ABSTRACT:
An expandable stent comprises a multiplicity of sets of strut members. Each set of strut members forms a circumferentially extending closed structure with adjacent sets of strut members being coupled each to the other by connectors. The stent has two types of sets of strut members, a first type of set of strut members and a second type of set of strut members. The first type of set of strut members has a shorter total pathlength about the periphery of the stent than the second type of set of strut members. When the stent is radially deployed to its nominal diameter, the first type of set of strut members has greater radial rigidity as compared to the second type of set of strut members.
