This study tests a special device called the GORE® EXCLUDER® Thoracoabdominal Branch Endoprosthesis (TAMBE) to treat aortic aneurysms. An aortic aneurysm is a bulge in the wall of the aorta, the large blood vessel that carries blood from your heart. There are two parts to this study: the Primary Study Arm and the Secondary Study Arm. The primary arm focuses on aneurysms that can be treated with just the TAMBE system, while the secondary arm involves using both the TAMBE and another device called the CTAG for more complex aneurysms. Participants need to meet specific health criteria to join the study, and the study will involve 122 to 202 people. The study is prospective, meaning it will follow patients over time to see how effective the treatment is.

• The study is non-randomized, meaning participants are not randomly assigned to a treatment group.
• Participants must be at least 19 years old and able to follow study procedures.
• The study involves close monitoring and requires participants to meet specific health conditions.
