EurekAlert: The procedure, known as LAA occlusion, is performed using the FDA-approved LARIAT(TM) Suture Delivery Device. Doctors access the LAA by inserting a catheter, or thin tube, under the rib cage into the sac around the heart through which the suture to tie off the LAA is delivered. Another catheter is advanced through a blood vessel in the groin up into the heart, and positioned inside the LAA to help guide the suture over the LAA. The outpatient procedure eliminates the number one source of heart related stroke, while avoiding the potentially serious side effects associated with blood thinners.
