Device Classification

Product Code OLZ Automatic Event Detection Software For Polysomnograph With Electroencephalograph
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 882.1400
Definition Automatically Mark Electroencephalograph And Polysomongraph Signals In Order To Aid In Identification Of Such Events And Annotation Of Prolonged Psg Traces; Automatically Calculate Simple Measures Obtained From Recorded Signals (e.g. Magnitude, Time, Frequency And Simple Statistical Measures Of Marked Events); All Output Subject To Verification By Qualified User
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Neurology devices follow this clearance model.
