K904290 is an FDA 510(k) clearance for the NOZOVENT, NASAL DILATOR. Classified as Dilator, Nasal (product code LWF), Class I - General Controls.

Submitted by Wpm Intl AB Intl Trade & Managemet Consulting (Sweden, SE). The FDA issued a Cleared decision on August 20, 1991 after a review of 337 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Ear, Nose, Throat review framework, consistent with the majority of Class II 510(k) submissions.
