An epicardial device, system, and method for stabilizing the left atrialappendage during a left atrial appendage ligation/occlusion procedure. Acryoadhesion device including a stabilization element is positioned within thepericardial space proximate the left atrial appendage through subxiphoidaccessOnce the stabilization element is in contact with the left atrial appendage,thestabilization element is cooled to a temperature that is sufficient tocryoadherethe stabilization element to the left atrial appendage In this way, thecryoadhesion device stabilizes the left atrial appendage in order to performleftatrial appendage ligation/occlusion with a secondary medical device.
