NeuroSense Cortical EEG Analyzer Gets EU Green Light

MedCity News is reporting thatNeuroWave Systems of Cleveland Heights, Ohio has received the European CE Mark for its NeuroSENSE Monitor. The device implements an EEG system that measures signals separately in the left and right parts of the brain, giving anesthesiologists and emergency physicians guidance on ongoing events, such as the level of consciousness in OR or a stroke in the emergency room. The company clearly hopes to become the next generation neuromonitoring technology for anesthesiologists looking for ways to monitor the depth of anesthesia. Check out the following graph that shows a comparison example of the WAVCNS and BIS (v.3.4.) time courses in an arthroscopy case.
Some details from the product brochure:

The NeuroSENSE Model NS-701 is a peri-operative bilateral brain function monitor. The system acquires and displays 2 frontal EEG signals, and calculates a number of processed EEG parameters including the WAVCNS, a wavelet-based quantifier of cortical activity. Providing continuous and delay-free tracking of the patient’s brain state, the NeuroSENSE is an easy-to-use and robust aid for monitoring brain activity levels in patients in the OR, ICU, ER and other clinical settings.

Processed Variables for each brain hemisphere:
  • WAVCNS cortical quantifier
  • Electromyographic power (70-110 Hz)
