K953269 is an FDA 510(k) clearance for the SAFECIRCUIT MANIFOLD/PULMONARY UNIT. Classified as Apparatus, Gas-scavenging (product code CBN), Class II - Special Controls.

Submitted by Advanced Warming Systems, Inc. (Lubbock, US). The FDA issued a Cleared decision on December 20, 1996 after a review of 526 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.5430 - 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.
