K093584 is an FDA 510(k) clearance for the EZ-MISTER. Classified as Applicator (laryngo-tracheal), Topical Anesthesia (product code CCT), Class II - Special Controls.

Submitted by N.M. Beale Co., Inc. (Ayer, US). The FDA issued a Cleared decision on March 4, 2011 after a review of 470 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.5170 - 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.

What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Anesthesiology devices follow this clearance model.
