K160357 is an FDA 510(k) clearance for the TRINITY. 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 Koelis (La Tronche, FR). The FDA issued a Cleared decision on May 2, 2016 after a review of 84 days - a notably fast clearance 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: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
