Abstract:
1. A method of preventing passage of embolic material from a left atrial appendage of a patient, comprising: providing a deployment catheter having an elongate flexible body with a proximal end and a distal end, and an implantable device removably carried by the distal end, said device comprising an impervious barrier, said device radially expandable from a reduced diameter to an enlarged diameter and configured to conform to an inside surface of the left atrial appendage; positioning at least a portion of the device by passing the device into the ostium of the left atrial appendage in the left atrial appendage; and enlarging the device within the left atrial appendage, wherein said impervious barrier extends across the left atrial appendage when enlarged so that the device circumferentially seals against the inside surface of the left atrial appendage.
