New leg sleeve aims to stop deadly clots – but does it work?
NCT ID NCT07287007
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new device called VenAir that squeezes the legs to improve blood flow and prevent blood clots. About 105 healthy adults aged 20-64 will lie down while wearing different leg garments, and ultrasound will measure their blood flow. The goal is to see if VenAir works as well as a standard device already on the market.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- VenAir intermittent pneumatic compression device
- What this could lead to
- If it works, this could provide a new option for preventing dangerous blood clots in the legs and lungs.
- What could go wrong
- This is an early study in healthy people, not patients. It only measures blood flow, not actual clot prevention, so success here doesn't guarantee it prevents clots in real-world use.
