LEFT ATRIAL APPENDAGE MANIPULATION AND TRACTION

Abstract:

A method of positioning an occlusion clip proximate a left atrial appendage may include creating an access port that exposes the left atrial appendage; delivering a suction grasper via the access port, the suction grasper including opposing jaws each having a suction port; delivering an occlusion clip via the access port; grasping the left atrial appendage via the suction grasper by applying suction to an exterior of the left atrial appendage so that a portion of the left atrial appendage interposes the opposing jaws while suction is applied via the suction ports; repositioning the suction grasper to tension the left atrial appendage; delivering an occlusion clip via the access port; clamping a base of the left atrial appendage using the occlusion clip while the suction grasper applies tension to the left atrial appendage; and/or egressing the suction grasper via the access port.
