PROBLEM TO BE SOLVED: To provide an internal stent capable of moving from a collapsed condition to an expanded condition without significant twisting but which facilitates flow within the stent supported fluid conduit to swirl. SOLUTION: There is provided a stent 2 for insertion in a fluid conduit of the human or animal body when the stent is in a collapsed condition and for expansion to an expanded condition. The stent includes an outer wall 7 for engagement with the conduit, the outer wall 7 has a helical portion 6 which in the expanded condition extends longitudinally and circumferentially, and which, upon expansion of the stent from the collapsed condition to the expanded condition resists extension.
