摘要： The present invention relates to a connection stent and a method of manufacturing the stent. The connection stent includes: a body configured to form a plurality of cells through the intersection of wires, and provided in a hollow cylindrical shape; an upper head formed to extend from one end of the body to have a diameter larger than that of the body; and a lower head formed to extend from a remaining end of the body to have a diameter larger than that of the body. The upper head and the lower head are respectively placed to come into contact with insides of heterogeneous tissues. Accordingly, according to the present invention, there can be manufactured a stent which can connect heterogeneous tissues and form a bypass and which can provide sufficient expansion force and minimum axial force for the maintenance of the bypass formed as described above.
