ABSTRACT:
The star occluder includes a frame formed from a first plurality of arms extending radially in a first plane and a second plurality of arms extending radially in a second plane which is spaced from and substantially parallel to the first plane. Loop joinder legs extend between the base ends of the first and second arms, and a first membrane sheet is supported by and extends over the first plurality of arms while a second membrane sheet is supported by and extends over the second group of arms. The frame is somewhat flexible when expanded so that the loop joinder legs expand into contact with the periphery of a septal defect and determine the size to which the frame will expand.
