Submitted by Protologic, Inc. (Webster, US). The FDA issued a Cleared decision on January 22, 1990 after a review of 172 days - an extended review cycle.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.5270 - 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: Standard predicate-based submission. Standard predicate reliance. Neonatal respiratory circuit components typically face extended FDA review due to heightened safety scrutiny for pediatric patient populations - the 176-day cycle reflects this additional regulatory diligence.
