摘要： The present invention provides a parachute-shaped biodegradable occluder, with a proximal end adjacent to a human body and a distal end far away from the human body. The parachute-shaped biodegradable occluder includes an occluder stent internally provided with a baffle film, and a shapeable ring with changeable states. The occluder stent, the baffle film and the shapeable ring are respectively made of polymer materials being degradable in biological tissues. The occluder is made of a biodegradable polymer material, which is degradable or absorbable by human tissues after being implanted for a period of time to make a defect site composed of human tissues, realizing occlusion without foreign matter. The occlusion effect is particularly significant for children.
