Abstract
Abstract A catheter delivered device to close a septal defect, the device comprising a cylindrical shaft of metal or polymeric material with concentric parallel cuts through the wall of the device which create flattened support struts. The center of the support struts move radially away from the axis in a hinge like fashion in response to the movement of the device's proximal and distal ends toward the center of the device. This movement is reversibly effected through mechanical means. The device can be coated with growth factors, mitogenic factors or other determinants which can improve tissue growth such that tissue ingrowth can occur over a period of time. The catheter itself may be an ultrasonic imaging catheter.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
Apparatus for closing an intravascular defect within the body, including septal defects, comprising: a closure device constructed and arranged to have a percutaneous delivery configuration and an aperture closing configuration, the device being further constructed and arranged to be reversibly operable between the two configurations such that the device may be changed from an aperture closing configuration back to a delivery configuration for removal or repositioning said closure device further being constructed and arranged to be deployed through a delivery catheter; a delivery catheter for delivering the closure device, when in the delivery configuration, percutaneously to the body site of an intravascular defect to be closed, and intralumen mechanical mechanism means associated with the catheter and closure device for remotely operating the device in situ between the two configurations.
Claim 2
Dependent Claim
129 words
Apparatus for closing an intravascular defect within the body, including septal defects, comprising: a closure device constructed and arranged to have a percutaneous delivery configuration and an aperture closing configuration, the device being further constructed and arranged to be reversibly operable between the two configurations such that the device may be changed from an aperture closing configuration back to a delivery configuration for removal or repositioning said closure device further being constructed and arranged to be deployed through a delivery catheter; a delivery catheter for delivering the closure device, when in the delivery configuration, percutaneously to the body site of an intravascular defect to be closed, and intralumen mechanical mechanism means associated with the catheter and closure device for remotely operating the device in situ between the two configurations.
Claim 3
Dependent Claim
15 words
The apparatus of claim 1 wherein the closure device is deformable between the two configurations.
Claim 4
Dependent Claim
14 words
The apparatus of claim 1 wherein the closure device is comprised of polymeric material.
Claim 5
Dependent Claim
13 words
The apparatus of claim 1 wherein the device is comprised of metallic material.
Claim 6
Dependent Claim
12 words
The apparatus of claim 1 wherein the device includes a polymeric coating.
Claim 7
Dependent Claim
162 words
Apparatus for closing an intravascular defect within the body, including septal defects, comprising: a closure device constructed and arranged to have a percutaneous delivery configuration and an aperture closing configuration, the device being further constructed and arranged to be reversibly operable between the two configurations, said closure device being generally cylindrical when in said percutaneous delivery configuration, said closure device is of a unitary construction and having a central portion separating a proximal and a distal portion, said distal and proximal portions being deformable to expand in radial diameter while decreasing in length to achieve an aperture closing configuration, said closure device further being constructed and arranged to be deployed through a delivery catheter; a delivery catheter for delivering the closure device, when in the delivery configuration, percutaneously to the body site of an intravascular defect to be closed, and intralumen mechanical mechanism means associated with the catheter and closure device for remotely operating the device in situ between the two configurations.
Claim 8
Dependent Claim
162 words

Claim 9
Dependent Claim
122 words
Apparatus for closing an intravascular defect within the body, including septal defects, comprising: a closure device constructed and arranged to have a percutaneous delivery configuration and an aperture closing configuration, the device being further constructed and arranged to be reversibly operable between the two configurations in order to allow repositioning of said closure device after a first trial placement, said closure device further being constructed and arranged to be deployed through a delivery catheter; a delivery catheter for delivering the closure device, when in the delivery configuration, percutaneously to the body site of an intravascular defect to be closed, and intralumen mechanical mechanism means associated with the catheter and closure device for remotely operating the device in situ between the two configurations.
Claim 10
Dependent Claim
