FDA Approval for New GORE® EXCLUDER® AAA Endoprosthesis Component

In short

W. L. Gore & Associates, Inc. has received FDA approval to extend the range of its Abdominal Aortic Aneurysm range. Included are the company’s new large diameter 35 mm trunk-ipsilateral leg and 36 mm aortic extender components, as well as the lower profile 31 mm diameter trunk-ipsilateral leg and 32 mm aortic extender components of the GORE® EXCLUDER® AAA Endoprosthesis.


The GORE EXCLUDER AAA Endoprosthesis is an endovascular stent-graft that seals off the aneurysm and creates a new path for blood flow.

Compatible with an 18 Fr GORE® DrySeal Sheath, Gore says the new 35 mm trunk-ipsilateral leg and 36 mm aortic extender represent some of the lowest profiles for treating infrarenal aortic necks measuring up to 32 mm in diameter, expanding the overall treatment range to 19-32 mm. The lower profile 31 mm diameter trunk-ipsilateral leg and 32 mm aortic extender components allow the trunk-ipsilateral leg component to be used with an 18 Fr GORE® DrySeal Sheath and the 32 mm aortic extender component to be used with a 17 Fr compatible sheath to treat aortic necks with an inner diameter of 27-29 mm.

No changes have been made to the GORE EXCLUDER Device itself—instead, Gore has implemented an innovative process using ePTFE materials to constrain the device onto the catheter. This key enhancement to the simple delivery of the device reduces the access vessel requirement (6.8 mm) for patients requiring minimally invasive endovascular AAA repair. As with all of the lower profile devices, the 35 mm trunk-ipsilateral leg endoprosthesis and the 31 mm trunk-ipsilateral leg endoprosthesis are only available with the GORE® C3® Delivery System.

Physician comments

“The expanded sizing options benefit patients and physicians alike. The low profile sheath allows physicians to use the GORE® EXCLUDER® Device on aortic necks measuring up to 32 mm, providing more patients with access to minimally invasive endovascular treatment options using a superior device,” said Scott L. Stevens, MD, Professor, Department of Surgery, University of Tennessee Medical Center.

“While endovascular repair of AAAs has proven to be a successful alternative to open surgical repair, physicians continue to seek improvements to the procedures,” said Fred Weaver, MD, Professor of Surgery at the Keck School of Medicine of the University of Southern California. “This new lower profile 31 mm trunk-ipsilateral leg will expand the treatment options for more patients while continuing to provide flexibility and long-term conformability.”

 Company comments

“Expanding our AAA sizing portfolio means that Gore can now offer physicians a wider range of components using the preferred infrarenal placement on the lowest profile sheath available today,” said Ryan Takeuchi, Gore Aortic Business Leader. “All of our innovative product enhancements, such as the ones announced today, are driven by Gore’s commitment to help physicians provide the best possible patient care.”
