About This Study
Summary
To evaluate the safety and effectiveness of the NEXUS™ Aortic Arch Stent Graft System for the endovascular treatment of thoracic aortic lesions involving the aortic arch, including chronic dissections, aneurysms, penetrating aortic ulcers and intramural hematoma.
To be included in TRIOMPHE, participants must be / have
- Male and female age ≥ 18
- Proximal/ascending native or previously implanted surgical graft landing zone length ≥ 30 mm
- Proximal/ascending native landing zone diameter: 30 ≤ ø ≤ 39 mm or surgical graft landing zone diameter: 26 ≤ ø ≤ 39 mm
- Distal/descending native landing zone length: ≥ 30 mm
- Distal/descending native landing zone diameter of:
- a. 26 ≤ ø ≤ 40 mm for aneurysms, PAU and IMH
- b. 28 ≤ ø ≤ 42 mm for chronic dissection
To be included in TRIOMPHE, participants must not be / have
- Acute dissection
- Lesions that can be safely treated with TEVAR landing in zone 2 (with or w/o LSA vascularization)
- Required emergent treatment, e.g., trauma, rupture
- Acute vascular injury of the aorta due to trauma
- Aortic rupture or unstable aneurysm
- Received a previous stent or stent graft in the treated area (including planned landing area)
CAUTION: Investigational Device – Limited by United States law to investigational use. Endospan devices bear the CE marking of conformity.
