Summary

This completed trial tested a device called CGM MB-1701 to see if it can improve blood flow in people at risk for deep vein thrombosis (DVT). The study enrolled 60 adults who did not have DVT at the start. Researchers measured changes in blood flow speed in the leg vein after using the device for 5 and 10 days.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
CGM MB-1701 blood circulation device
What this could lead to
If it works, this device could help prevent dangerous blood clots in people at risk for deep vein thrombosis.
What could go wrong
This is a small, early-stage trial with only 60 participants. The device may not prove effective or safe in larger, more diverse groups.
