Abstract
Disclosed is an occluding stent. The occluding stent includes a distal flange occluding body, a proximal flange occluding body, and a connection portion. External surfaces of the distal flange occluding body and the proximal flange occluding body are both provided with a coating. An external surface of the connection portion is wholly or partially provided with a coating. A first occluding coating is provided between the distal flange occluding body and an inner cavity of the connection portion. The present invention overcomes the defect that the existing occluder device for closure of an esophagobronchial fistula is harmful to surrounding tissues, makes the device retractable, enhances the safety of the device, and improves life and treatment of patients. A new safe and effective treatment method for an esophagobronchial fistula is provided.
