K931322 is an FDA 510(k) clearance for the KS 5 - CLINICAL AUDIOMETER. Classified as Audiometer (product code EWO), Class II - Special Controls.

Submitted by Maico Hearing Instruments, Inc. (Minneapolis, US). The FDA issued a Cleared decision on August 19, 1994 after a review of 521 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Ear, Nose, Throat FDA review panel, regulated under 21 CFR 874.1050 - the FDA ear, nose and throat 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 Ear, Nose, Throat submissions.
