New Plaque-Shaving device shows promise in tiny Leg-Artery study
NCT ID NCT05873452
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This completed study tested a handheld device called the Kaitoh Atherectomy System in 9 people with peripheral artery disease (PAD). The device uses a rotating blade to shave away plaque buildup in leg arteries, aiming to restore blood flow. Researchers checked for safety and how well it worked right after the procedure, and followed participants for 6 months. Because it was a very small early study, more research is needed to know if the device is truly safe and effective.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Kaitoh Atherectomy System (a handheld device that mechanically shaves plaque from artery walls)
- What this could lead to
- If successful, this device could offer a new way to clear blocked leg arteries, potentially improving walking ability and reducing pain for people with peripheral artery disease.
- What could go wrong
- This was a very small early study with only 9 participants, so results may not apply to everyone. The device could cause artery damage, bleeding, or incomplete clearing of blockages.
