Problems solved by technology

[0004] However, due to the large volume and dense mesh of the existing occluder, it almost occupies the entire interatrial septum after being implanted in the human body. It becomes impossible to puncture the atrial septum to send the sheath (φ3-9mm) into the left atrium, which makes the patient lose the intervening channel of the atrial septum, and also loses the minimally invasive interventional treatment of atrial fibrillation, mitral regurgitation and other diseases Opportunity

Abstract

The invention provides a plugging device, and relates to the field of medical equipment, and the plugging device comprises: a plugging device body which is provided with a through hole, wherein the through hole extends along the axial direction of the plugging device body; and a flow blocking film which is arranged in the through hole so as to separate and block the through hole. Compared with the prior art, the plugging device keeps the structure and the working principle of a traditional plugging device, safety and effectiveness of the plugging device are guaranteed, the totally-closed sheet-shaped flow blocking film is arranged in the central through hole, blood flow is blocked from passing through the plugging device, meanwhile, the flow blocking film is easy to puncture and expand by means of the thin and brittle characteristics of the flow blocking film, therefore, the sheathing canal can be easily punctured and fed from the central through hole of the plugging device, and a channel is reserved for follow-up atrial septum puncture interventional operation.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an occluder. Background technique [0002] Atrial septal defect is a common congenital heart disease. At present, the mainstream treatment method is percutaneous (femoral vein) atrial septal occlusion with an occluder. In this operation, the occluder is one of the most important medical equipment. [0003] As shown in the occluders currently used, they are all Nitinol alloy braided double-disc and one-waist "I"-shaped structures, and their safety and effectiveness have been widely clinically confirmed. Most of the patients undergoing atrial septal defect closure are young patients, and there is a high probability of complications such as atrial fibrillation and mitral valve regurgitation in the later stage. For these concurrent diseases, radiofrequency ablation, left atrial appendage closure, and mitral valve clipping can be used. Venous repuncture of the interatrial septum int...
