New hydrophilic delivery system offers AAA treatment benefits for US patients

Medtronic : 10 January, 2008  (New Product)
Medtronic's AneuRx AAAdvantage Stent Graft on the new Xcelerant Hydro Delivery System is to be launched in the USA.
The new product features a hydrophilic coating designed to aid navigation of the device through tight and tortuous arteries by reducing friction with the artery wall.

Medtronic has also received approval from the US Food and Drug Administration to introduce its latest generation of packaging materials for the launch of this product.

“The Xcelerant Hydro Delivery System is a significant innovation that will make endovascular repair using the AneuRx AAAdvantage Stent Graft a treatment option for more patients with abdominal aortic aneurysms,” said Dr Frank R Arko, MD, chief of endovascular surgery at the University of Texas Southwestern Medical Center in Dallas, USA. “It will simplify the procedure for endovascular interventionalists in treating patients whose iliac arteries are difficult to navigate when they are small and tortuous.”

The Xcelerant Hydro Delivery System will be used with the AneuRx AAAdvantage Stent Graft, which was introduced in the USA in March 2006. In bench testing, the Xcelerant Hydro Delivery System was shown to generate 68 times less friction than the previous delivery system, which does not have the hydrophilic coating. The hydrophilic coating is designed to ease the delivery system’s passage through the artery.

In addition, the Xcelerant Hydro Delivery System features an integrated sheath that is tapered on both ends. This dual-taper sheath is designed to facilitate insertion and retraction of the entire delivery Catheter by minimising the time that the surface area of the sheath is in contact with the artery wall. The integrated sheath also contributes to the system’s low profile characteristics, which enables tracking and access through small vessels.

“Experience remains the foundation of our innovations in endovascular therapy, and the Xcelerant Hydro Delivery System represents our latest innovative contribution to this exciting field,” said Katie Szyman, vice president and general manager of Medtronic’s Endovascular Innovations business. “Combined with the AneuRx AAAdvantage Stent Graft, Medtronic now offers US endovascular physicians an even stronger option for their EVAR procedures.”
