A modular stent assembly (20) is provided with stent sections (22-26) which are coupled together by a coupling arrangement formed of first (30) and second (32) coupling elements. The first and second coupling elements (30, 32) provide a strong coupling between adjacent stent sections (22-26) which behaves in a manner substantially identical to the conventional unitary tie bar. The modular nature of the stent assembly (20) reduces manufacturing costs, can provide for replacement of only a defective part of the assembly 20 and can facilitate the assembly of a stent having differing characteristics along its length optimised for a particular medical application.
