Abstract
A stent implantation arrangement comprises a stent (18) mounted upon a balloon (10), the stent (18) extending over regions (12, 14) of the balloon (10) of different diameters, when the balloon occupies an inflated condition. A stent (18) particularly suitable for use in the implantation and deployment arrangement includes regions of different radial resistance to expansion.
