High radial stiffness and longitudinal flexibility are essential mechanical properties of a stent. A stent consists of cell and link, which is minimal structure unit. Mechanical properties of a stent are depended on these configuration and dimension. In this paper, the relation between mechanical properties and the longitudinal length of cell and link was investigated. Six stents were constructed and measured the bending stiffness using 4-points bending test machine. The result showed that the bending stiffness decreased with the cell-link length ratio (B/A). The result was-not consistent with the numerical analysis. The disagreement suggests that the deformation mode under bending condition changes with B/A.
