Abstract
A left atrial appendage occluder for improving sealing effect and a manufacturing method thereof are provided. The left atrial appendage occluder includes a sealing portion and an anchoring portion coupled to the sealing portion. The sealing portion and the anchoring portion abut against each other. A tight connection between the sealing portion and the anchoring portion can be achieved by applying a pre-tightening force, such that the left atrial appendage occluder can be better attached to and occlude the left atrial appendage after being release.
