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: 7
Claim 1
Independent Claim
93 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; 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
