K193351 is an FDA 510(k) clearance for the NinesAI. Classified as Radiological Computer-assisted Triage And Notification Software (product code QAS), Class II - Special Controls.

Submitted by Nines, Inc. (Palo Alto, US). The FDA issued a Cleared decision on April 21, 2020 after a review of 140 days - within the typical 510(k) review window.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.2080 - 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: Incremental AI imaging tool. Moderate equivalence dependency. Overall, this clearance reflects a predicate-aligned approval typical of modern AI radiology extensions - not a novel clinical breakthrough, but a validated iteration within an established regulatory category.

Device Classification

Product Code QAS Radiological Computer-assisted Triage And Notification Software
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 892.2080
Definition Radiological Computer-assisted Triage And Notification Software Is An Image Processing Device Intended To Aid In Prioritization And Triage Of Time Sensitive Patient Detection And Diagnosis Based On The Analysis Of Medical Images Acquired From Radiological Signal Acquisition Systems. The Device Identifies Or Prioritizes Time Sensitive Imaging For Review By Prespecified Clinical Users Based On Software-based Image Analysis But Does Not Provide Information From The Image Analysis Other Than Triage And Notification .
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Radiology devices follow this clearance model.
