
