Devices, systems, and methods for inverting and closing the left atrial appendage

A method for inverting an atrial appendage, comprising the steps of:

• inserting at least part of a catheter system into an atrial appendage, the catheter system configured to suctionally engage an apex of the atrial appendage;
• applying suction through at least part of the catheter system so to suctionally engage the apex of the atrial appendage;
• retracting at least part of the catheter system under suctional engagement so to cause the apex of the atrial appendage to fold inward about itself, causing exterior sides of the atrial appendage to be adjacent to one another;
• and
• injecting a biologically-compatible glue through side holes of a closed-end needle inserted through the apex of the atrial appendage so that the biologically-compatible glue causes the exterior sides of the atrial appendage to effectively adhere to one another.
