Strut and Bridge Thickness
Strut and bridge thicknesses of the expanded finished stent are measured by direct measurement using a calibrated optical system. Strut and bridge thickness are measured at the stent mid-length and near each end, at two circumferential locations at each axial location. If strut and bridge thicknesses are systematically different by design, they will be measured and reported separately. Direct measurement may require test samples destruction by cutting, or flattening, or both.
