Study Design 
Prospective, non-randomized, multicenter study with four 
independent arms consisting of a total of seven cohorts: 
• 
Zone 2 – Aneurysm, hypothesis-driven analysis 
• 
Zone 2 – Non-aneurysm aortic lesions which are 
anatomically suitable for treatment with the TBE 
Device, descriptive analysis 
o Dissection cohort 
o Traumatic Transection cohort 
o Other isolated lesion types 
 
• 
Zone 0/1 – Aneurysm, hypothesis-driven analysis 
• 
Zone 0/1 – Non-aneurysm aortic lesions which are 
anatomically suitable for treatment with the TBE 
Device, descriptive analysis 
o Dissection cohort 
o Other isolated lesion types 
Study Objective 
Determine whether the GORE® TAG® Thoracic Branch 
Endoprosthesis is safe and effective in treating lesions of 
the aortic arch and descending thoracic aorta  
Study Endpoint(s) 
Primary Endpoint- Zone 2 Subjects (Aneurysm Cohort) 
Composite of the following events from the time of 
enrollment through one year: 
• Device Technical Success 
• Absence of the following: 
o Aortic rupture; 
o Lesion-related mortality; 

o Disabling stroke; 
o Permanent paraplegia; 
o Permanent paraparesis;  
o New onset renal failure requiring permanent 
dialysis; 
o Additional unanticipated post-procedural 
surgical or interventional procedure related 
to the device, procedure, or withdrawal of 
the delivery system. 
 
Primary Endpoint- Zone 0/1 Subjects (Aneurysm Cohort) 
Composite of the following events from time of enrollment 
through one month following endovascular procedure: 
• Initiation of the index endovascular procedure 
following the debranching procedure  
• Device Technical Success for the index endovascular 
procedure 
• Absence of the following: 
o Aortic rupture; 
o Lesion-related mortality; 
o Disabling stroke; 
o Permanent paraplegia; 
o Permanent paraparesis; 
o New onset renal failure requiring permanent 
dialysis; 
o Additional unanticipated post-procedural 
surgical or interventional procedure related 
to the device, procedure, or withdrawal of 
the delivery system. 
Subject Population 
Subjects with thoracic aortic lesions which require coverage 
of the left subclavian artery, left common carotid artery 
and/or the brachiocephalic trunk/innominate artery for 
effective treatment. 
Number of Subjects 
Total Enrollment of 175-465 Subjects across four 
independent arms with a total of seven cohorts as follows: 
• 
Zone 2 – Aortic Aneurysm; A maximum of 115 
Subjects 
o Primary Enrollment (n=85 Subjects) 
o Continued Access Enrollment (maximum 30 
Subjects) 
• 
Zone 2 – Non-aneurysm aortic lesions; A maximum 
of 200 Subjects in all cohorts combined. 
o Dissection cohort (minimum 20 Subjects) 
o Traumatic Transection cohort (minimum 10 
Subjects) 
o Other isolated lesion types 

• 
Zone 0/1 – Aortic Aneurysm; 50 Subjects 
• 
Zone 0/1 – Non-aneurysm aortic lesions; A 
maximum of 100 Subjects in all cohorts combined.  
o Dissection cohort (minimum 10 Subjects) 
o Other isolated lesion types 
Number of Sites 
Up to 40 sites in the U.S. (Zone 2 and Zone 0/1) and up to 5 
sites in Japan (Zone 0/1).
