Medical Arterial Stents

Surface Metrology — Improving Medical Stent Biocompatability & Refining Arterial Stent Surface Characteristics

Each year millions of life-saving medical stents are implanted in patients worldwide. Inspection of these arterial stents must be rapid, accurate, and nondamaging, performed not only on the outside surface of the stents but on the inside as well. Critical parameters for medical stents include widths, feature shape and radius of curvature of the device. In addition, surface roughness must be minimized in order to avoid physical damage to the treated vessel and to ensure good adhesion of the coatings. Potential defects include broken struts, scratches, pits, improperly carved junctions, surface contamination, and incorrect thickness and uniformity of the various coating layers. Only optical profiling offers the required combination of flexibility, speed, and reliable results to enable high-volume measurement of both the stent and its outer drug coating. This method promises higher quality and lower cost as manufacturers refine their processes based on the metrology feedback, which in turn may enable even greater use of the devices.
