24/7 EEG™ SubQ


Updated: 03/11/2022

Device Description

UNEEG 24/EEG SubQ is a unique solution to obtain off-line ultra long-term EEG data in the home setting. The device comprises an implantable electrode with two channels and a small external device for power supply and data storage. This ensures robustness of EEG data, high quality of signals and freedom to do everyday activities for the patients. The system comes with software for analysing and visualizing EEG data. It gives an easy overview of seizure activity identified by EEG patterns.
