What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a device called RelayPro to help patients with severe tears in their main artery. The device supports the artery from the inside, helping it heal and preventing further damage. RelayPro is a second-generation, low-profile thoracic endograft developed by Terumo Aortic, designed for treating thoracic aortic aneurysm or penetrating atherosclerotic ulcer.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, if you have a blood coagulation disorder, treatment may need to be paused for one week before and after the procedure.

Is the RelayPro Stent-Graft safe for use in humans?

The RelayPro Stent-Graft has been studied for safety in treating various thoracic aortic conditions, including dissections and aneurysms. Research shows it is generally safe, with studies reporting positive safety outcomes in both early and midterm evaluations.12345

What makes the RelayPro Stent-Graft treatment unique for aortic dissection?

The RelayPro Stent-Graft is unique because it is a low-profile device designed specifically for thoracic aortic disease, allowing it to navigate the complex curves of the aorta more easily than some other treatments. This design can improve the safety and effectiveness of the procedure for patients with aortic dissections.12346

What data supports the effectiveness of the RelayPro Thoracic Stent-Graft treatment for aortic dissection?

Research shows that the RelayPro Thoracic Stent-Graft has been evaluated for safety and performance in treating thoracic aortic diseases, including dissections. Studies like the RESTORE II and the Regeneration Study indicate that this treatment is effective and safe for managing conditions similar to aortic dissection.12346

Are You a Good Fit for This Trial?

This trial is for individuals with a recent (within 6 weeks) and severe type B aortic dissection, confirmed by imaging tests. Participants must have specific complications like organ malperfusion or rupture, suitable vascular access for the device, and an anatomy that fits the stent-graft requirements. Exclusions include prior major surgeries in affected areas, unstable heart conditions, severe lung disease requiring oxygen therapy, acute kidney failure not on dialysis, extreme obesity affecting imaging quality, among others.

Inclusion Criteria

My aortic dissection was diagnosed within 6 weeks of symptom onset and is causing severe complications.
The diameter of my aortic neck is between 19 mm and 42 mm.
My arteries are suitable for a specific medical device insertion.
