The present invention provides a stent including a tubular body having a plurality of reservoirs disposed therein and a therapeutic agent located in the reservoirs or located in the reservoirs and on a surface portion of the tubular body, wherein the stent is free of polymeric material. The invention also provides a drug-eluting stent made from the process of providing a polymer-free stent body having a plurality of reservoirs disposed therein, diluting a therapeutic agent in a polymer-free solvent to form an agent-solvent mixture, coating the stent with the agent-solvent mixture, and allowing the solvent to dissipate from the stent thereby leaving the agent disposed on the stent.
