K925478 is an FDA 510(k) clearance for the ELECTROSURGICAL ELECTRODE. Classified as Electrocautery, Gynecologic (and Accessories) (product code HGI), Class II - Special Controls.

Submitted by Megadyne Medical Products, Inc. (Murray, US). The FDA issued a Cleared decision on June 27, 1994 after a review of 606 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Obstetrics & Gynecology FDA review panel, regulated under 21 CFR 884.4120 - the FDA obstetrics and gynecology 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 Obstetrics & Gynecology submissions.
