Abdominal Aortic and Junctional Tourniquet - Stabilized™

Abdominal Aortic & Junctional Tourniquet – Stabilized

AAJT-S™ is an innovative, life-saving device that provides stable and complete occlusion of blood flow to the lower extremities, pelvis, and upper extremities.

Solution for Junctional Hemorrhages and Pelvic Hemorrhages

AAJT-S™ is proven to be effective at stopping hemorrhage in the axilla and groin.

The only truncal tourniquet available

Proven to stop pelvic bleeding from blunt or penetrating trauma

Proven equivalent to Zone 3 REBOA

Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) technique requires placing a flexible catheter into the femoral artery, navigating it to the aorta and inflating a balloon at its tip.

Research has shown that the AAJT-S™ capabilities are equivalent to REBOA  in Zone 3 of the aorta, while the invasive risks of the REBOA procedure are eliminated and no medical background is needed to use the device.
