EXPANDED SPREADER AND A METHOD FOR PRODUCING THE SAME

摘要

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.
