Abstract: A known method for treating pathological body vessels is the implantation of stents as an extended filament, by means of a catheter, which springs into a given form at the implantation site, as a result of its thermo-memory property or its elasticity. The invention relates to a new kind of stent, created in order to improve the flexibility and stability of the stent. This is achieved in that the stent filament or stent filaments are present in the form of at least two opposed spirals. The filament consists of a material with high elasticity or with thermo-memory properties. The stent can be covered with a structure made of pieces of fabric and/or fibers and serves in this way as a stent graft. The new stent demonstrates high stability and flexibility. The stent can be introduced into a body vessel by means of a catheter lumen, which essentially corresponds to the outside diameter of the filaments forming the stent which expands in the point of destination to a larger-lumen tube-shaped implant.
