K925735 is an FDA 510(k) clearance for the EEG ANALYZER. Classified as Analyzer, Spectrum, Electroencephalogram Signal (product code GWS), Class I - General Controls.

Submitted by Bio-Scan, Inc. (Lancaster, US). The FDA issued a Cleared decision on December 3, 1993 after a review of 385 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Neurology FDA review panel, regulated under 21 CFR 882.1420 - 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.
