Medtronic Launches Stent Graft on New Delivery System for AAA
Medtronic Inc. offers the AneuRx AAAdvantage Stent Graft on the new Xcelerant Hydro Delivery System, expanding its product line in endovascular therapies for aortic aneurysms.
The Xcelerant Hydro Delivery System features a hydrophilic coating designed to aid navigation of the device through tight and tortuous arteries by reducing friction with the artery wall. The system will be used with the AneuRx AAAdvantage Stent Graft, which was introduced in the United States 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.
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 minimizing 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 are intended to optimize tracking and access through small vessels.
