Disclosed is a coated stent comprising (i) a stent framework； (ii) a plurality of layers deposited on said stent framework in dry powder form to form said coated stent； wherein at least one of said layers comprises a bioabsorbable polymer and at least one of said layers comprises one or more active agents； wherein at least part of the active agent is in crystalline form； and wherein forming said layers comprises sintering under conditions that do not substantially modify the activity of said active agent. A method of preparing a coated stent is also disclosed, wherein the method comprises the steps of:(i) providing a stent framework；(ii) depositing a plurality of layers on said stent framework to form said coated stent； wherein at least one of said layers comprises a bioabsorbable polymer； wherein depositing said plurality of layers on said stent framework comprises:discharging at least one pharmaceutical agent and/or at least one active biological agent in dry powder form through a first orifice； depositing the pharmaceutical agent and/or active biological agent dry powder particles onto said framework, wherein an electrical potential is maintained between the framework and pharmaceutical agent and/or active biological agent dry powder particles； discharging the bioabsorbable polymer through said first orifice or through a second orifice； depositing the bioabsorbable polymer in dry powder form onto said framework, wherein an electrical potential is maintained between the framework and the bioabsorbable polymer dry powder particles； and sintering under conditions that do not substantially modify the morphology of said pharmaceutical agent and/or the activity of said bio logical agent.
