| Usage | The stent grafts fabricated from medical implant-grade ePTFE tubing are primarily used in minimally invasive endovascular surgical procedures. Their usage involves: 1. Percutaneous Delivery: The stent graft is compressed and pre-loaded into a catheter-based delivery system. 2. Navigation to Target Site: Under fluoroscopic guidance, the delivery system is navigated through the vascular system (e.g., via the femoral artery) to the diseased or injured site, such as an aneurysm, dissection, or stenosis. 3. Deployment and Sealing: Once precisely positioned, the stent graft is deployed. The self-expanding or balloon-expandable stent component provides radial force to secure the device in place and open the lumen. The ePTFE tubing (graft component) then acts as a new, sealed conduit for blood flow, excluding the pathological segment from circulation and preventing rupture or further damage. |
| Main features | The main features of these ePTFE-based stent grafts are derived from the unique properties of the material and the fabrication process: 1. Exceptional Biocompatibility: As a medical implant-grade material, ePTFE is inert and non-toxic, minimizing adverse immune responses and promoting long-term tissue acceptance. 2. Controlled Microporous Structure: ePTFE has a node-and-fibril microstructure. This porosity can be engineered during fabrication to discourage blood clot formation (thromboresistance) while allowing for controlled tissue ingrowth for stable integration. 3. Chemical Inertness and Stability: ePTFE is highly resistant to chemical degradation within the body, ensuring the long-term structural integrity of the graft without biodegradation. 4. High Strength and Flexibility: The material offers an excellent strength-to-weight ratio and is highly flexible, enabling the fabrication of kink-resistant grafts that can withstand cyclic stresses and conform to complex vascular anatomy. 5. Suture Retention Strength: The ePTFE tubing can be manufactured or processed to have high suture retention strength, which is crucial for securing the graft during open surgical procedures or for attaching additional components. 6. Hemocompatibility: The smooth, non-thrombogenic surface of ePTFE minimizes platelet adhesion and activation, reducing the risk of thrombosis within the graft. |
| Application | Stent grafts made from ePTFE tubing are critically used in the treatment of various vascular diseases across different parts of the body: 1. Aortic Aneurysm Repair: * Abdominal Aortic Aneurysm (AAA): The most common application, using an ePTFE stent graft to line the aorta and exclude the aneurysm. * Thoracic Aortic Aneurysm (TAA): Used to repair aneurysms in the chest cavity. 2. Traumatic Vascular Injury: To seal punctures or tears in major blood vessels caused by trauma. 3. Peripheral Arterial Disease: * Iliac Artery Disease: Treating aneurysms or occlusions in the iliac arteries. * Femoropopliteal Bypass: Used as a synthetic bypass graft in the legs when a saphenous vein is unavailable. 4. Arteriovenous Access (AV Fistula): For patients requiring hemodialysis, ePTFE grafts can be surgically created to connect an artery to a vein, providing a durable and accessible site for repeated needle punctures. 5. Treatment of Aortic Dissections: To cover the primary entry tear and restore true lumen blood flow. 6. Venous Applications: Less commonly, for treating major venous obstructions or stenoses. |
