A stent insertable in a body vessel, the body vessel defining a vessel wall. The stent includes a plurality of struts, the struts defining a substantially elongated stent passageway, the struts being configured, sized and operatively coupled to each other in a manner such that the stent is deformable between a first configuration and a second configuration. In the first configuration, the stent passageway has a first radial dimension and a first longitudinal dimension, and in the second configuration, the stent has a second radial dimension and a second longitudinal dimension, the second radial dimension being at least as large as the first radial dimension and the second longitudinal dimension being larger than the first longitudinal dimension. The stent is able to expand substantially longitudinally with the body vessel as the body vessel grows without reducing in diameter so as to reduce risks of damaging the vessel wall as the body vessel grows.
