Abstract
A novel catheter-based system which ligates the left atrial appendage (LAA) on the outside of the heart, preferably using a combination of catheters and/or instruments, e.g., a guide catheter positioned inside the left atrial appendage which may assist in locating the left atrial appendage and/or assist in the optimal placement of a ligature on the outside of the appendage, and a ligating catheter and/or instrument outside the heart in the pericardial space to set a ligating element at the neck of the left atrial appendage.

63. A device configured for use in a left atrial appendage procedure comprising:
-
an elongate body having a proximal end, a distal end, and a lumen therethrough, wherein the elongate body has a diameter of approximately 24 French or smaller; and an expandable member slidably disposed within the distal end of the elongate member, wherein the elongate member comprises a plurality of arms and wherein the expandable member is capable of displacing tissue in proximity to the left atrial appendage. - View Dependent Claims (64, 65, 66, 67, 68, 69, 70, 71)
