Stroke and heart-related diseases are one of the leading causes of deaths in United States. There are many factors that may cause stroke, and left atrial appendage coagulation is one of them. Left atrial appendage coagulation is a coagulation of blood inside the left atrial appendage caused by atrial fibrillation, not rhythmical contraction of your heart muscle. For left atrial appendage, not like other heart defects, anti-coagulant currently is only solution to solve this problem. There isn’t any implant device solution specific for left atrial appendage occlusion. However, there are some devices that are currently going through FDA approval process. These are Watchman and Lariat. According to interviews performed with cardiac specialists throughout Atlanta, they are emphasizing three major factors. They are stability, customizability, and full occlusion. Limitations of Watchman and Lariat are customizability and full occlusion. To satisfy all three factors and to improve from Lariat and Watchman, Flow Medical has come up with innovative left atrial appendage occlusion balloon.
