In atrial fibrillation, an atrium loses the contractile function, blood is easy to stagnate in the atrium, particularly in the left auricle to form thrombus, and after the thrombus falls off, the thrombus can flow to all parts of the body along with the blood, so cerebral embolism, limb arterial embolism and the like are caused, cerebral apoplexy and limb paralysis are caused, and patients with severe symptoms are half-born or whole-body paralysis, and even need to amputate. In patients with atrial fibrillation, more than 90% of thrombi are closely associated with the left atrial appendage; and as the most common persistent arrhythmia, atrial fibrillation has a prevalence of 0.5% to 1.5% in the general population. The left atrial appendage is blocked to prevent the formation of thrombus in the left atrial appendage during atrial fibrillation, thereby reducing the risk of long-term disability or death caused by thromboembolism in patients with atrial fibrillation.

Because the shape of the left auricle shows that the difference is great among different individuals, the existing occluder is difficult to adapt to the requirements of different individuals, partial residual leakage is easy to occur when the left auricle is occluded, the left auricle can not be completely closed, and the formation of thrombus in the left auricle can not be completely and effectively prevented. Therefore, the existing left atrial appendage occluder has the defects of poor occlusion effect, low applicability and the like.
