Abstract
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.

Claim 5
Dependent Claim
91 words
A tissue defect occluder comprising first and second occluder panels, each occluder panel including a cambered fabric support structure and fabric suspended from a perimeter of said cambered fabric support structure, said occluder panels being arranged in cooperative cambered opposition such that the perimeters of said cambered fabric support structures impart a clamping force upon tissue adjacent a tissue defect interposed there between when said occluder is deployed for tissue defect occlusion wherein said occluder panels are conjoined at a plurality of discrete points to thereby form a defect conforming region.
Claim 6
Dependent Claim
91 words
A tissue defect occluder comprising first and second occluder panels, each occluder panel including a cambered fabric support structure and fabric suspended from a perimeter of said cambered fabric support structure, said occluder panels being arranged in cooperative cambered opposition such that the perimeters of said cambered fabric support structures impart a clamping force upon tissue adjacent a tissue defect interposed there between when said occluder is deployed for tissue defect occlusion wherein said occluder panels are conjoined at a plurality of discrete points to thereby form a defect conforming region.
Claim 7
Dependent Claim
26 words
The occluder of claim 4 wherein said discrete conjoined points are located within each of the cambered fabric support structures, as well as on said fabric.
Claim 8
Dependent Claim
16 words
The occluder of claim 5 wherein said cambered fabric support structure includes perimeter and traversing segments.
Claim 9
Dependent Claim
38 words
The occluder of claim 6 wherein the conjoined points within the cambered fabric support structure comprise loops formed in the traversing segments of each of the cambered fabric support structures, thereby defining internal eyelets for said support structures.
