A device consisting of a wire for occluding an aperture within a body surface, such as atrial and ventricular septal defects (and the method of using such a device). The wire comprises two configurations, an elongated configuration for passage into said body through a catheter and through the aperture, and a preprogrammed configuration including occlusion-forming wire segments, one on each side of said aperture. The wire also includes means (preferably a temperature-induced shape change) for changing the wire from the elongated configuration to the preprogrammed configuration in the body.
