  15. Significant thrombus or atheroma in the aortic arch
  16. Tortuous or stenotic iliac and/or femoral arteries preventing introducer sheath insertion and the inability to use a conduit for vascular access
  17. Planned coverage of celiac artery
  18. Patient has known sensitivities or allergies to the device materials
  19. Patient has known hypersensitivity or contraindication to anticoagulants or contrast media, which is not amenable to pre-treatment
  20. Previous instance of Heparin Induced Thrombocytopenia type 2 (HIT-2) or known hypersensitivity to heparin
  21. Diameter taper outside of the device sizing range between proximal and distal landing zones of aorta and the inability to use additional devices of different diameters to compensate for the taper
  22. Mycotic aneurysm
  23. Persistent refractory shock (systolic blood pressure <90 mm Hg)
  24. Patient has body habitus or other medical condition which prevents adequate visualization of the aorta

Arm Type

Experimental

Arm Label

Branched TAG® Device

Arm Description

Treatment with the GORE® TAG® Thoracic Branch Endoprosthesis

Outcomes

Primary Outcome Measures

Number of Participants With Successful Study Device Access
Access to the aneurysm and target landing zone location is obtained via conventional vascular access and endovascular techniques.
Number of Participants With Successful Study Device Deployment
Absence of deployment failure will be considered a successful deployment. Deployment failure will be considered the failure of any Branched TAG® Device component (Aortic Component, Aortic Extender, or SB Component) to be released from the delivery catheter resulting in a serious adverse event (SAE) due to mechanical failure or use error.
Number of Participants With Primary Procedural Side Branch Patency
The presence of forward flow through the implanted Side Branch Component into the target branch vessel.

Secondary Outcome Measures

Number of Participants With 1 Month Side Branch Primary Patency Assessed by an Independent Core Lab
Number of Participants Without 1 Month Device Related Endoleaks Assessed by an Independent Core Lab
Device-related endoleaks are defined as the presence of contrast within the aneurysm sac originating from the junction between any Branched TAG® Device component and the landing zone (Type IA or IB) or the junction between the Aortic Component and either the Side Branch Component or the Aortic Extender (Type III).

5. Study Description

Brief Summary
The purpose of this study is to assess the early feasibility of the use of the GORE® TAG® Thoracic Branch Endoprosthesis to treat aneurysms involving the aortic arch
Detailed Description
The GORE® TAG® Thoracic Endoprosthesis (TAG® Device) received premarket approval (PMA) for use in endovascular aneurysm repair of the descending thoracic aorta (DTA) on 23-Mar-2005 under P040043, and design changes that resulted in the conformable GORE® TAG® Thoracic Endoprosthesis (CTAG) received premarket approval for the treatment of aneurysms of the DTA on 23-Aug-2011 (P040043/S039). The TAG® Device and CTAG are intended to exclude an aneurysm from the blood circulation in patients diagnosed with DTA aneurysms. However, endovascular treatment options for patients with aortic arch aneurysms are limited as current stent graft technology would require coverage of aortic arch vessels. This prompted the creation of the GORE® TAG® Thoracic Branch Endoprosthesis (previously known as Branched TAG® Device), which was being evaluated under IDE G130120 for Zone 2 aneurysms when this clinical investigation was initiated to evaluate the GORE® TAG® Thoracic Branch Endoprosthesis for the treatment of Zone 0 and Zone 1 aneurysms of the aortic arch.
