An expandable stent for insertion into a body lumen has a generally cylindrical
lattice structure formed from wall segments that intersect and with some of the
intersections being interrupted to enhance the flexibility of the stent. The wall
segments associated with the interrupted portions are formed to have an outward
flare such that when the stent is in a curved configuration, the wall segments
will not project radially inwardly into the stent lumen, thereby avoiding obstruction
to flow through the lumen.
