Amplatzer Duct Occluder device: a new technology for the closure of the moderate-to-large-sized patent ductus arteriosus.

The Amplatzer Duct Occluder is a novel device designed to allow for the transcatheter closure of virtually all sized patent ductus arteriosuses. Prior technologies have been cumbersome and challenging to deploy with somewhat less than ideal closure rates associated with their use. This article summarizes the present knowledge about the Amplatzer Duct Occluder device and its various indications. With the introduction of this device as well as the use of embolization coils, all but the neonatal patent ductus arteriosuses can now be safely, consistently and successfully closed in the cardiac catheterization laboratory.
