Paper Title:
Nanostructured Calcium Phosphate Coating for Stents
  Abstract

A nanoporous calcium phosphate (CaP) coating on metallic surfaces is presented. The coating consists of a stack of (a) a TiNbN layer deposited by physical vapor deposition and acting as diffusion barrier against allergenic ions, (b) a SiO2 xerogel layer providing good adhesion properties and designing the nanoporosity of the outer CaP layer (c) precipitated electrochemically. SEM results verified a homogeneous nanoscale porous structure of the CaP coating. It is characterized by a high adhesion strength. If applied to stent covering the nanoporous CaP coating has promising properties to initiate rapid endothelium formation and reduced risk of restenosis.
