Stent performance can be evaluate the sum of radial-force and bending-stiffness. These mechanical properties depend on stent structures (for examples, longitudinal length of cell and link). The objective of this paper was to investigate the influence between longitudinal lengths of cell (A) and link (B) and these mechanical properties using numerical analysis. Cell-link-cell model was developed, because stent consists of repeat structure. As results, both radial-force and bending-stiffness curve with B/A were quadratic curves. Stent total performance, which was defined as the sum of radial-force and bending-stiffness, was superior and fluctuated a little in 0.5-1.0 of B/A.
