Summary

This study tests a non-invasive device called the AAJT-S, which is placed over the upper belly and inflated to temporarily stop blood flow to the pelvis. It is being used for 20 women with severe postpartum hemorrhage that does not respond to standard treatments like medication or a balloon. The goal is to see if it can stop visible bleeding within 5 minutes and to check for any device-related side effects.

What this could mean

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

Active substance: Abdominal Aortic and Junctional Tourniquet (AAJT-S) device
What this could lead to: If it works, this device could provide a fast, non-surgical way to control life-threatening postpartum bleeding, potentially saving lives in emergency settings.
What could go wrong: This is a very small early study (20 people) testing a temporary measure. The device may not stop bleeding quickly enough, and there are risks of complications from reduced blood flow to organs.
