Abstract

A left atrial appendage occluder comprises an elastic closure disc, and a supporting structure connecting with the closure disc and being located on one side of the closure disc, with the supporting structure comprising a central end connecting with the closure disc and a plurality of interconnected and bent struts, wherein at least one anchoring thorn is set near the end of at least one strut with the anchoring thorn toward the closure disc. The left atrial appendage occluder has a stable structure, a good positioning and sealing effect on the cavity wall in the left atrial appendage, and it is easy to position repeatedly; it can also be recycled before separating from a conveyor. When in surgical operation, the left atrial appendage occluder can select the position area based on the actual shape and size of the patient's left atrial appendage, so the surgical risk is lowered.
