Abstract
A septal defect occluder is provided having first and second occluder panels. Each occluder panel includes a fabric support structure and fabric suspended therefrom. The occluder panels are conjoined at a plurality of discrete points which are located within an area bounded by each perimeter of the fabric support structures, as well as on the fabric, to thereby form a defect conforming region for the occluder. In an alternate embodiment, each occluder panel includes a cambered fabric support structure and fabric suspended from a perimeter thereof, the occluder panels being arranged in cooperative cambered opposition such that the perimeters of the cambered fabric support structures impart a clamping force upon tissue adjacent a tissue defect interposed there between when the occluder is deployed for tissue defect occlusion.
