1. A septal defect occluder comprising:
- a frame adapted to be inwardly radially collapsed from an expanded configuration to a collapsed configuration,said frame in the expanded configuration including a first plurality of spaced, loop shaped arms extending radially in a first plane, said first arms each having a base end formed by two spaced end portions,a second plurality of spaced, loop shaped arms extending radially in a second plane substantially parallel to and spaced from said first plane, said second arms each having a base end formed by two spaced end portions,and a plurality of spaced loop joinder links extending between the base ends of said first and second arms, an end portion of each of said first arms being connected by one of said plurality of loop joinder links to an end portion of a second arm,a first sheet of material supported by and extending over said first arms, anda second sheet of material supported by and extending over said second arms.

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.

22. A septal defect occluder comprising:
-
a frame adapted to be inwardly radially collapsed from an expanded configuration to a collapsed configuration, said frame in the expanded configuration including a first plurality of spaced arms extending radially in a first plane, each of said first arms having a base end and an outermost end section spaced from said base end, a second plurality of spaced arms extending radially in a second plane substantially parallel to and spaced from said first plane, each of said second arms having a base end and an outermost end section spaced from said base end, the outermost end sections of said first arms being curved toward said second arms and the outermost end sections of said second arms being curved toward said arms when said frame is in the expanded configuration, and loop joinder links extending between the base ends of said first and second arms, a first sheet of material supported by and extending over said first arms, and a second sheet of material supported by and extending over said second arms, said first sheet of material being provided with pockets to receive the outermost end sections of said first arms and said second sheet of material being provided with pockets to receive the outermost end sections of said second arms. - View Dependent Claims (23, 24, 25, 26, 27, 28)
