K953983 is an FDA 510(k) clearance for the EVAP-ELECTRODES TYPES 8423, 8427, 8410 & 8413 ELECTROSURGICAL VAPORIZATION OF.... Classified as Electrode, Electrosurgical, Active, Urological (product code FAS), Class II - Special Controls.

Submitted by Richard Wolf Medical Instruments Corp. (Vernon Hills, US). The FDA issued a Cleared decision on October 2, 1996 after a review of 406 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Gastroenterology & Urology FDA review panel, regulated under 21 CFR 876.4300 - 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.
