Abstract
An atrial septal defect occluder, including: a body (), including two disk surfaces arranged opposite to each other and provided with a through hole () along an axial direction of the body (); and a blocking assembly, including an openable choke film () or elastic body (), the blocking assembly being in contact with the body (), wherein when the blocking assembly is in a closed state, the blocking assembly impedes liquid from flowing in the through hole (), and when the blocking assembly is in an open state, the blocking effect is weakened or even eliminated, thus allowing a minimally invasive interventional device to pass through the occluder by means of the through hole (). By means of the interaction between the through hole () in the body () and the blocking assembly of the occluder, the occluder may not only seal an atrial septal defect, but may also achieve the function of allowing a minimally invasive interventional device to pass by means of the through hole () when necessary, thus preventing repeated perforation treatments.
