What is the Medtronic Valiant Navion Thoracic Stent Graft?
The Valiant Navion is the third and latest generation of thoracic and endovascular aortic repair (TEVAR) in a single system, with covered and bare stent options. The stent system is designed to treat a wide range of patient anatomies and all lesions of the descending thoracic aorta (DTA), including thoracic aortic aneurysms (TAA), Type B aortic dissection (TBAD), intramural hematoma (IMH), penetrating atherosclerotic ulcer (PAU), and blunt thoracic aortic injury (BTAI). Approximately 14,000 people worldwide are implanted with the stent system.
How does the device work?
The system uses a delivery catheter containing the endovascular stent graft to insert a blood vessel (femoral artery) in the groin through a small cut. After being placed in the artery, the stent-graft expands and relieves the pressure on your aorta by providing a new pathway for blood flow. The Valiant Navion Thoracic Sent Graft System is used in surgeries involving a small cut in the groin instead of a bigger cut in the chest for minimal invasiveness. It intends to prevent the growth and rupture of lesions on patients’ aortas.
