New device zaps nerves to tame high blood pressure
NCT ID NCT07061054
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tests a device called the Netrod renal denervation system in 20 adults with uncontrolled high blood pressure who are not taking blood pressure pills. The device uses radiofrequency energy to calm overactive kidney nerves, which may help lower blood pressure. Researchers will check safety and blood pressure changes over three months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Netrod™ renal denervation system (catheter and generator)
- What this could lead to
- If successful, this could offer a drug-free option to control high blood pressure, reducing the need for daily medication.
- What could go wrong
- This is a very small pilot study with only 20 people, so results may not apply broadly. The procedure carries risks like blood vessel damage or kidney problems.
