Figure 1: Characteristics of the new generation metallic stents and BRS developed with nanotechnologies. Panel demonstrates different generations of stents and BRS. In addition, some representatives of the new fourth generation are shown, utilizing polymer-free technologies with drug-loading in micro- and nanopores (LepuNano+), micro-reservoirs (Cre8), stents coated with CD34+ cells-catching system (Genous), stents with lipid-based nanocarriers (Focus NP) and ultra-thin nanoplatforms (Mitsu).
