Abstract

Boston Scientific Interventional Cardiology Division is exploring the feasibility ofbiodegradable metal stents. In particular, iron is of interest based on reportedbiocompatibility and degradation rate. Boston Scientific is performing IR&Dexperimentation to generate data upon which a recommendation can be made tothe investment board regarding the technical viability of this stent concept. One ofthe challenges discovered was that in-vitro degradation rates of the candidatemetals do not agree with observations from in-vivo experiments. One of the keydesign criteria for a degradable stent is the degradation behavior. In order to beable to assess the feasibility of these stent materials, it is necessary to understandthe time rate of mass and strength loss.
