STENT

A stent having an improved anti-sliding function is proposed. The stent includes inner and outer stents that have undergone heat treatment and have several spaces formed by weaving or crossing wires made of a superelastic shape memory alloy in a hollow cylindrical net shape, in which the outer stent is shorter than the inner stent and has an enlarged section having a diameter larger than the inner stent and a bending section formed by bending inward a side of the enlarged section; and a pair of outer stents are fitted on both ends of the inner stent such that a pair of enlarged section face each other, and spaces of the inner stent and spaces of the bending sections are connected by a connection thread, whereby a space section is defined between the inner stent and the outer stent.
