A method of coating a stent comprising: mounting a stent on a holder in a coating chamber that imparts a charge to the stent, providing a first cloud of charged particles of polymer to the stents by rapidly expanding a pressurized solution of the polymer in densified 1,1,1,2,3,3-hexafluoropropane through a first orifice, wherein the polymer comprises PLGA, wherein a first polymer layer of the polymer particles is formed on the stent by electrostatic deposition, sintering the first polymer layer at >40°C in ambient pressure, providing a first cloud of charged sirolimus particles to the stents having an opposite charge than the charge of the stent by pulsing sirolimus particles into the chamber using a propellant in order to deposit a first agent layer on the stent, wherein at least a portion of the sirolimus particles is in crystalline form, providing a second cloud of charged particles of the polymer and a third cloud of charged particles of the polymer to the stents by sequentially rapidly expanding the pressurized solution through the first orifice, wherein the particles have an opposite charge than the charge of the stent, wherein a second polymer layer of the polymer particles is formed on the stent by electrostatic deposition, sintering the second polymer layer at >40°C in ambient pressure, providing a second cloud of charged sirolimus particles to the stents having an opposite charge than the charge of the stent by pulsing the sirolimus particles into the chamber using a propellant in order to deposit a second agent layer on the stent, wherein at least a portion of the sirolimus particles is in crystalline form, providing a fourth cloud of charged particles of the polymer, a fifth cloud of charged particles of the polymer, and a sixth cloud of charged particles of the polymer to the stents by sequentially rapidly expanding a pressurized solution through the first orifice, wherein the particles have an opposite charge than the charge of the stent, wherein a third polymer layer of the polymer particles is formed on the stent by electrostatic deposition, and sintering the third polymer layer at >40°C, at 1.03 MPa (150 psi) pressurization, and with gaseous 1,1,1,2,3,3-hexafluoropropane, wherein the crystalline form sirolimus particles in the first agent layer and second agent layer remain in crystalline form throughout all steps in the method. mounting a stent on a holder in a coating chamber that imparts a charge to the stent, providing a first cloud of charged particles of polymer to the stents by rapidly expanding a pressurized solution of the polymer in densified 1,1,1,2,3,3-hexafluoropropane through a first orifice, wherein the polymer comprises PLGA, wherein a first polymer layer of the polymer particles is formed on the stent by electrostatic deposition, sintering the first polymer layer at >40°C in ambient pressure, providing a first cloud of charged sirolimus particles to the stents having an opposite charge than the charge of the stent by pulsing sirolimus particles into the chamber using a propellant in order to deposit a first agent layer on the stent, wherein at least a portion of the sirolimus particles is in crystalline form, providing a second cloud of charged particles of the polymer and a third cloud of charged particles of the polymer to the stents by sequentially rapidly expanding the pressurized solution through the first orifice, wherein the particles have an opposite charge than the charge of the stent, wherein a second polymer layer of the polymer particles is formed on the stent by electrostatic deposition, sintering the second polymer layer at >40°C in ambient pressure, providing a second cloud of charged sirolimus particles to the stents having an opposite charge than the charge of the stent by pulsing the sirolimus particles into the chamber using a propellant in order to deposit a second agent layer on the stent, wherein at least a portion of the sirolimus particles is in crystalline form, providing a fourth cloud of charged particles of the polymer, a fifth cloud of charged particles of the polymer, and a sixth cloud of charged particles of the polymer to the stents by sequentially rapidly expanding a pressurized solution through the first orifice, wherein the particles have an opposite charge than the charge of the stent, wherein a third polymer layer of the polymer particles is formed on the stent by electrostatic deposition, and sintering the third polymer layer at >40°C, at 1.03 MPa (150 psi) pressurization, and with gaseous 1,1,1,2,3,3-hexafluoropropane, wherein the crystalline form sirolimus particles in the first agent layer and second agent layer remain in crystalline form throughout all steps in the method.
