Non-absorbable metallic stents are commonly used in pediatric pulmonary artery and coarctation stenting to assist revascularization and to prevent potential restenosis. As conventional stents are quickly “outgrown” by pediatric patients, there remains a need for a pediatric resorbable stent. A stent made from a material with the ideal mechanical properties, biocompatibility and corrosion rate would be of huge benefit to thousands of children with congenital heart disease. In this study, micro Zn-Mg wires were characterized in terms of mechanical properties by tensile testing and micro/nano-hardness testing and biodegradability by in vitro corrosion in a pseudo-physiological solution. The experimental results suggest that this novel material could have the ideal strength, ductility and resorption for stent applications.
