About

This study will assess the initial feasibility of the GORE® EXCLUDER® Thoracoabdominal Branch Endoprosthesis (TAMBE Device) in the treatment of Aortic Aneurysms Involving the Visceral Branch Vessels.

Full description

This is a prospective, non-randomized study designed to assess the feasibility of the TAMBE Device in the treatment of patients with aortic aneurysms involving the visceral branch vessels. A maximum of 10 Subjects will be treated under this Protocol. This clinical study will include up to six sites in the US. Each enrolled subject will undergo periodic follow-up evaluations involving physical exams, contrast-enhanced computed tomography (CT) of chest, abdomen and pelvis, creatinine measurement, abdominal ultrasound (optional) at specific, protocol-defined intervals for a period of five years following the GORE® EXCLUDER® Thoracoabdominal Branch Endoprosthesis implant.

Enrollment: 10 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

5. Male or infertile female
6. The patient is considered high risk for open repair as deemed by the treating physician
7. Capable of complying with protocol requirements, including follow-up
8. An Informed Consent Form signed by Subject or legal representative Note: Additional Inclusion Criteria may apply

Exclusion criteria

1. Prior aortic surgery
2. Ruptured or leaking aortic aneurysm
3. Aneurysmal dilatation due to chronic aortic dissection
4. Infected aorta
5. Mycotic aneurysm
6. Life expectancy <2 years
7. Myocardial infarction or stroke within 6 weeks of treatment
8. Systemic infection which may increase risk of endovascular graft infection
9. Degenerative connective tissue disease, e.g. Marfan's or Ehler-Danlos Syndrome
10. Participation in another drug or medical device study within 1 year of study enrollment
11. History of drug abuse, e.g. cocaine or amphetamine or alcohol, within 1 year of treatment
12. Tortuous or stenotic iliac and / or femoral arteries and the inability to use a conduit for vascular access
13. Known sensitivities or allergies to the device materials
14. Previous instance of Heparin Induced Thrombocytopenia type 2 (HIT-2) or known hypersensitivity to heparin
15. Patient has body habitus or other medical condition which prevents adequate fluoroscopic and CT visualization of the aorta
16. Renal Insufficiency Note: Additional Exclusion Criteria may apply

Description:

Study designed to assess the feasibility of the GORE® EXCLUDER® Thoracoabdominal Branch Endoprosthesis (TAMBE Device) in the treatment of patients with aortic aneurysms involving the visceral branch vessels. Patients with thoracoabdominal or pararenal abdominal aortic aneurysms are eligible for screening for participation in the study. The particular characteristics of the patient's aneurysm and anatomy will determine ultimate eligibility for enrollment. Only patients who meet all of the eligibility criteria will be enrolled.
