DEVICES, SYSTEMS, AND METHODS FOR CLOSING THE LEFT ATRIAL APPENDAGE
First Claim
1. A method for closing a left atrial appendage comprising:
- advancing a first guide through the vasculature, into the left atrial appendage, and out of the left atrial appendage;
advancing an expandable member into the left atrial appendage;
expanding the expandable member;
advancing a left atrial appendage closure device adjacent to the left atrial appendage from outside the heart, wherein the closure device comprises an elongate body and a closure element comprising a loop; and
closing the neck of the left atrial appendage with the closure element.

Abstract
Described here are devices, systems and methods for closing the left atrial appendage. Some of the methods described here utilize one or more guide members having alignment members to aid in positioning of a closure device. In general, these methods include advancing a first guide having a first alignment member into the left atrial appendage, advancing a second guide, having a second alignment member, into the pericardial space, aligning the first and second alignment members, advancing a left atrial appendage closure device into the pericardial space and adjacent to the left atrial appendage, and closing the left atrial appendage with the closure device. In these variations, the closure device typically has an elongate body having a proximal end and a distal end, and a closure element at least partially housed within the elongate body. The closure element comprises a loop defining a continuous aperture therethrough.
