1. An epicardial method of stabilizing a left atrial appendage of a heart, the method comprising:
positioning a guide sheath within a pericardial space proximate the left atrial appendage,
positioning a stabilization element of a cryoadhesion device within the guide sheath, the stabilization element including:
a distal end defining a cross-sectional shape having a thermally insulated side not for cryoadhesion and a non-insulated side for cryoadhesion, and
a non-expandable thermally transmissive region located on the non-insulated side of the cross-sectional shape; and
positioning a secondary device within the guide sheath adjacent the thermally insulated side of stabilization element, the secondary device including an elongate body that is partially surrounded by the thermally insulated side of the stabilization element; and
advancing the stabilization element from the guide sheath; and
cooling the stabilization element to a temperature that is sufficient to cause cryoadhesion between the non-insulated side of the stabilization element and the left atrial appendage; and
occluding the left atrial appendage with the secondary device.
