A stent ( ) formed from cannula and having flexible segments ( ) and high hoop strength segments ( ) alternating therealong. Axial tie bars ( ) interconnect the segments; minimal length reduction would occur upon expansion. In the high hoop strength segment ( ), struts ( ) are initially parallel in the unexpanded strut condition, while in the flexible segment ( ), struts ( ) extend from a respective bight ( ) to converge at distal ends when unexpanded. In one embodiment, certain adjacent struts ( ) of the hoop segment are spaced apart by a large gap ( ) while others are spaced apart by a small gap ( ). In another embodiment all the struts ( ) of the hoop segment are spaced apart uniformly from each other (or from an axial tie bar) by a small gap ( ), resulting in minimizing the occurrence of fatigue of high-stress sites upon expansion/contraction cycles from continuous pulsatile events.
