K965223 is an FDA 510(k) clearance for the RESOLVE OPTION FOR THE ORACLE IN VISION INTRAVASCULAR ULTRASONIC IMAGING SYSTEM. Classified as System, Imaging, Pulsed Echo, Ultrasonic (product code IYO), Class II - Special Controls.

Submitted by Endosonics Corp. (Rancho Cordova,, US). The FDA issued a Cleared decision on June 29, 1998 after a review of 545 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.1560 - the FDA radiology and imaging software oversight 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 Radiology submissions.
