Radius of original and optimal stents during dilatation process. In first load phases 0–25 ms, both original and optimal stents were expanded gradually, but the struts didn’t reach the vessel wall until stents were fully expanded. In the second load phases 25–32 ms, the radius of the stents remained at a constant level. In the third load phases 32–42 ms, there was a small radial elastic recoil of stent, which occurred about 32–34 ms. a Diamond-shaped stent: the radial of normal vascular is 2.25 mm, b sv-shaped stent: the radial of normal vascular is 1.65 mm
