K922420 is an FDA 510(k) clearance for the CONTINUOUS FLOW HYSTERO-RESECTOSCOPE. Classified as Hysteroscope (and Accessories) (product code HIH), Class II - Special Controls.

Submitted by Linvatec Corp. (Largo, US). The FDA issued a Cleared decision on June 14, 1994 after a review of 754 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Obstetrics & Gynecology FDA review panel, regulated under 21 CFR 884.1690 - 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.
