    摘要： An endoprosthesis includes a plurality of struts defining a flow passage. At least one strut includes (a) a body comprising a bioerodible material and having a thickness and (b) a coating overlying the body. The coating includes a plurality of regions that allow physiological fluids to contact a plurality of corresponding areas of the underlying body when the endoprosthesis is implanted in a physiological environment. The plurality of regions are sized and arranged so that the contacted areas of the body erode substantially through the body in the thickness direction while the coating remains on the body when the endoprosthesis is implanted in the physiological environment.

    摘要： A method includes: providing a tubular substrate in a chamber, the tubular substrate having a lumen, an a luminal surface and a luminal surface; providing a target in the lumen; depositing a first coating onto the abluminal surface and a second coating onto the luminal surface while keeping the tubular substrate in the chamber. An endoprosthesis, such as a stent, including a first coating on at least one portion of its abluminal surface and a second coating on at least one portion of its luminal surface is also disclosed.
