摘要：: The present invention relates to biodegradable implantable medical device, in particular an endoprosthesis body formed at least partly from a constructional material comprising deformable super-pure magnesium or alloy thereof further comprising one or more super-pure alloying elements. The constructional material has a high formability at room temperature, excellent corrosion stability in vivo, an optimum combination of mechanical properties (strength, plasticity) ideally suited for biodegradable endoprosthesises, particularly stents, as such and for various other technical applications.本發明係關於一種生物可降解之植入性醫療器材，特定言之，至少部分由包含可變形的超純鎂或進一步包含一或多種超純合金元素的其合金之結構材質形成的內置假體。該結構材質具有在室溫下之高變形性、極佳的體內腐蝕穩定性、極適於生物可降解之內置假體，尤其是支架本身及多種其它技術應用的機械性能(強度、塑性)之最佳組合。
