Gore Releases Longer Vascular Graft

Published November 15, 2012
W.L. Gore & Associates Inc. has released the 10-centimeter configuration for its hybrid vascular graft. The new size is designed to access deeper vessels, which expands treatment and makes it easier for physicians performing vascular procedures, the company claims.

The graft is used as a vascular prosthesis for replacement or bypass of diseased vessels in patients suffering occlusive or aneurysmal diseases, in trauma patients requiring vascular replacement, for dialysis access, or for other vascular procedures.

The new configuration features a 10-centimeter durable nitinol-reinforced section that is double the length of the existing 5-centimeter graft. Besides being able to access deeper vessels, the graft reportedly can create new access sites in anatomical locations that would otherwise have been abandoned, preserving the number of access sites available throughout a patient’s long-term therapy.

“The new 10-centimeter nitinol-reinforced section of the Gore hybrid vascular graft extends the value of the device by providing minimally invasive access to those vessels that may not have been reachable without major surgery,” said John R. Ross, M.D., general surgeon at Regional Medical Center in Orangeburg, S.C., who recently performed the first implants of the new 10-centimeter device for dialysis access. “This preserves valuable real estate and provides an ability to revise sites that otherwise would have been abandoned. This is an especially important new option for the dialysis access population.”

“By integrating a longer nitinol-reinforced section into the design of the new hybrid graft, we are able to access even more difficult-to-reach vessels from more proximal sites, thereby expanding our patients’ treatment options,” added Jen Ash, M.D. Ash was part of a team from the Division of Vascular and Endovascular Surgery at HeartCare Midwest Department of Surgery, University of Illinois College of Medicine in Peoria, Ill., that performed the first arterial bypass procedure in the lower limb using the 10-centimeter configuration of the graft. The other team members were Syed Hussain, M.D. and Nabeel Rana, M.D.

The Gore hybrid vascular graft also offers several advantages for visceral and renal bypasses, noted Jean Bismuth, M.D., vascular surgeon at The Methodist Hospital in Houston, Texas. “This device provides a distinct advantage in renal bypasses by allowing for a rapid and reliable anastomosis, thereby minimizing renal ischemia,” Bismuth said. “Additionally, in visceral and renal bypasses, it permits the surgeon to address the anastomosis and atherosclerotic disease of the vessel simultaneously, optimizing flow.”

The original Gore hybrid vascular graft was launched in the United States in May 2011 and in Europe in August 2012.
