Testing a New Stent Graft for Aortic Arch Tears

This trial is testing a new medical device called the Aortic Arch Single Branch Covered Stent System, which is designed to repair a serious condition where the inner lining of the aorta (your body's main artery) tears in the aortic arch region. The stent graft is placed through blood vessels using a minimally invasive procedure, rather than open surgery. Researchers want to see if this new device is safe and effective for patients who need repair in this specific area and also need to protect an important artery called the left subclavian artery.

Standard treatments for aortic arch dissection can be challenging and carry significant risks. This trial exists to evaluate whether this newer branched stent graft approach offers a safer, more effective alternative that can treat the dissection while keeping blood flowing to the left subclavian artery at the same time.
