A biodegradable occluder of a parachute design. The end close to a human body is defined as a proximal end, and the end away from the human body is defined as a distal end. The occluder comprises an occluder support (1) internally provided with a flow-choking membrane (2), and a state-variable forming ring (4). The occluder support (1), the flow-choking membrane (2), and the forming ring (4) are made of macromolecule polymer materials having biodegradable properties in biological tissues. The occluder is made of the biodegradable polymer materials, so that the occluder can be decomposed or absorbed by human tissues after a period of time in the human tissues, defect parts can be finally formed by the human tissues, and therefore, occlusion without foreign matters can be realized, and the benefits are particularly obvious for children.
