K900557 is an FDA 510(k) clearance for the MODIFIED AEROCHAMBER M.V. AEROSOL HOLDING CHAMBER. Classified as Nebulizer, Medicinal, Non-ventilatory (atomizer) (product code CCQ), Class I - General Controls.

Submitted by Monaghan Medical Corp. (Plattsburgh, US). The FDA issued a Cleared decision on April 10, 1991 after a review of 427 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.5640 - 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: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Anesthesiology submissions.
