Left auricle occlusion device with high adaptability

Abstract

The invention relates to the technical field of medical apparatuses, in particular to a left auricle occlusion device with high adaptability. The left auricle occlusion device comprises an occlusion disc, an anchoring part and a connecting part connected with the occlusion disc and the anchoring part; the left auricle is occluded by the occlusion disc, wherein through the arrangement of a support disc rack and a choke membrane, compared with other occlusion discs weaved by metal, the occlusion disc is smaller in retracted size and lighter in weight, and the choke membrane is used for stopping blood from entering and leaving the left auricle; particularly the design of a cuff is unique, specifically the cuff is arranged on a support ring at the periphery of the support disc rack in a sleeving mode, the cuff is filled with an elastic material during an operation, when the cuff is matched with the left auricle opening, since the cuff filled with the elastic material is good in elasticity and roughness, the irregular shape of the left auricle opening can be adapted to, the left auricle opening is completely occluded, the problem is solved that a traditional occlusion device cannot solve the problem that the left auricle opening is not tightly occluded in different cases, and the hidden danger is thoroughly eliminated that the thrombus is formed at the left auricle part due to atrial fibrillation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a left atrial appendage occluder with strong adaptability. Background technique [0002] In the field of cardiovascular and cerebrovascular medicine, atrial fibrillation is the most common clinical persistent arrhythmia. Atrial fibrillation leads to thromboembolism, which in turn leads to symptoms such as palpitations, chest tightness, and dizziness. The biggest hazard is stroke, which can be fatal or severe. Disabling, seriously affecting people's health and quality of life. Therefore, stroke prevention is the fundamental goal of AF treatment. [0003] The left atrial appendage (LAA) is an important part of the origin of thromboembolism in patients with atrial fibrillation (AF). 60% of patients with rheumatic heart disease and atrial fibrillation have cardiogenic thrombus from the left atrial appendage. Patients with non-valvular atrial fibrillation More than 90% of th...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a left atrial appendage occluder with strong adaptability. On the one hand, it solves the problem that the existing left atrial appendage occluder will still cause thrombus when there is a gap between the left atrial appendage and the left atrial appendage. On the other hand, it solves the problem that the large size of the existing occluder causes the delivery sheath to be thick and easy to cause damage to human blood vessels
