K033543 is an FDA 510(k) clearance for the NARCOTREND, MODEL COMPACT 4.0. Classified as Index-generating Electroencephalograph Software (product code OLW), Class II - Special Controls.

Submitted by Mt Monitortechnik GmbH & Co. KG (Bad Bramstedt, DE). The FDA issued a Cleared decision on September 17, 2004 after a review of 312 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.
