K921220 is an FDA 510(k) clearance for the BREATHE RIGHT. Classified as Dilator, Nasal (product code LWF), Class I - General Controls.
Submitted by Cns, Inc. (Chanhassen, US). The FDA issued a Cleared decision on October 7, 1993 after a review of 573 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 874.3900 - 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.
