Abstract

This disclosure is directed to an aperture occlusion device and a method for occluding an aperture, including a perimembranous ventricular septal defect. The aperture occlusion device includes a wire frame element. The wire frame forms geometric shapes that include an occluder region and a securing region. The occluder region and the securing region are separated by an attachment region including a waist. The occluder region and securing region can include membranous coverings. The device can be attached to a delivery hub. The wires forming the occluder region and securing region can have a shape-memory capability such that they can be collapsed and distorted in a sheath during delivery, but resume and maintain their intended shape after delivery.
