K840398 is an FDA 510(k) clearance for the INLINE FOAM NOSE. Classified as Condenser, Heat And Moisture (artificial Nose) (product code BYD), Class I - General Controls.

Submitted by Mallinckrodt Critical Care (Walker, US). The FDA issued a Cleared decision on March 16, 1984 after a review of 46 days - a notably fast clearance cycle.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.5375 - 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.
