First Claim
Patent Images
1. A method of implanting a device in the left atrial appendage, comprising the steps of:
- providing a deployment catheter, having an elongate flexible body with a proximal end and a distal end, a control on the proximal end and a device removably carried adjacent the distal end;
positioning at least a portion of the device in the left atrial appendage; and
manipulating the control to enlarge the device under positive force;
wherein the device comprises an expandable frame comprising at least two spokes, wherein the spokes are cut from a tube.
