Abbott offers two devices for percutaneous transcatheter ASD closure.
The Amplatzer Septal Occluder, CE Marked since 1998, is intended for patients with an ASD in the secundum position or patients who have undergone a fenestrated Fontan procedure and who now require closure of the fenestration.
The Amplatzer Septal Occluder has a wide connecting waist that centers the device and fills the ASD. This occluder—offering the widest range of ASD sizes—can treat defects from 3 mm to 38 mm.
The Amplatzer Cribriform Multifenestrated Septal Occluder is safe and effective for the closure of multifenestrated (cribriform) ASDs.1
Multiple, or fenestrated, ASDs that require closure are not uncommon; in fact nearly 10% of patients with secundum-type ASD are found to have multifenestrated ASDs.1
In many ways similar to the Amplatzer Septal Occluder, the Amplatzer Cribriform Occluder consists of 2 uniformly sized discs with a very small connecting waist. The waist allows the device to cover a much larger fenestrated area of the atrial septum. This occluder’s disc diameters range from 18 to 40 mm.
The Amplatzer Cribriform Occluder is effective in treating a multiple-fenestrated atrial septum.
Both types of Amplatzer Septal Occluders offer these unique features:
- Discs that are designed to securely appose the septal wall on each side of the defect
- Polyester material that promotes occlusion and tissue in-growth
- Ability to be recaptured and redeployed to ensure precise device placement
