Abstract

The daisy occluder (10) includes a frame (12) formed from a first plurality of arms (14) extending radially in a first plane and a second plurality of arms (16) extending radially in a second plane which is spaced from and substantially parallel to the first plane. Loop joinder links (22) extend between the base ends (20, 18) of the first and second arms, and a first membrane sheet (28) is supported by and extends over the first plurality of arms (14) while a second membrane sheet (30) is supported by and extends over the second group of arms (16). The frame (12) is somewhat flexible when expanded so that the loop joinder links (20) expand into contact with the periphery of a septal defect and determine the size to which the frame (12) will expand.
