Figure 2: Transvenous closure of a Type A patent ductus arteriosus (a), angiogram in straight lateral view. The device is advanced through the duct to the descending aorta under fluoroscopic control. All loops located distal to the device waist are deployed within the aorta and the whole delivery system is retracted into the ductal ampulla (b). The implantation catheter is simultaneously retracted, while the delivery system is pushed forward slightly to deploy the remaining coil windings anchoring the pulmonary end of the duct (c)
