K801604 is an FDA 510(k) clearance for the PATHFINDER ELECTRODIAGNOSTIC SYSTEM. Classified as Conditioner, Signal, Physiological (product code GWK), Class II - Special Controls.

Submitted by Nicolet Biomedical Instruments (Mchenry, US). The FDA issued a Cleared decision on August 4, 1980 after a review of 21 days - a notably fast clearance cycle.

This device falls under the Neurology FDA review panel, regulated under 21 CFR 882.1845 - 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: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
