A statement by its Chief Scientific Advisor, Julio Palmaz, MD

“Personal experience in revolutionizing health care at its foundations gives me the proper perspective to do it again.  The introduction of the balloon-expandable vascular stent in the early 1980’s ushered a new era in vascular therapy and led the way into replacing open surgery with minimally invasive techniques.  Perceived originally as a crazy idea, the eventual acceptance of the stent was largely due to hard work, ingenuity and tenacity.  After achieving wide recognition we never thought that the job was completed or that all new frontiers had been explored. The field of intravascular implants took many turns driven by empirical assumptions and marketing motivations. In my view, the frantic development of the vascular stent neglected its most important attributes: Its surface characteristics and its constituent materials.  The first attribute aims to optimize material-host interaction at molecular level and the second seeks to expand the biomechanical properties to levels higher than achieved by currently used materials”
