A stent for positioning in a body lumen having a cylindrical shape extending along a longitudinal axis surrounded by a stent wall which defines a diameter of an axial passage communicating with openings on two opposite ends of the stent. The wall is configured so as to be elastic under tension whereupon an exertion of a tensile force acting on one of the ends of the stent in a longitudinal direction decreases the diameter of the stent, such that the stent may be removed.
