Abstract
Abstract Disclosed is a closure catheter, and methods for reducing the volume of a body cavity such as a vessel, or a portion of the heart. The closure catheter includes a plurality of deployable tissue anchors, which may be laterally deployed into surrounding tissue. The anchors may thereafter be used to draw the tissue radially inwardly, to reduce the volume of the body cavity. Methods are also disclosed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
110 words
1 . A method of securing a plurality of tissue anchors about the circumference of a hollow organ to reduce the volume of the organ, comprising the steps of: providing a tissue anchor delivery catheter having a plurality of anchor supports moveable between an axial orientation and an inclined orientation, and an anchor carried by each anchor support, each anchor having a suture secured thereto; transluminally advancing the catheter to a target site within a hollow organ while the anchor supports are in the axial orientation; advancing the anchor supports from the axial orientation to the inclined orientation; and deploying the anchors from the anchor supports and into the tissue.
Claim 2
Dependent Claim
110 words
1 . A method of securing a plurality of tissue anchors about the circumference of a hollow organ to reduce the volume of the organ, comprising the steps of: providing a tissue anchor delivery catheter having a plurality of anchor supports moveable between an axial orientation and an inclined orientation, and an anchor carried by each anchor support, each anchor having a suture secured thereto; transluminally advancing the catheter to a target site within a hollow organ while the anchor supports are in the axial orientation; advancing the anchor supports from the axial orientation to the inclined orientation; and deploying the anchors from the anchor supports and into the tissue.
Claim 3
Dependent Claim
24 words
2 . A method as in claim 1 , wherein the advancing the anchor supports step comprises proximally retracting a control on the catheter.
Claim 4
Dependent Claim
35 words
3 . A method as in claim 1 , further comprising the step of proximally retracting a suture to draw the anchors radially inwardly toward each other to reduce the volume of the hollow organ.
Claim 5
Dependent Claim
16 words
4 . A method as in claim 3 , wherein the hollow organ comprises the heart.
Claim 6
Dependent Claim
31 words
5 . A method as in claim 1 , wherein the deploying step comprises proximally retracing a deployment wire associated with each tissue anchor to advance the anchor into the tissue.
Claim 7
Dependent Claim
83 words
6 . A method of reducing the volume of a portion of the heart, comprising the steps of: providing a catheter having at least four tissue anchors thereon, the anchors each having a suture secured thereto; advancing the catheter into a portion of the heart; inclining the anchors radially outwardly from the axis of the catheter towards surrounding tissue; deploying the anchors from the catheter and into the tissue; and retracting the sutures to reduce the volume of the portion of the heart.
Claim 8
Dependent Claim
83 words
6 . A method of reducing the volume of a portion of the heart, comprising the steps of: providing a catheter having at least four tissue anchors thereon, the anchors each having a suture secured thereto; advancing the catheter into a portion of the heart; inclining the anchors radially outwardly from the axis of the catheter towards surrounding tissue; deploying the anchors from the catheter and into the tissue; and retracting the sutures to reduce the volume of the portion of the heart.
Claim 9
Dependent Claim
26 words
7 . A method as in claim 6 , wherein the inclining step comprises proximally retracting a control for inclining anchor supports which carry the anchors.
Claim 10
Dependent Claim
19 words
8 . A method as in claim 7 , wherein proximally retracting the control axially compresses the anchor support.
Claim 11
Dependent Claim
26 words
9 . A method as in claim 6 , wherein the deploying the anchors step comprises proximally retracting a deployment line removably connected to an anchor.
Claim 12
Dependent Claim
31 words
10 . A method as in claim 6 , wherein the retracting the sutures to reduce the volume of the portion of the heart comprises reducing the volume of a ventricle.
Claim 13
Dependent Claim
33 words
11 . A method as in claim 6 , wherein the retracting the sutures to reduce the volume of the portion of the heart comprises reducing the volume of the left atrial appendage.
