The present invention relates to a linking stent and to a production method for same, and the invention comprises: a main body which is provided in the shape of a hollow cylinder, and in which a plurality of cells are formed by means of intersection through wires; an upper head which is formed extending from one end of the main body, with a diameter that expands more than the diameter of the main body; and a lower head which is formed extending from the other end of the main body, with a diameter that expands more than the diameter of the main body, characterized in that the upper head and the lower head are provided so as to respectively abut inside two different types of tissue. Consequently, the present invention makes it possible to produce a stent which forms a bypass by linking between two different types of tissue, and which is able to impart minimal axial force and sufficient expansion force to maintain the bypass formed. |
