💬In plain words
What the trial is, and whether it could suit you
The goal of this clinical trial is to evaluate the safety and feasibility of the Cygnum Aneurysm Sac Management Device in patients with abdominal aortic aneurysms treated with endovascular aneurysm repair (EVAR). The main questions it aims to answer are:
1. Is the Cygnum device safe when used adjunctively with standard EVAR endografts?
2. Does it effectively reduce or prevent type II endoleaks by managing the aneurysm sac?
Participants will:
1. Undergo EVAR with adjunctive implantation of the Cygnum device
2. Have follow-up imaging (e.g., CT scans) and clinical assessments to evaluate device position and sac behavior over time
