K881263 is an FDA 510(k) clearance for the MODEL 500A VASCULAR SPECTRUM ANALYZER W/DOPPLER. Classified as Transducer, Ultrasonic, Obstetric (product code HGL), Class II - Special Controls.

Submitted by Multigon Industries, Inc. (Mt. Vernon, US). The FDA issued a Cleared decision on January 5, 1990 after a review of 652 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Obstetrics & Gynecology FDA review panel, regulated under 21 CFR 884.2960 - 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.
