Summary of Approach:

This 510(k) submission demonstrates substantial equivalence primarily by:

• Listing the device's technical characteristics and comparing them directly to previously cleared predicate devices (Terason uSmart3200T (K131209), Terason™ t3000 (K112953), Terason™ T3200 (K110020)).
• Highlighting that the modifications (addition of three transducers and software updates) do not alter the fundamental technological characteristics or intended use.
• Providing evidence of compliance with a comprehensive set of non-clinical safety, electrical, usability, and acoustic output standards.

The "study" that proves the device meets the "acceptance criteria" here consists of these non-clinical tests and direct comparisons to predicate devices, rather than clinical performance studies with patient data. The regulatory body (FDA) reviews these submissions to ensure the new device is as safe and effective as existing legally marketed devices, without requiring new clinical efficacy data if substantial equivalence is adequately demonstrated.
