K152224 is an FDA 510(k) clearance for the Proton Therapy System - Proteus 235 (Proteus One, Proteus Plus, Proteus TK2). Classified as System, Radiation Therapy, Charged-particle, Medical (product code LHN), Class II - Special Controls.

Submitted by Ion Beam Application S.A. (Louvain-La-Neuve, BE). The FDA issued a Cleared decision on August 9, 2016 after a review of 368 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.5050 - 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.
