Heart monitor repurposed to listen to the brain
NCT ID NCT07752251
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This study tests whether a small, FDA-approved heart monitor (the Medtronic LINQII) can also pick up brain signals when placed temporarily under the scalp. Ten adults undergoing brain surgery for standard care will have two devices implanted during their operation to record about 30 minutes of brain activity. The goal is simply to see if this approach works as a way to capture brain signals, not to treat any condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Medtronic LINQII device (implantable cardiac monitor) placed under the scalp to record brain signals
- What this could lead to
- If successful, this could pave the way for a less invasive way to monitor brain activity over days or weeks, potentially aiding epilepsy or brain disorder management.
- What could go wrong
- This is a small, early feasibility study with only 10 participants. The device is not designed for brain recording, so signal quality may be poor, and there are risks of infection or bleeding from the implant.
