K181859 is an FDA 510(k) clearance for the Visualase Thermal Therapy System. Classified as System, Image Processing, Radiological within the LLZ classification (a category encompassing advanced image processing and PACS-adjacent software), Class II - Special Controls.

Submitted by Medtronic Navigation, Inc. (Louisville, US). The FDA issued a Cleared decision on March 6, 2019 after a review of 237 days - an extended review cycle.

This device falls under the Neurology FDA review panel, regulated under 21 CFR 892.2050 - the FDA neurology device framework. As a Special 510(k), this submission covers a manufacturer modification to an existing cleared device rather than a new device introduction.

Device pattern: Incremental AI imaging tool. Moderate-to-high 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.
