K921546 is an FDA 510(k) clearance for the VASOVASOSTOMY SET. Classified as Surgical Instruments, G-u, Manual (and Accessories) (product code KOA), Class I - General Controls.

Submitted by Cook Urological, Inc. (Spencer, US). The FDA issued a Cleared decision on July 2, 1993 after a review of 457 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Gastroenterology & Urology FDA review panel, regulated under 21 CFR 876.4730 - 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: 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 Gastroenterology & Urology submissions.
