Lariat II Suture Delivery Device
From the inside of the heart a balloon is placed inside the Left Atrial Appendage to expand it and make it accessible to the noose device which is inserted from the outside of the heart. The positioning balloon is withdrawn before the Lariat noose is closed around the base of the Left Atrial Appendage.
The noose completely closes off the Left Atrial Appendage which dies and is no longer electrically active. The Lariat II snare device has been approved by the FDA (Lariat II, SentreHeart, Inc., Palo Alto, CA). A noose device to close off the Left Atrial Appendage is inserted from outside the heart, unlike for example the Watchman device which is inserted into the LAA from inside the heart. It is used in cases where the patient cannot tolerate anticoagulants like Coumadin. (The Watchman device requires a patient be on anticoagulants for a couple of months.)
The Lariat device was invented by Dr. William E. “Billy” Cohn, Director of Minimally Invasive Surgical Technology at the Texas Heart Institute at St. Luke’s Episcopal Hospital.
