    • An improved medical device for intraluminal endovascular stenting comprises a stent (30) having a hollow cylindrical body fabricated from a plurality of circumferentially extending rings (26a, 26b) having an undulating series of peak (24) and valleys (25). Links (21, 22) join the adjacent rings and are shaped to promote flexibility of the stent during its delivery to a treatment site and adequate scaffolding of a vessel following its deployment at the treatment site. Improved access to side-branches off the vessel is achieved by providing enlarged cell size for the stent when expanded, whilst maintaining adequate scaffolding. This is achieved by interrupting the straight sections between adjacent peaks and valleys by an inflection point at which one arm (21a, 21b) of one link is connected to join adjacent rings together.
