Abstract
Methods for occluding an atrial appendage. The steps of an exemplary method include introducing at least a portion of the first device in a heart, introducing at least a portion of a second device into a pericardial space surrounding the heart, positioning the balloon of the first device at least partially within an atrial appendage cavity, inflating the balloon to displace blood present within the atrial appendage cavity, positioning the loop of the second device around the atrial appendage, tightening the loop around the atrial appendage, deflating the balloon to allow for ultimate removal of the first device from the atrial appendage cavity, and separating the loop from the second device so that the loop remains positioned and tightened around the atrial appendage.
