K915550 is an FDA 510(k) clearance for the MINI DOPPLER II ULTRASOUND BLOOD FLOW DETECTOR. Classified as Flowmeter, Blood, Cardiovascular (product code DPW), Class II - Special Controls.

Submitted by Koven and Assoc., Inc. (St. Louis, US). The FDA issued a Cleared decision on December 10, 1992 after a review of 365 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 870.2100 - 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.
