Abstract:
Provided is a biodegradable stent comprising a magnesium alloy free of a rare earth element and aluminum. The stent comprises: a core structure comprising a magnesium alloy containing 90 wt % or more of magnesium as a main component, and zinc, zirconium, and manganese as accessary components, the magnesium alloy being free of a rare earth element and aluminum; a first corrosion resistant layer formed on the core structure and containing magnesium fluoride as a main component; and a second corrosion resistant layer formed on the first corrosion resistant layer and comprising a parylene. A method for producing such a bioabsorbable stent is also provided.
