K920689 is an FDA 510(k) clearance for the DEEMED MSS -- MICROSCOPE SUPPORT SYSTEM. Classified as Microscope, Surgical, General & Plastic Surgery (product code FSO), Class I - General Controls.

Submitted by Deemed, Inc. (Washington, US). The FDA issued a Cleared decision on November 12, 1993 after a review of 637 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 878.4700 - 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.
