Zenith® Iliac Branch

The Zenith Iliac Branch, when used with the necessary additional components (Zenith AAA devices and a covered bridging stent), is indicated for endovascular treatment of aortoiliac or iliac aneurysms to preserve internal iliac arterial blood flow when the distal sealing site in the common iliac artery is insufficient for the AAA device alone and when the vessel morphology is suitable for repair, including

• Common iliac artery diameter at the level of the internal iliac artery (luminal diameter) ≥16 mm 
• Adequate iliac/femoral access compatible with a 20 Fr (7.7 mm O.D.) introduction system 
• Non-aneurysmal external iliac artery fixation segment distal to the aneurysm:
  — With a length of at least 20 mm
  — With a diameter measured outer wall to outer wall of no greater than 11 mm and no less than 8 mm 
• Non-aneurysmal internal iliac artery segment distal to the aneurysm:
  — With a length of at least 10 mm (with 20–30 mm being preferred)
  — With a diameter measured outer wall to outer wall no greater than 10 mm and no less than 7 mm.
