K933953 is an FDA 510(k) clearance for the PHOTOTHERAPEUTIX MODEL 1650B. Classified as Light, Ultraviolet, Dermatological (product code FTC), Class II - Special Controls.

Submitted by Avex Industries , Ltd. (Hudson Falls, US). The FDA issued a Cleared decision on February 21, 1995 after a review of 558 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the General & Plastic Surgery FDA review panel, regulated under 21 CFR 878.4630 - the FDA general and plastic surgery 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 General & Plastic Surgery submissions.
