摘要
A biocompatible metallic material may be configured into any number of implantable medical devices, including intraluminal stents. The biocompatible metallic material may comprise a magnesium alloy. The magnesium alloy implantable medical device may be designed to degrade over a given period of time. In order to control the degradation time, the device may be coated or otherwise have affixed thereto one or more coatings, one of which comprises a material for controlling the degradation time and maintain a pH neutral environment proximate the device. Additionally, therapeutic agents may be incorporated into one or more of the coatings on the implantable medical device.
