Claim:
1. A device, to treat at least one of a vascular and septal opening, comprising biocompatible components, wherein: the components comprise a structure having two opposing wings, a distal wing and a proximal wing, coupled to each other by an axis that is covered by a covering comprising a shape memory polymer foam, the wings, when expanded, are configured to be: generally planar with a surface in which the opening is to be disposed, and larger in surface area than a diameter of the opening, and the distal wing, when expanded, is configured to be collapsible into a secondary shape that together with the other components of the device may be disposed inside a vascular catheter, the wings comprise neat, unfoamed, shape memory polymer, the device is configured to be secured in the opening by longitudinal shrinkage, along a long axis of the axis, of an additional shape memory polymer included in the axis, the additional shape memory polymer is different from, but coupled to, the covering that comprises the shape memory polymer foam, and the shape memory polymer foam is located on the additional shape memory polymer.
