A stent comprises a plurality of serpentine circumferential bands and a plurality of connector columns. Each connector column is located between two adjacent serpentine circumferential bands and comprises a plurality connector struts. Each connector strut is connected at one end to one serpentine circumferential band and at another end to another serpentine circumferential band. Each connector strut has step sections and at least one riser. Each step section extends substantially in a circumferential direction and each riser extends in a substantially longitudinal direction. The steps in a connector are connected to one another via a riser. |
