Cook Medical Launches Zenith Low Profile Endovascular Graft in Canada

Canadian market’s lowest profile device enables treatment of abdominal aortic aneurysms (AAA) in patients with small access vessels

January 31, 2012 — Following Health Canada approval, the Zenith Low Profile AAA Endovascular Graft (Zenith AAA LP) from Cook Medical is now approved and will be launched to physicians in Canada. With a low-profile delivery system diameter of 18 French and simplified deployment compared to previous Zenith endograft systems for precise delivery of the graft to the desired position in the patient's aorta.

“Compared to previous Cook devices, the Zenith LP graft's low profile system expands the patient population eligible for endovascular aneurysm repair, enabling us to treat patients with small access vessels who might otherwise have to have a conduit procedure for endovascular access. The stent system features barbs, a suprarenal stent, and provides excellent deployment accuracy.  Zenith LP’s 16 French system gives us more reassurance for doing percutaneous endovascular aneurysm repair (EVAR) as well,” said Cherrie Abraham, M.D., vascular and endovascular surgeon with Jewish General Hospital and McGill University.  

Cook will continue offering its existing Zenith Flex AAA endograft system in addition to the new Zenith AAA LP as part of its ongoing commitment to improved patient outcomes by offering products that are best-suited to the individual needs of every patient.

Cook's new Zenith AAA LP device has a significantly smaller profile than their other EVAR delivery systems, which measure 20-24 French. The newly engineered stent-graft is based on Cook Medical's ARC technology, which combines a series of barbs that engage the aortic wall to provide active fixation, radial force from self-expanding z-stents for stability and optimal graft-to-vessel apposition, and a long main body with columnar strength.

While larger EVAR systems must use a surgical incision to access the femoral artery, in some patients the Zenith AAA LP can be inserted into the femoral artery percutaneously. With this approach both the wire guide and delivery sheath are introduced by a needle inserted into the blood vessel through the skin. This procedure allows aortic access without the need for a surgical cut-down of the artery.

The Zenith AAA Low Profile AAA Graft is an investigational device not approved for sale in the United States.
