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.

A device for deploying at least one tissue anchor, comprising:
- a closure catheter having a proximal end and a distal end;
- and
- at least one tissue anchor positioned in an anchor supporting portion of the closure catheter and configured to be released from the anchor supporting portion;
- wherein the anchor supporting portion is moveable between an axial orientation and an inclined orientation, wherein the at least one tissue anchor is deployable from the anchor supporting portion when said portion is in its inclined orientation.

A device for deploying a patch for covering a tissue opening comprising:
- a catheter having a proximal end and a distal end;
- a plurality of tissue anchors positioned in the distal end of the catheter and configured to be released from the distal end circumferentially about the opening;
- and
- a patch configured to be attached across the opening by the plurality of tissue anchors;
- wherein the catheter is configured to advance the anchors radially outward from the catheter, through the patch, and into tissue surrounding the tissue opening.
