Surgical Stent

Cardinal Health, Inc.Stent Graft System is for the treatment of abdominal aortic aneurysms. An abdominal aortic aneurysm is a bulge in the wall of an artery, which is almost always caused by cellular changes due to arteriosclerosis

During surgical repair with Cardinal Health, Inc.Stent Graft System, the incision is made in each groin and the stent graft is inserted by a delivery catheter into the femoral artery and guided through the aorta to the aneurysm site. Once placed, the stent graft expands to fit within the diameter of the aorta, providing a new path for blood flow and reducing the pressure on the aneurysm. Once the stent graft is placed, the catheter is withdrawn.

The system's self-expanding, diamond shaped, nickel-titanium stent rings are designed for self-anchoring to the vessel wall by "friction fit," without the need to puncture the vessel with hooks or barbs. The stent graft also is designed to adapt to individual patient anatomies. Extender cuffs may be used to modify the length and/or diameter of the implanted graft. Additionally, the stent graft's fully supported exterior is designed to prevent kinks or twisting and device migration over time, which can lead to the need for open repair.
