    • The present invention relates to a medical stent, and in particular to a cardia stent for treatment on the narrow carida of the oesophagus. The cardia stent according to the present invention is woven by wires of shape memory NiTi alloy. There is a drum-shaped locating port at its upper end, and a trumpet-shaped locating port at its lower end. The upper drum-shaped locating port is connected with the lower trumpet-shaped locating port by a supporting net tube. The remaining portions other than the drum-shaped locating port are coated with a membrane of medical flexible material that can be implanted into a human body. The cardia stent comprises at least an anti-reflux valve. The anti-reflux valve is of a triple-petal structure protruding downward that is made from a membrane of medical flexible material that can be implanted into a human body. The cardia stent has the advantages of: difficult to shift, matching with carida anatomy, high anti-reflux ability, easy operation, resisting the corrosion of gastric juice, and it can be used in expansion treatment on the narrow carida caused by variable reasons.
