Abstract
A device, system, and method for ligating the left atrial appendage without creating pro-arrhythmic tissue. The device may generally include a snare including a thermally transmissive distal portion and a suture including a distal portion, both distal portions having a lasso-shaped configuration that may be positioned proximate the base of the left atrial appendage. Once the distal portions of the snare and the suture are tightened around the base of the left atrial appendage, the thermally transmissive distal portion of the snare may be activated to create an ablation lesion in adjacent left atrial appendage tissue. The lesion may be created with radiofrequency energy or through cryoablation by the circulation of refrigerant within the thermally transmissive distal portion of the snare.
