Abstract
An occluder includes a proximal occlusion portion. The proximal occlusion portion has a proximal end provided with a first converged member, and is provided with a conical guide structure on an outer periphery of the first converged member. The guide structure has an inner diameter gradually decreasing from a distal end to a proximal end. The guide structure provides a guiding performance to facilitate the occluder to be withdrawn into the sheath easily. An occluder fastening system is used in cooperation with the occluder.
