Intravascular devices are an integral component of modern-day medical practice. They are used to administer intravenous fluids, medications, blood products and parenteral nutrition. In addition they serve as a valuable monitor of the haemodynamic status of critically ill patients. Over the past 2 decades the focus of research and development in this field has been the physicochemical properties of catheters, looking at such aspects as improved catheter materials, tensile strength, rupture resistance, biocompatibility and the creation of catheter micro-environments hostile to invading organisms.
