### Description

The FDA is classifying the focused ultrasound system for non-thermal, mechanical tissue ablation as a Class II medical device subject to special controls. The device uses focused ultrasound to mechanically ablate soft tissue and is not intended to thermally ablate tissue. The order codifies the classification and identifies requirements including clinical, animal, and non-clinical performance testing, electrical safety and electromagnetic compatibility, biocompatibility, software and human-factors testing, and labeling. FDA states that the classification provides reasonable assurance of safety and effectiveness and is intended in part to reduce regulatory burdens and enhance patient access to innovative devices.
