Left atrial appendage manipulation and traction

A method of positioning an occlusion clip proximate a left atrial appendage, the method comprising:

• creating an access port allowing communication between an exterior of a human body and an interior of the human body 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 the 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;
• overcoming a bias of the occlusion clip to open the occlusion clip, where the occlusion clip is biased closed, and position dual beams of the occlusion clip at least partially around the left atrial appendage;
• discontinuing overcoming of the bias of the occlusion clip to clamp a base of the left atrial appendage using the dual beams of the occlusion clip while the suction grasper applies tension to the left atrial appendage;
• and
• disconnecting the suction grasper from the left atrial appendage and egressing the suction grasper via the access port to the exterior of the human body.
