ABSTRACT:
The present invention provides a septal defect closure device (10) having a first occluding disk (30) having a first flexible membrane (32) attached to a first frame (34) and a second occluding disk (20) having a second flexible membrane (22) attached to a separate second frame (24). The first frame has at least two outwardly extending loops joined to one another by flexible joints. These loops are attached to the first membrane to define taut fabric petals when the first disk is in a deployed configuration. A central portion of the first membrane is joined to the central portion of the second membrane via a joining segment, which may comprise a conjoint disk. The flexible joints of the first frame are received within the joining segment. This septal defect closure device provides enhanced retrievability.
