Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
158 words
A device (10) for percutaneous transluminal repair
of septal defects comprising: a first occluder (12) and a second occluder (14)
each having a collapsed cross sectional configuration
smaller than that of a defect to be repaired and an
expanded configuration larger than that of the defect;
and a connector (16) for fastening said first occluder
to said second occluder, wherein said
device is insertable into a patient when said first and
second occluders are connected by said connector; characterised in
that said connector allows rotational motion of said
first occluder relative to said second occluder when
said occluders are in their expanded configurations, in
that at least one of said first occluder (12) or said
second occluder (14) comprises a central hub (16) having
a plurality of elongated struts (18) radiating
therefrom, and in that at least one of said elongated
struts (18) includes a flexural hinge point (22) at a
location remote from said central hub (16).
Claim 2
Dependent Claim
18 words
The device of claim 1 wherein at least one of said
elongated struts (18) comprises a radiopaque material.
Claim 3
Dependent Claim
24 words
The device of claim 1 wherein at least one of said
elongated struts (18) includes a radiopaque material on
at least one surface thereof.
Claim 4
Dependent Claim
14 words
The device of claim 1 wherein said connector
comprises a linked loop assembly (82,84,86).
Claim 5
Dependent Claim
15 words
The device of claim 1 wherein said connector
comprises a ball and collar assembly (54,58,62,72).
Claim 6
Dependent Claim

The device of claim 1 wherein said connector
includes at least one pivot location (62).
Claim 7
Dependent Claim
25 words
The device of claim 3 wherein each occluder
includes at least one elongated strut (18) having a
radiopaque material on at least one surface thereof.
Claim 8
Dependent Claim
26 words
The device of claim 7 wherein the radiopaque
material on said first occluder (12) is fluoroscopically
distinguishable from the radiopaque material on said
second occluder (14).
Claim 9
Dependent Claim
27 words
The device of claim 1 wherein at least one of said
elongated struts (18) includes a flexural hinge point
(20) located adjacent to said central hub (16).
Claim 10
Dependent Claim
22 words
The device of claim 1 wherein at least one of said
elongated struts (18) includes a loop (24) at its distal
end.
Claim 11
Dependent Claim
