CRYOADHESIVE DEVICE FOR LEFT ATRIAL APPENDAGE OCCLUSION

摘要

An epicardial device, system, and method for stabilizing the left atrial appendage during a left atrial appendage ligation/occlusion procedure. A cryoadhesion device including a stabilization element is positioned within the pericardial space proximate the left atrial appendage through subxiphoid access. Once the stabilization element is in contact with the left atrial appendage, the stabilization element is cooled to a temperature that is sufficient to cryoadhere the stabilization element to the left atrial appendage. In this way, the cryoadhesion device stabilizes the left atrial appendage in order to perform left atrial appendage ligation/occlusion with a secondary medical device.
