Abstract
The present invention relates to a Left atrial appendage occluder comprising an elastic closure disc. The left atrial appendage occluder also comprises an elastic fixing frame connected with the closure disc and located on one side of the closure disc. The fixing frame comprises a central end connected with the closure disc and a plurality of interconnected and bent struts, wherein at least one anchor is set near the end of at least one strut with the anchor pointing 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.
