Abstract

The invention relates to a plugging stent for a left auricle. The plugging stent comprises a reticular body and a tail connected with the reticular body, wherein the tail is overturned inwards to forma blunt shape, so that the contact area between the tail and the left auricle is enlarged, the situation that left auricle walls and internal tissue are damaged by the tail end of the stent in the transplanting process and after transplanting is avoided, the damage of the surgery to the patient is reduced, simultaneously, risks of hydropericardium, perforation and the like can also be avoided, and the safety of the surgery operation is higher; and in addition, the maneuverability of the plugging machine is better, and under the situation that the transplanting position is not ideal, the transplanting position can be adjusted only through propelling the plugging machine, so that the operation difficulty is reduced, and the medical care effect is improved.

Description

technical field [0001] The invention relates to the technical field of implantable medical devices, in particular to a occlusion bracket for left atrial appendage Background technique [0002] Atrial fibrillation ("AF" for short) is the most common clinically sustained heart rhythm, and the older you are, the higher the probability of occurrence. When atrial fibrillation occurs, a blood clot forms in the left atrial appendage because of poor blood flow in the atria. Patients with atrial fibrillation are prone to thrombosis, and the chance of thrombosis is 5-6 times that of ordinary people. Therefore, the prevention of atrial fibrillation is of great significance. Currently, patients with nonvalvular atrial fibrillation have a 90% chance of developing a blood clot in the left atrial appendage. Recent studies have shown that closure of the left atrial appendage can effectively prevent the risk of ischemic stroke caused by atrial fibrillation. [0003] The occluders used fo...
