Abstract
An atrial appendage occluder capable of entering a half-released state by means of pushing a head-end fiber comprises: an occlude body (); a head-end control fiber (); and a tail-end control fiber (). A head end of the occluder body () is connected to one end of the head-end control fiber () by means of a head-end threaded bushing (). A tail end of the occluder body () is connected to one end of the tail-end control fiber () by means of a tail-end threaded bushing (). The tail-end control fiber () is in the form of a hollow column. The other end of the head-end control fiber () sequentially passes through the tail-end threaded bushing () and the tail-end control fiber (). The occluder body () is in a woven-net support structure, and has a shape preconfigured to match the structure of an atrial appendage after the occluder body () has been fully released. The occluder body () is in the form of a strip and disposed in an outer sheath () before being released. The occluder body () is in a half-release state after being pushed out of the outer sheath (). The diameter of the occluder body () is changed by pushing or pulling the head-end control fiber (). The atrial appendage occluder can adjust its location in the atrial appendage, such that the occluder can be released precisely in a preset location.
