FDA Classifies Brain Temp Monitors for Easier Access
Published Date: 4/30/2026
Rule
Summary
The FDA is officially putting brain temperature measurement systems into Class II, meaning they’ll follow special safety rules but face fewer hurdles than before. This change helps make sure these devices are safe and effective while speeding up patient access to cool new tech. The new classification is effective April 30, 2026, and could save companies time and money by reducing red tape.

Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
Class II status speeds patient access
You may get access to brain temperature measurement devices more quickly because the FDA classified the device type as Class II (special controls). The FDA said this classification will enhance patients' access to beneficial innovation and is effective April 30, 2026 (classification was applicable March 29, 2022).
Lower regulatory burden for device makers
If you make brain temperature measurement systems, the device being placed in Class II (special controls) instead of automatically remaining in Class III can reduce regulatory burdens and could save companies time and money. The FDA says Class II classification via the De Novo process lets this device serve as a predicate for future devices, which can allow other sponsors to use the 510(k) pathway.
510(k) premarket notification still required
If you plan to market a brain temperature measurement system, the device is subject to premarket notification under section 510(k) of the FD&C Act; FDA has not exempted this device type under section 510(m). This requirement remains in force as codified in 21 CFR 882.1565.
Required safety tests and labeling for devices
Brain temperature measurement systems must meet specific special controls, including in vivo and non-clinical performance testing, electrical/thermal/mechanical and electromagnetic safety testing, software verification and validation, biocompatibility, usability evaluation, and detailed labeling with warnings (for example: that the device is not intended to measure core body temperature). These controls are codified at 21 CFR 882.1565.
