AbstractAn intravascular prostheses is delivered transarterially or transvenously to occlude cardiac defects. The defects, which may include the patent ductus arteriosus, the ventricular septal defect and the atrial septal defect. The prostheses is a device having a distal occluder attached to a string and a proximal occluder connected to the string. The occluders are delivered to the heart by known methods. With the distal occluder on the distal side of the defect and the proximal occluder on the proximal side of the defect the occluders are adjusted according to the thickness of the heart structure at the defect. In one embodiment the adjustment is by moving the distal occluder over a series of knots or buttons in the string. In another embodiment the proximal occluder is connected to the distal occluder by an elastic string so that the elastic tension of the strings bring the occluders into position. A radiopaque button is placed upon the string to aid positioning the occluders.
