Problems solved by technology
[0006] In order to improve the deficiencies of the prior art, the object of the present invention is to provide a left atrial appendage occluder and a left atrial appendage occluder system to solve the problem that the existing left atrial appendage occluder cannot be tightly attached to the left atrial appendage in the prior art. The inner wall of the opening will affect the sealing effect, resulting in shoulder leakage and even residual shunt; the second is to set the bottle cap structure to be implanted behind the structural support to increase the sealing effect, and to seal the tissue around the left atrial appendage. The larger shape is likely to touch other parts near the left atrial appendage, causing technical problems affecting other parts

The invention relates to a left auricle plugging device and a left auricle plugging system. The left auricle plugging device comprises a supporting skeleton and a plugging membrane, and the supporting skeleton is wrapped by the plugging membrane; the supporting skeleton is in a screw cap shape, and comprises a disc portion and a cylinder portion connected with the disc portion, the projection of the section of the cylinder portion is located in that of the section of the disc portion, one end of the cylinder portion is connected with the disc portion, and the other end of the cylinder portion is an open end; the supporting skeleton is made from shape memory alloy materials; an anchor hook is arranged on the outer side of the cylinder portion of the supporting skeleton and used for hooking the inner wall of a left auricle after the left auricle plugging device is planted to fix the left auricle plugging device. Compared with an existing left auricle plugging device, the left auricle can be better plugged through the left auricle plugging device, and omalgia and residual shunt are avoided; the structure of the disc portion is small and will not touch other parts nearby the left auricle, so that influences on other parts are avoided.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a left atrial appendage occluder and a left atrial appendage occluder system. Background technique [0002] As the most common persistent arrhythmia, the incidence of atrial fibrillation in the general population is 0.5% to 1.5%. Data show that in patients with atrial fibrillation, more than 90% of the thrombus in non-valvular atrial fibrillation originates from the left atrial appendage. Therefore, it is obviously reasonable to prevent thrombosis by resection or closure of the LAA. [0003] Left atrial appendage closure is currently a new trend in the treatment of stroke prevention in patients with atrial fibrillation around the world. It can effectively reduce the mortality and disability of patients, and reduce the occurrence of bleeding at the same time. The main purpose of left atrial appendage occluder is to prevent stroke caused by atrial fibrillation. Since the ...
