FDA Approves Mysterious 'Field Generator Positioning Devices' for Brains

## Summary

The FDA has officially classified the field generator positioning device as a low-risk, Class I device, making it easier and faster for patients to get access to this helpful technology. This change reduces red tape for manufacturers without compromising safety or effectiveness. The new classification took effect on November 26, 2025, but has been in place since July 10, 2020, so no new costs or delays are expected.

We are taking this action because we have determined that classifying the device into class I (general controls) will provide a reasonable assurance of 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.
