摘要：
A replaceable left atrial appendage occlusion assembly and an implanting method thereof are provided. The left atrial appendage occlusion assembly includes a stepped balloon (2) and an occlusion disc (3). The left atrial appendage orifice occlusion portion (211) of the stepped balloon (2) is configured to completely occlude the left atrial appendage orifice. The left atrial anchor portion (212) of the stepped balloon (2) is configured to be clamped on the left atrial wall to prevent the left atrial appendage occlusion assembly from shifting. The occlusion disc (3) is released in the pericardial cavity, and is connected to the stepped balloon (2) by the connecting column (31) of the occlusion disc (3), so that the left atrial appendage is pressed and occluded between the stepped balloon (2) and the occlusion disc (3). The stepped balloon (2) occludes the left atrial appendage orifice. The surface of the stepped balloon is smooth and coated with an anticoagulant coating. The left atrial appendage occlusion assembly can occlude various types of left atrial appendages, and prevent the formation of thrombosis. In this way, patients do not need to take anticoagulant drugs after the procedure.
