K943106 is an FDA 510(k) clearance for the ADULT VENTILATOR. Classified as Ventilator, Continuous, Facility Use (product code CBK), Class II - Special Controls.

Submitted by Infrasonics Corp. (San Diego, US). The FDA issued a Cleared decision on December 28, 1995 after a review of 547 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.5895 - 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.
