W. L. Gore & Associates, Inc. has gained U.S. FDA approval for its GORE® EXCLUDER® Iliac Branch Endoprosthesis (IBE), making it the first off-the-shelf aortic branch device approved in the United States and the only device indicated for the endovascular treatment of common iliac artery aneurysms or aortoiliac aneurysms.
The first-of-its-kind device, Gore’s Excluder is a complete, fully engineered system, which received CE Mark in 2013 as we reported at the time.
The device is used 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 built on Gore’s technology platform and designed using the same durable, expanded polytetrafluoroethylene (ePTFE) graft and nitinol stent material.
The IBE offers an All-in-One System and can claim improved outcomes for the treatment of iliac artery aneurysms while preserving flow to the iliac arteries. Preservation of blood flow in the internal iliac arteries is found to avoid pelvic flow disruption and reduce the rate of buttock claudication, sexual dysfunction, and colonic ischemia.
The IBE system provides a treatment range of 6.5-13.5 mm for the internal iliac arteries, and a treatment range of 6.5-25 mm for the external iliac arteries. The delivery profile of the loaded catheter allows the use of a 16 Fr introducer sheath for the iliac branch component, and a flexible 12 Fr, reinforced introducer sheath for the internal iliac component.
The GORE EXCLUDER Iliac Branch Device Clinical Study, a prospective, multicenter, non-randomized, single-arm study designed to assess the safety and effectiveness of the IBE in treating common iliac artery aneurysms or aortoiliac aneurysms, completed enrollment in February 2015. A total of 62 patients received the device, which met the FDA required enrollment of 60 patients. The trial also enrolled an additional 32 patients through Continued Access (as of February 15, 2016), which expanded treatment options to allow for bilateral placement of the IBE in addition to unilateral IBE device placement, which was evaluated in the Primary Enrollment.
“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 percent of AAA cases,” said Gore consultant, Darren Schneider, MD, Chief of Vascular and Endovascular Surgery and associate professor of surgery at Weill Cornell Medicine and Principal Investigator for the national GORE EXCLUDER Iliac Branch Device Clinical Study. “However, 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.”
“FDA approval of this device is extremely important as it provides an iliac branch solution for a patient group with a previously unmet treatment need,” said Ryan Takeuchi, Gore Aortic Business Leader. “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. 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.”
