A wavily deformable stent includes a hollow cylindrical net body formed of elastically deformable wires interlaced with each other. The net body extends in a longitudinal direction and terminates at open opposite ends. The net body has at least one high-rigidity section and at least one low-rigidity section less rigid than the high-rigidity section. The high-rigidity section and the low-rigidity section are arranged continuously and alternately along the longitudinal direction. The stent is wavily deformed and held in place against unwanted displacement when situated inside a stenosed part of a bodily organ. Also provided is a method for producing the wavily deformable stent.
