The present invention relates to a stent for intraluminal expansion. The stent for intraluminal expansion comprises an inner stent A, an outer stent B and fixing threads C for fixing these stents as one unit. The outer stent B is inserted over the inner stent A in such a way that the space portions of the inner stent A and the space portions of the outer stent B are alternated with each other, so the outer surface of the inner stent and the inner surface of the outer stent are in close contact with each other, and both ends of the outer stent and inner stent are fixed as one unit by fixing threads C. According to the stent for intraluminal expansion of the present invention, in which form recoverability of each of the inner stent A and the outer stent B is excellent, expansion is easy after it is inserted into the lumen body because the cylindrical film membrane is not fixed by fixing thread C, and the space portions Id of the inner and outer stents are overlapped alternately with each other so that it is possible to effectively prevent cancer cells, etc. from penetrating into the lumen. |
