K160109 is an FDA 510(k) clearance for the Thayer Medical LiteAire Dual-valved, Collapsible MDI Holding Chamber. Classified as Holding Chambers, Direct Patient Interface (product code NVP), Class II - Special Controls.

Submitted by Thayer Medical Corporation (Tucson, US). The FDA issued a Cleared decision on May 19, 2017 after a review of 486 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.5630 - 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.
