Submitted by Norco, Inc. (Boise, US). The FDA issued a Cleared decision on June 18, 1991 after a review of 76 days - a notably fast clearance cycle.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.6400 - the FDA anesthesiology and respiratory 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.
