What is a AMPLATZER vascular plug?

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.

What is a vascular plug 4?

Device Description The AMPLATZER™ Vascular Plug 4 is a self-expanding nitinol mesh occlusion device. The device has a radiopaque marker band at each end and a micro screw attachment at one end for attaching to the delivery wire. The device is shipped attached to a 155-cm delivery wire in a hoop dispenser.

What are the restrictions after a PFO closure?

After 5 days, no heavy activity that causes deep/heavy breathing for 6-8 weeks. No driving for 5 days. No tub baths, swimming, or hot tubs for 7 days. Most patients return to work within one week.

Can a PFO cause shortness of breath?

Unless there are other defects, there are no complications from a PFO in most cases. Some people may have a condition shortness of breath and low arterial blood oxygen levels when sitting or standing. This is called platypnea-orthodeoxia. This is rare.

What is Amplatzer AvP 2?

Amplatzer™ Vascular Plug II (AVP II) Multi-layered mesh designed to increase density and flow disturbance7 Six planes of cross sectional coverage7resulting in rapid occlusion¹ Select a device that is ~30-50% larger in diameter than the target vessel diameter7 Amplatzer™ Vascular Plug 4 (AVP 4)

Is the Amplatzer™ vascular plug 4 device safe?

The AMPLATZER™ Vascular Plug 4 device consists of a nickel-titanium alloy, which is generally considered safe. However, in vitro testing has demonstrated that nickel is released from this device for a minimum of 60 days.

What does AVP 4 stand for?

Amplatzer™ Vascular Plug 4 (AVP 4) 1 Simple delivery through an 0.038” guide wire compatible diagnostic catheter 8 2 Easy tracking through tortuous anatomy 6 3 Extended reach to distal vasculature 6 4 Select a device that is ~30-50% larger in diameter than the target vessel diameter 8 More

Will the Amplatzer™ vascular plug migrate in an MR environment?

The AMPLATZER™ Vascular Plug should not migrate in this MR environment. Non-clinical testing has not been performed to rule out the possibility of migration at field strengths higher than 3.0 Tesla. In this testing, the device produced a temperature rise of 1.1°C at 1.5 Tesla and 1.6°C at 5.0 Tesla.

What is a Amplatzer vascular plug?

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.

Is Amplatzer vascular plug MRI safe?

Patients with PAVMs who have undergone embolization using stainless steel coils and/or Amplatzer vascular plugs can safely undergo 1.5 T MRI which should not be delayed in emergency situations.

What is Amplatzer vascular plug made of?

The Amplatzer Vascular Plug (AVP) is a cylindrical plug made of self-expanding nitinol wire mesh with precise delivery control, which can be used for a variety of vascular pathologies.

Does the type and size of Amplatzer vascular plug affect the occlusion time of pulmonary arteriovenous malformations?

CONCLUSION. The use of AVP 2, and increase in device oversizing were not associated with reduction in the OT of PAVMs. There was no reported difference in safety between the two devices, and no major complications were noted.

What is vascular plugging?

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 long does PFO closure take?

What happens during PFO closure? The PFO closure procedure is relatively painless and does not require any surgical incisions. The procedure takes between 30 minutes and two hours.

What are vascular plugs used for?

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.

Is Amplatzer device safe?

Closure of atrial septal defect with the AMPLATZER Septal Occluder is safe and effective. The rate of hemodynamic compromise and cardiac erosion is rare. The risk factors for cardiac erosion after device closure are not yet clear.

Is the Amplatzer vascular Plug 2 FDA approved?

The Plug 2 is availbale in sizes from 3 to 22mm, with the larger sizes requiring a 7F sheath The Amplatzer Vascular Plug II is CE marked and FDA approved. PubMed literature on the PLug to can be found here. “This device provides easy, fast vessel occlusion replacing the use of multiple coils, and it is an invaluable device in emergency situations.”

What is Amplatzer AvP 2?
