Abstract: A left atrial appendage occlusion device and a delivery system are provided, wherein the left atrial appendage occlusion device includes a stent and an occluder. Firstly, the stent is implanted and fixed at the entrance of the left atrial appendage; then, a double-disc occluder is released on the stent to occlude the left atrial appendage. The left atrial appendage occlusion device includes a self-expandable nitinol stent, which is firmly fixed at the entrance of the left atrial appendage via a two-way anchoring thorn, and then an occluder is released on the stent. The left atrial appendage occlusion device is delivered to the left atrial appendage by the delivery system. Compared with the prior art, the delivery system improves the releasing accuracy and the implanting stability of the occluder. After being released, both the stent and the occluder can be withdrawn into a catheter to be relocated or replaced.
