What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a device called the Surpass™ Evolve Flow Diverter System, which helps treat specific brain aneurysms in adults by redirecting blood flow to prevent them from bursting. The Surpass flow diverter is a new system under evaluation in the USA, designed to treat large and giant aneurysms.

Do I need to stop my current medications to join the trial?

The trial does not specify if you need to stop your current medications, but it mentions that you cannot participate if you have a medical contraindication to antiplatelet medications or are on chronic anticoagulation therapy. It's best to discuss your current medications with the trial team.

How is the Surpass Evolve Flow Diverter treatment different from other treatments for brain aneurysms?

The Surpass Evolve Flow Diverter is unique because it is a new generation device specifically designed to redirect blood flow away from brain aneurysms, promoting healing. It is particularly effective for treating small, distal cerebral artery aneurysms, offering a low-profile option that may be safer and more effective than other flow diverters.12345

Are You a Good Fit for This Trial?

This trial is for adults aged 18-80 with unruptured, wide-neck brain aneurysms ≤12 mm on the internal carotid artery or branches. Candidates should have a higher risk of rupture if untreated and no severe allergies to materials used in the procedure. Exclusions include recent major surgery, ongoing anticoagulation therapy, other serious medical conditions, pregnancy, or enrollment in another investigational product trial.

Inclusion Criteria

I have one unruptured brain aneurysm on the internal carotid artery or its branches.
Doctors believe treating my brain aneurysm with a procedure is safer than leaving it untreated.
My aneurysm is ≤ 12 mm, with specific neck and vessel size requirements.

What Are the Treatments Tested in This Trial?

Interventions

  • Surpass Evolve Flow Diverter System
Trial Overview The Surpass Evolve Flow Diverter System is being tested for safety and effectiveness in treating small unruptured brain aneurysms. The device aims to divert blood flow away from the aneurysm to prevent rupture. Participants will be selected based on specific aneurysm characteristics and must not have had prior treatments that could interfere with this device.
