K933445 is an FDA 510(k) clearance for the DPS 100 MULTIPORT ILLUMINATION SYSTEM (MIS). Classified as Transilluminator, Ac-powered (product code HJM), Class II - Special Controls.

Submitted by Storz Instrument Co. (St. Louis, US). The FDA issued a Cleared decision on September 23, 1994 after a review of 437 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Ophthalmic FDA review panel, regulated under 21 CFR 886.1945 - the FDA ophthalmic 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 Ophthalmic submissions.
