Amplatz Canine Ductal Occluder
The Amplatz Canine Duct Occluder is a self-expanding device made from a nitinol wire mesh and is used to close patent ductus arteriosus (PDA) in dogs. A distal flat disk on the pulmonary artery side of the ductal ostium provides secure positioning in the pulmonary artery. As the device is implanted, the proximal cupped disk expands to conform to the shape of the ductal ampulla. The waist of the device spans the pulmonic ostium of the ductus and the dense nitinol mesh occludes the communication. With thousands of successful implantations, the Amplatz Canine Ductal Occluder is now the standard of care for the closure of canine patent ductus arteriousus.
