A method of making a stent which, when the stent is inserted in a fluid conduit of the human or animal body defines a flow lumen following a non- planar curve, the method comprising providing a tubular hollow structure having a longitudinally extending cavity and made of a shape memory material, modifying the shape of the hollow structure into a shape in which its longitudinally extending cavity follows a non-planar curve, heating the modified hollow structure to a temperature such that the modified shape is memorised by the shape memory material, and cooling the hollow structure. |
