Submitted by Elmed, Inc. (Addison, US). The FDA issued a Cleared decision on November 5, 1992 after a review of 321 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 878.4400 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the General & Plastic Surgery review framework, consistent with the majority of Class II 510(k) submissions.
