Product Name: OVATION Abdominal Stent Graft System
PMA Applicant: Trivascular, Inc.
Address: 3910 Brickway Blvd., Santa Rosa, CA 95403
Approval Date: October 5, 2012
Approval Letter: http://www.accessdata.fda.gov/cdrh_docs/ pdf12/P120006a.pdf
What is it? The OVATION Abdominal Stent Graft System is used to treat abdominal aortic aneurysms during endovascular repair (EVAR). An aneurysm is a diseased, bulging, weak section of an artery wall; in this case the aorta. The main portion of the OVATION Abdominal Stent Graft is made of a plastic tube supported partially by polymer-filled rings and partially by a metallic stent. The OVATION Abdominal Stent Graft is compressed into the end of a long, thin, tube-like device called a delivery catheter.
How does it work? The delivery catheter containing the stent graft is inserted into the femoral artery in the groin through a small skin incision. It is carefully guided within the artery into the abdomen to bridge the site of the aortic aneurysm. The stent graft is then released and it self-expands to the diameter of the aorta. The polymer-filled rings enable the stent graft to conform to the vessel wall. The stent graft then redirects the blood flow away from the aneurysm and it relines the artery wall. This can prevent further growth and possible rupture of the aneurysm.
When is it used? The OVATION Abdominal Stent Graft System is used instead of a more open (invasive) surgery in patients who have an abdominal aortic aneurysm.
What will it accomplish? Over time, the wall of an untreated aneurysm may weaken under the force of blood pressure, causing the aneurysm to rupture, which can be life-threatening. The OVATION Abdominal Stent Graft System should benefit patients with an abdominal aneurysm by redirecting blood flow, preventing growth or rupture of the aneurysm.
When should it not be used? The OVATION Abdominal Stent Graft System should not be used in patients who:
- are unable to undergo the necessary preoperative and postoperative imaging and implantation studies.
- have an infection that might threaten to infect the stent graft.
- are sensitive to, or allergic to the device materials.
