What this trial studies

This observational study aims to follow patients with intracranial aneurysms who are treated with the Surpass Evolve Flow Diverter System. It is a multi-center, single-arm study that will monitor subjects over a period of up to 8 years, including 5 years of follow-up. Participants will be assessed according to standard care protocols at each study site to evaluate the long-term outcomes of the treatment. The study is designed to gather real-world data on the safety and effectiveness of the device in a clinical setting.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 80 who are eligible for treatment with the Surpass Evolve Flow Diverter System.

Not a fit: Patients with recent treatment of non-target intracranial aneurysms or those with acute aneurysm rupture may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term safety and effectiveness of the Surpass Evolve Flow Diverter System for treating intracranial aneurysms.

How similar studies have performed: While this study follows a well-established treatment approach, the specific observational design and long-term follow-up may provide novel insights into patient outcomes.
