K232779 is an FDA 510(k) clearance for the QUEX ED. Classified as Reduced- Montage Standard Electroencephalograph (product code OMC), Class II - Special Controls.

Submitted by Qx World, Ltd. (Budapest, HU). The FDA issued a Cleared decision on October 11, 2024 after a review of 396 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Neurology FDA review panel, regulated under 21 CFR 882.1400 - the FDA neurology device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Neurology review framework, consistent with the majority of Class II 510(k) submissions.

Device Classification

Product Code OMC Reduced- Montage Standard Electroencephalograph
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 882.1400
Definition Acquire, Display, Store, And Archive Electroencephalographic Signals From The Brain Using A User-specified And/or Sponsor-specified Locations With A Reduced Array (i.e. Less Than < 16) Of Electrodes
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.
