Submitted by Mill-Rose Laboratory (Mentor, US). The FDA issued a Cleared decision on February 8, 1993 after a review of 300 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Gastroenterology & Urology FDA review panel, regulated under 21 CFR 876.1500 - the FDA gastroenterology and urology 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. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Gastroenterology & Urology review framework, consistent with the majority of Class II 510(k) submissions.
