K934884 is an FDA 510(k) clearance for the MODEL 2231 CO2 INSUFFLATOR. Classified as Insufflator, Laparoscopic (product code HIF), Class II - Special Controls.

Submitted by Richard Wolf Medical Instruments Corp. (Vernon Hills, US). The FDA issued a Cleared decision on February 7, 1995 after a review of 483 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Obstetrics & Gynecology FDA review panel, regulated under 21 CFR 884.1730 - 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.
