A drug-coated stent and a method for fabricating the stent are disclosed. The stent has an originally flat pattern and connection points where the sides of the flat pattern are joined. The method includes the steps of a) cutting a stent pattern into a flat piece of metal thereby to produce a metal pattern, b) spraying the flat metal stent pattern with a polymer and a drug, c) deforming the metal pattern so as to cause two opposing sides to meet, and d) joining the two opposing sides a least at one point. Substantially no portion of the stent projects into the lumen of the stent when the stent is expanded against the internal wall of a blood vessel. |
