Abstract
A stent suitable for deployment in a blood vessel to support at least part of an internal wall of the blood vessel comprises a plurality of longitudinally spaced-apart annular elements, and a plurality of connecting elements to connect adjacent annular elements. Each connecting element is circumferentially offset from the previous connecting element. Upon application of a load to the stent, the stent moves from an unloaded configuration to a loaded configuration. In the unloaded configuration the longitudinal axis of the stent is straight, and the stent is cylindrically shaped. In the loaded configuration the longitudinal axis of the stent is curved in three-dimensional space, and the stent is helically shaped.
