Abstract
Abstract Disclosed is a closure catheter, for closing a body cavity such as a vessel, or the left atrial appendage 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 close the body cavity. Methods are also disclosed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
89 words
A method of reducing the volume of the left atrial appendage, 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 through the heart and into the left atrial appendage; inclining the anchors radially outwardly from the axis of the catheter towards tissue surrounding the opening to the left atrial appendage; deploying the anchors from the catheter and into the tissue; and retracting the sutures to reduce the volume of the left atrial appendage.
Claim 2
Independent Claim
89 words
A method of reducing the volume of the left atrial appendage, 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 through the heart and into the left atrial appendage; inclining the anchors radially outwardly from the axis of the catheter towards tissue surrounding the opening to the left atrial appendage; deploying the anchors from the catheter and into the tissue; and retracting the sutures to reduce the volume of the left atrial appendage.
Claim 3
Dependent Claim
24 words
A method as in claim 1 , wherein the inclining step comprises proximally retracting a control for inclining anchor supports which carry the anchors.
Claim 4
Dependent Claim
17 words
A method as in claim 2 , wherein proximally retracting the control axially compresses the anchor support.
Claim 5
Dependent Claim
24 words
A method as in claim 1 , wherein the deploying the anchors step comprises proximally retracting a deployment line removably connected to each anchor.
