K922497 is an FDA 510(k) clearance for the OPTILASE ND:YAG MODELS 1000/4000 SURG LASER SYSTEM. Classified as Powered Laser Surgical Instrument within the GEX classification (a category for powered laser surgical instruments across multiple specialties), Class II - Special Controls.

Submitted by Trimedyne, Inc. (Irvine, US). The FDA issued a Cleared decision on March 1, 1994 after a review of 643 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 878.4810 - 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.
