Abstract: A fistula blocking stent, a stent delivering system, and a method of delivering a fistula blocking stent are provided. The fistula blocking stent is configured to seal a fistula formed between a first lumen and a second lumen, which includes a first fixing stent in a shape of a hollow tube, the first fixing stent having a proximal end, a distal end, and a first tube extending axially between the proximal end and the distal end, the first fixing stent being provided in the first lumen; a second fixing stent provided in the fistula and the second lumen, the second fixing stent having a first end and a second end opposite to the first end, the first end being connected to the first fixing stent; and a barrier film provided on at least one of the first fixing stent and the second fixing stent and configured to seal the fistula.

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.
