FDA Classifies Brain Temperature Measurement Systems as Class II Devices
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
This rule places brain temperature measurement systems in FDA class II, which means manufacturers must meet special controls instead of going through the toughest approval path. The devices are prescription-only and still need premarket notification under 510(k), so companies planning to sell them in the U.S. must build in testing, software validation, biocompatibility, usability, safety checks, and detailed labeling that warns about limits and risks. For device makers, the practical effect is lower regulatory burden than class III, but not a free pass. The rule also sets the baseline requirements future similar devices can use as a predicate, which may make follow-on products easier to clear.

Key Changes
- Brain temperature measurement systems are now classified as FDA class II devices with special controls.
- Manufacturers must meet specific testing, software, biocompatibility, usability, and labeling requirements.
- The devices remain prescription-only and are still subject to 510(k) premarket notification.
Obligations
What this law requires
Manufacturers of brain temperature measurement systems must ensure the device complies with the FDA special controls for class II classification to avoid automatic class III treatment.
Manufacturers must conduct in vivo performance testing to show the device performs as intended under anticipated conditions of use and accurately and reliably measures brain temperature against a ground truth measurement.
Manufacturers must perform non-clinical performance testing to demonstrate accurate measurement of brain temperature changes under simulated use conditions, including repeatability within pre-specified clinically relevant parameters and full characterization of hardware and software technical specifications.
Manufacturers must perform electrical safety, thermal safety, mechanical safety, and electromagnetic compatibility testing.
Manufacturers must provide software documentation with a detailed technical description of the algorithm(s) used to generate device output and must support the software with verification and validation testing based on software requirements and hazard analysis.
