A self-centering umbrella-type septal closure device which includes a proximal and distal occluder each having a plurality of arms supporting the occlusion shells. Each of the proximal and distal support arms have at least three coils any one or more of which is secured by a centering mechanism so as to control the positioning of the closure device so that it is centered about a defect.
