Abstract
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.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
110 words
A septal defect closure device comprising a first occluding disk having a first flexible membrane attached to a first frame and a second occluding disk having a second flexible membrane attached to a separate second frame; the first frame having at least two outwardly extending loops joined to one another by flexible joints, the loops being 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 being attached to the central portion of the second membrane to define a conjoint disk, the flexible joints of the first frame being received within the conjoint disk.
Claim 2
Dependent Claim
110 words
A septal defect closure device comprising a first occluding disk having a first flexible membrane attached to a first frame and a second occluding disk having a second flexible membrane attached to a separate second frame; the first frame having at least two outwardly extending loops joined to one another by flexible joints, the loops being 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 being attached to the central portion of the second membrane to define a conjoint disk, the flexible joints of the first frame being received within the conjoint disk.
Claim 3
Dependent Claim
24 words
The septal defect closure device of claim 1 wherein the flexible joints are received between the first and second membranes within the conjoint disk.
Claim 4
Dependent Claim
40 words
The septal defect closure device of claim 1 wherein the first membrane is attached to the second membrane via stitching, at least one stitch covering a portion of the first frame to retain the flexible joint within the conjoint disk.
Claim 5
Dependent Claim
25 words
The septal defect closure device of claim 3 wherein at least one stitch passes through an orifice in at least one of the flexible joints.
Claim 6
Dependent Claim
26 words
The septal defect closure device of claim 1 wherein at least one of the flexible joints is stitched to the first membrane within the conjoint disk.
Claim 7
Dependent Claim
28 words
The septal defect closure device of claim 1 wherein at least one of the flexible joints is stitched to the first and second membranes within the conjoint disk.
Claim 8
Dependent Claim
26 words

Claim 9
Dependent Claim
135 words
A septal defect closure device comprising first and second occluding disks, each disk comprising a flexible, biologically compatible membrane and a frame for elastically deploying the membrane; a central portion of the membrane of the first disk being joined to a central portion of the membrane of the second disk to define a flexible joining segment having a collapsible periphery; the frame of the first disk and the frame of the second disk each being formed from separate length of resilient wire; the frame of the first disk in a deployed configuration defining at least two petals joined to each other via at least two flexible joints, the petals extending outwardly from the joining segment to elastically deploy the membrane attached thereto and the flexible joints being positioned within the periphery of the joining segment.
Claim 10
Dependent Claim
135 words
A septal defect closure device comprising first and second occluding disks, each disk comprising a flexible, biologically compatible membrane and a frame for elastically deploying the membrane; a central portion of the membrane of the first disk being joined to a central portion of the membrane of the second disk to define a flexible joining segment having a collapsible periphery; the frame of the first disk and the frame of the second disk each being formed from separate length of resilient wire; the frame of the first disk in a deployed configuration defining at least two petals joined to each other via at least two flexible joints, the petals extending outwardly from the joining segment to elastically deploy the membrane attached thereto and the flexible joints being positioned within the periphery of the joining segment.
Claim 11
Dependent Claim
26 words

The septal defect closure device of claim 8 wherein the joining segment comprises a conjoint disk formed by attaching the first membrane directly to the second membrane, the flexible joints of the frame of the first disk being held between the first and second membranes of the conjoint disk.
Claim 13
Dependent Claim
110 words
A septal defect closure device comprising a first occluding disk having a first flexible membrane attached to a first frame and a second occluding disk having a second flexible membrane attached to a separate second frame; a central portion of the first membrane being joined to the central portion of the second membrane to define a flexible joining segment having a collapsible periphery; the first frame being attached to the first membrane such that in its deployed configuration it will define at least two petals of taut fabric joined to each other by at least two flexible joints, the flexible joints being positioned within the periphery of the joining segment.
Claim 14
Dependent Claim
110 words
A septal defect closure device comprising a first occluding disk having a first flexible membrane attached to a first frame and a second occluding disk having a second flexible membrane attached to a separate second frame; a central portion of the first membrane being joined to the central portion of the second membrane to define a flexible joining segment having a collapsible periphery; the first frame being attached to the first membrane such that in its deployed configuration it will define at least two petals of taut fabric joined to each other by at least two flexible joints, the flexible joints being positioned within the periphery of the joining segment.
Claim 15
Dependent Claim
