K901329 is an FDA 510(k) clearance for the CEPHALIC DOPPLER W/ULTRAMARK 9 ULTRASOUND SYSTEM. Classified as System, Imaging, Pulsed Doppler, Ultrasonic within the IYN classification (a category covering pulsed Doppler and ultrasound imaging systems), Class II - Special Controls.

Submitted by Advanced Technology Laboratories, Inc. (Bothell, US). The FDA issued a Cleared decision on November 23, 1990 after a review of 247 days - an extended review cycle.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.1550 - 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: Standard predicate-based submission. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Radiology review framework, consistent with the majority of Class II 510(k) submissions.
