Answer

More recently, the Amplatzer device has expanded the ability to close patent ductus arteriosus (PDA) at cardiac catheterization. This device is more reliable and easier to implant in a large patent ductus arteriosus (PDA) than spring occluding coils. The major disadvantage of the design is that the aortic part of the device can protrude into the descending aorta and partly obstruct the lumen, especially in infants. However, the Amplatzer duct occluder II (ADO II), a nitinol flexible mesh with a symmetrical design to provide high conformability, has been approved in Europe for treatment of all types of patent ductus arteriosus (PDA).
