Abstract
Abstract A transcatheter occluder device for closing an opening in a tissue wall includes a body member formed of an open cell polymer foam capable of holding a predetermined occluder shape and being resiliently compressible for transcatheter deployment. The occluder device includes a pair of spaced-apart disks interconnected by a narrow neck portion. Grip means are provided in the neck portion to releasably engage a guide wire for deployment of the occluder device through a catheter.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
84 words
A transcatheter occluder device for closing an opening in a tissue wall or a vessel wall, the device comprising: a body member formed substantially from an open cell polymer foam material which is self-supporting to hold a predetermined occluder shape and is resiliently compressible for transcatheter deployment; the material being a biologically compatible material or coated with a biologically compatible material; the body member having means for closing the opening; and the body member having means for retaining the body member in the opening.
Claim 2
Dependent Claim
84 words
A transcatheter occluder device for closing an opening in a tissue wall or a vessel wall, the device comprising: a body member formed substantially from an open cell polymer foam material which is self-supporting to hold a predetermined occluder shape and is resiliently compressible for transcatheter deployment; the material being a biologically compatible material or coated with a biologically compatible material; the body member having means for closing the opening; and the body member having means for retaining the body member in the opening.
Claim 3
Dependent Claim
23 words
The device as claimed in claim 1 further comprising means for engaging a side edge of the opening for centering the body member.
Claim 4
Dependent Claim
28 words
The device as claimed in claim 1 wherein at least a portion of a periphery of the body member is engagable with a side edge of the opening.
Claim 5
Dependent Claim
29 words
The device as claimed in claim 1 wherein the body member has a cross-sectional area that is at least the same size as a cross-sectional area of the opening.
Claim 6
Dependent Claim
21 words
The device as claimed in claim 1 wherein the body member is shaped to correspond to the shape of the opening.
Claim 7
Dependent Claim
15 words
The device as claimed in claim 1 wherein the body member has a cylindrical shape.
Claim 8
Dependent Claim
37 words
The device as claimed in claim 1 wherein the body member comprises a number of outwardly projecting ribs on a surface of the body member, said ribs being engagable with an edge of the opening in use.
Claim 9
Dependent Claim
36 words
The device as claimed in claim 1, wherein the retaining means comprises a pair of disks each of larger size than the opening, one of said disks being mounted at each end of the body member.
Claim 10
Dependent Claim
27 words
The device as claimed in claim 1, wherein the retaining means comprises a plurality of retaining fingers extending laterally outwardly at each end of the body member.
Claim 11
Dependent Claim
22 words
The device as claimed in claim 1 wherein the device further comprises radiopaque means to facilitate viewing of the device during deployment.
Claim 12
Dependent Claim
30 words
The device as claimed in claim 1 wherein the body member further comprises grip means engagable with a guide wire for movement of the device through a catheter for deployment.
Claim 13
Dependent Claim
96 words
The device as claimed in claim 1, further comprising a tubular sleeve mounted on the body member, the sleeve having a bore and being adapted to engage a clamp on a guide wire to facilitate movement of the device through a catheter for deployment, said clamp comprising a split collar through which the guide wire passes and an enlarged head at an outer end of the guide wire which is moveable through the collar to expand the collar within the bore of the sleeve to releasably clamp the collar within the sleeve of the body member.
Claim 14
Dependent Claim
43 words
The device as claimed in claim 1, further comprising a lug mounted on the body member which is adapted to releasably engage a collet at a distal end of a guide wire to facilitate movement of the device through a catheter for deployment.
