In-vivo efficacy of biodegradable ultrahigh ductility Mg-Li-Zn alloy tracheal stents for pediatric airway obstruction

Wu et al. demonstrate utility of a novel, ultrahigh ductility Mg alloy-based biodegradable stent in vitro and in vivo for use in congenital disorders like pediatric laryngotracheal stenosis. Tested in both bioreactor system and rabbit airway model, these stents display higher corrosion resistance and better in vivo degradation without affecting growth of rabbit airway.
