Abstract
An implantable medical device includes a bioerodible portion adapted to erode when exposed to a physiological environment. The bioerodible portion includes an alloy comprising at least 10 weight percent chromium and has an outer surface having a ratio of chromium oxide to chromium metal of less than 5. The bioerodible implantable medical device can be created by implanting metallic ions into an alloy including at least 10 weight percent chromium to define an outer surface of a medical implant, or precursor thereof.
