摘要：
A replaceable left atrial appendage occluder includes a stepped balloon and an occlusion disc. The left atrial appendage orifice occlusion portion of the stepped balloon is configured to completely occlude the left atrial appendage orifice. The left atrial anchor portion of the stepped balloon is configured to be clamped on the left atrial wall to prevent the left atrial appendage occluder from shifting. The occlusion disc is released in the pericardial cavity, and is connected to the stepped balloon by the connecting column of the occlusion disc, so that the left atrial appendage is pressed and occluded between the stepped balloon and the occlusion disc. The stepped balloon occludes the left atrial appendage orifice. The surface of the stepped balloon is smooth and coated with an anticoagulant coating.
