Iliac Branch System Helps Control Aneurysms

A novel all-in-one system helps preserve iliac artery blood flow in patients with common iliac artery aneurysms or aortoiliac aneurysms.

The Gore Excluder Iliac Branch Endoprosthesis (IBE) is a complete, fully engineered system that includes iliac branch and internal iliac components. The device is intended for use in conjunction with the Gore Excluder AAA Endoprosthesis to isolate the common iliac artery from systemic blood flow, and preserve blood flow in the external iliac and internal iliac arteries. The device is made of durable expanded polytetrafluoroethylene (ePTFE) graft material and a nitinol stent, similar to the AAA Endoprosthesis.


The IBE device offers a wide internal iliac artery treatment range of 6.5 to 13.5 mm, and is repositionable to precisely place the iliac component. It is installed using a delivery catheter and 16 French introducer sheath in the case of the iliac branch component, and a 12 French introducer sheath in the case of the internal iliac component. The Gore Excluder IBE is a product of Gore Medical Products (Flagstaff, AZ, USA), and has been approved by the US Food and Drug Administration (FDA).

“The Gore Excluder iliac branch device has demonstrated high patency, conformability, and durability, and provides physicians with an on-label, minimally invasive method of preserving flow to the internal and external iliac arteries,” said Ryan Takeuchi, aortic business leader at Gore Medical Products (Flagstaff, AZ, USA). “Not only is IBE the first off-the-shelf aortic branch device approved in the United States, it is a part of a complete portfolio of aortic branch solutions that are currently in clinical evaluation.”

“Historically, options to preserve flow to the internal iliac arteries during endovascular aneurysm repair were very limited, despite the involvement of the iliac arteries in about 25% of AAA cases,” said Darren Schneider, MD, chief of vascular and endovascular surgery at Weill Cornell Medical College (New York, NY, USA). “Through our research and the subsequent FDA approval, physicians now have a new therapeutic option to preserve pelvic perfusion in order to improve clinical outcomes and maintain patient quality of life.”

Preservation of blood flow in the internal iliac arteries avoids pelvic flow disruption and reduces the rate of buttock claudication, sexual dysfunction, and colonic ischemia.
