The support structure of the stent is composed of at least two zigzag-shaped wires which extend parallel to the longitudinal axis of the casing of the stent and which are offset relative to each other on the circumference of the casing, wherein each wire has at least three legs and the middle leg includes an acute angle with each of the two adjoining legs.
