The present invention relates to stents to have an improved antiskid function. More particularly it relates to which stent is used to extend censure or the lesion region of a blocking occurs in integrated internal cavity. Stent includes a cylindrical stent, it is with spatial multiplex component, it is knitting or forming across the line made of the super-elastic shape memory alloy in the mesh form in a hollow cylindrical shape, there are more bent-up ends to be formed and heat in a circumferential direction in both ends. Cylindrical stent includes: that the first artificial blood tube layer is placed on total inner surface made of a kind of PTFE materials and its closely More second artificial blood tube layer are placed in its outer surface in a part of predetermined space made of a kind of PTFE materials and closely. First artificial blood tube layer and second artificial blood tube layer packet cylindrical stent are heated and are melted to be adsorbed each other. More first part of component with the space more closed and the second part of the component with the space that more open are formed. The first section pushes away, and insertion hangs over a lesion region, second part hangs over the lesion region of the component of an insertion space.
