K952267 is an FDA 510(k) clearance for the CRITERION, CRITERION I.V., MODIFIED. Classified as Heater, Breathing System W/wo Controller (not Humidifier Or Nebulizer within the BZE classification (a category for neonatal and pediatric respiratory circuit components), Class II - Special Controls.

Submitted by Nova-Ventrx (Northbrook, US). The FDA issued a Cleared decision on December 2, 1997 after a review of 932 days - an unusually long review period, suggesting complex equivalence evaluation.

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: High-complexity regulatory submission. Elevated predicate reliance profile. 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.
