K984203 is an FDA 510(k) clearance for the SIUI APOGEE 800PLUS ULTRASOUND IMAGING 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 Shantou Institute of Ultrasonic Instuments (Walnut Creek, US). The FDA issued a Cleared decision on November 1, 1999 after a review of 342 days - an unusually long review period, suggesting complex equivalence evaluation.

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. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Radiology review framework, consistent with the majority of Class II 510(k) submissions.
