Devices and methods for closing a left atrial appendage

A method for closing a left atrial appendage, the method comprising:

• anchoring an expandable disk to an everted tissue wall of the left atrial appendage with a deployment anchor attached to the expandable disk;
• expanding the expandable disk to expand the everted tissue wall to cover an ostium of the left atrial appendage;
• and
• securing the everted tissue wall of the left atrial appendage to a wall of the left atrium with a plurality of closure anchors.

A device for closing a left atrial appendage, the device comprising:

• an expandable disk having an expanded diameter that is larger than 10 mm;
• a deployment anchor attached to the expandable disk near a center of a first side of the expandable disk, the deployment anchor configured to puncture a tissue of a left atrial appendage and to anchor the expandable disk to the tissue of the left atrial appendage;
• a securing ring forming an annulus;
• and
• a plurality of closure anchors attached to the securing ring, the plurality of closure anchors configured to secure the expandable disk to tissue of a left atrium,
• wherein the expandable disk is configured for delivery in a compact state and expands to an expanded state to cause an everted left atrial appendage to assume a size that is larger than an ostium of the left atrial appendage.
