摘要：
A left atrial appendage occluder (10, 20, 30, 40, 50) and a fabricating method therefor. The left atrial appendage occluder (10, 20, 30, 40, 50) comprises an expandable member (11) and barbs (12) on the expandable member (11), wherein the expandable member (11) is woven from elastic metal wires (18) or from elastic metal wires (18) and a metal sheet (21)； and the barbs (12) are formed by flattening a part of the elastic metal wire (18) and engraving, or by engraving the elastic metal sheet (21). In the left atrial appendage occluder (10, 20, 30, 40, 50), the barbs (12) are first fabricated on the elastic metal wires (18) and/or the elastic metal sheet (21), and then the elastic metal wires (18) and/or the elastic metal sheet (21) having the barbs (12) are woven with other elastic metal wires (18) to form the expandable member (11) of the left atrial appendage occluder (10, 20, 30, 40, 50). Therefore, the amount of the barbs (12) is not limited, and multiple barbs can be provided, such that the pressure of the top ends of the barbs (12) is low after the left atrial appendage occluder (10, 20, 30, 40, 50) is implanted into a human body, and the damage caused to the left atrial appendage is small. In addition, the left atrial appendage occluder (10, 20, 30, 40, 50) can be attached with the left atrial appendage better, and the support ability of the expandable member (11) is also improved, to ensure that the structural strength of the left atrial appendage occluder (10, 20, 30, 40, 50) satisfies actual requirements.La présente invention concerne un dispositif d'occlusion de l'appendice auriculaire gauche (10, 20, 30, 40, 50) et son procédé de fabrication. Le dispositif d'occlusion de l'appendice auriculaire gauche (10, 20, 30, 40, 50) comprend un élément extensible (11) et des barbes (12) sur l'élément extensible (11), l'élément extensible (11) étant tissé à partir de fils métalliques élastiques (18) ou à partir de fils métalliques élastiques (18) et d'une feuille méta
