Medical Devices; General and Plastic Surgery Devices; Classification of the Focused Ultrasound System for Non-Thermal, Mechanical Tissue Ablation
Key claim: FDA is placing focused ultrasound systems that destroy tissue mechanically without heat into a moderate-risk (class II) category with special controls, making it easier to bring those devices to market than under the stricter premarket approval path.
Abstract
(Rule · Health and Human Services Department, Food and Drug Administration) The Food and Drug Administration (FDA) is classifying the focused ultrasound system for non-thermal, mechanical tissue ablation into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for classification of the focused ultrasound system for non-thermal, mechanical tissue ablation. We are taking this action because we have determined that classifying the device into class II will provide a reasonable assurance of the safety and effectiveness of the device. We believe this action will also enhance patients’ access to beneficial innovative devices, in part by reducing regulatory burdens.
Why this matters
Class II classification with special controls lets manufacturers of mechanical (non-thermal) focused ultrasound ablation devices use the 510(k) pathway instead of the more burdensome premarket approval process, which typically speeds and lowers the cost of bringing new models to U.S. patients. The practical effect is incremental: an additional device type now has a defined regulatory lane, consistent with FDA’s broader pattern of down-classifying established device categories.
