What is an Amplatzer plug?
The Amplatzer Vascular Plug (AVP) is an established embolic device that can be an excellent alternative to coils or detachable balloons to embolize medium to large vessels with high flow.
What is a vascular plug?
Vascular plugs are ideal for embolization of medium to large vessels with high flow. These vascular structures are often closed using a single AVP that otherwise would have required many coils. Thus, AVPs are efficient and a cost-effective alternative to coils and other occlusion devices.
What is a Amplatzer duct occluder?
The Amplatzer Duct Occluder (AGA Medical Corporation, Golden Valley, MN) is a self-expanding and self-centering device, made from 0.0004 to 0.0005 inch Nitinol wire mesh. It is mushroom-shaped with a low profile and consists of a flat retention disk and a cylindrical main body, into which polyester fibers are sewn.
How do vascular plugs work?
Amplatzer™ Vascular Plugs (AVP) Mechanism of Action The nitinol mesh of an AVP acts as an embolic agent that promotes rapid clot formation. Each AVP creates a physical barrier to blood flow by instigating both the body’s immune response followed by a natural coagulation process.
How do coils stop bleeding?
During a coiling procedure, a catheter is inserted into the aneurysm and coils are packed inside the dome. Coils promote blood clotting, which closes off the aneurysm and eliminates the risk of rupture.
How does Amplatzer duct occluder work?
The AMPLATZER™ Duct Occluder is a percutaneous, transcatheter occlusion device intended for the nonsurgical closure of a patent ductus arteriosus (PDA). The device should be removed if greater than 3 mm extends into the pulmonary artery, or if more than half of the left pulmonary artery lumen is occupied by the device.
How do you close a patent ductus arteriosus?
In a catheter procedure, a thin tube (catheter) is inserted into a blood vessel in the groin and threaded up to the heart. Through the catheter, a plug or coil is inserted to close the ductus arteriosus. If the procedure is done on an outpatient basis, you or your child probably won’t stay overnight in the hospital.
Is Amplatzer vascular plug MRI safe?
Magnetic resonance imaging (MRI) scans are generally acceptable, and your AMPLATZER PFO Occluder is compatible with imaging when using a 3-tesla MRI. If an MRI is needed, simply inform the MRI staff about your implant.
What is a plug embolization?
Abstract. The Amplatzer Vascular Plug (AVP) was created for peripheral embolization as a modification of the family of Amplatz septal occluders used in the treatment of congenital heart malformations. The device has evolved over the years and multiple versions have been launched into the market.
How do vascular coils work?
During endovascular coiling, a catheter is passed through the groin up into the artery containing the aneurysm. Platinum coils are then released. The coils induce clotting (embolization) of the aneurysm and, in this way, prevent blood from getting into it.
How long can you live with a coiled brain aneurysm?
Patients whose aneurysms are coiled instead of clipped have a better survival rate over five years according to a long-term study of the International Subarachnoid Aneurysm Trial (ISAT).
What is Amplatzer duct occluder?
How are Amplatzer vascular plugs designed to work?
The single lobe design of the Amplatzer Vascular Plug provides a device length appropriate for short vessel landing zones. Amplatzer Vascular Plugs are designed to provide optimal embolization of peripheral veins and arteries through single device occlusion, full cross-sectional vessel coverage, controlled and precise deployment.
What kind of vascular plug does AGA Medical use?
