Zenith Alpha Thoracic Endovascular Graft Proximal Tapered Component (ZTA-PT)
The Zenith Alpha Thoracic Endovascular Graft is designed for treating descending thoracic aortic aneurysms or ulcers in patients with suitable vascular anatomy. Key requirements include accessible iliac/femoral vessels for device introduction and nonaneurysmal aortic segments (≥20 mm in length, 20–42 mm in diameter) for proximal and distal fixation.

The Zenith Alpha Thoracic Endovascular Graft is indicated for the endovascular treatment of patients with aneurysms or ulcers of the descending thoracic aorta having vascular morphology suitable for endovascular repair, including:
- Iliac/femoral anatomy that is suitable for access with the required introduction systems
- Nonaneurysmal aortic segments (fixation sites) proximal and distal to the thoracic aneurysm or ulcer with a length of at least 20 mm, and with a diameter measured outer-wall-to-outer-wall of no greater than 42 mm and no less than 20 mm
