Each set of the strut members is longitudinally displaced from each other and connected to each other by longitudinally extending links. Each set of the strut members forms a closed and cylindrical portion of the stent. Further, each set of the strut members includes a plurality of connected curve sections and diagonal sections. The sets of the strut members further include end sets of strut members located at each end of the stent and central sets of strut members located between the end sets of the strut members.
