Claim:
A method of delivering a taxane therapeutic agent to a body vessel of a patient comprising: inserting a coated implantable device into the body vessel, wherein the coated implantable device comprises at least one surface having a coating comprising the taxane therapeutic agent in a first taxane solid form characterized by a vibrational spectrum comprising at least two peaks between 1735 and 1705 cm −1 and a solubility of less than 20% wt. after 24 hours in porcine serum at 37° C., and in a second taxane solid form characterized by a vibrational spectrum comprising one peak between 1735 and 1705 cm −1 and a solubility of greater than 50% wt. after 24 hours in porcine serum at 37° C., wherein at least 10% of the taxane therapeutic agent is present in the first taxane solid form positioning the coated implantable device within the body vessel; and radially expanding the coated implantable device within the body vessel so as to place the coated implantable device in contact with a portion of a wall of the body vessel in a manner effective to deliver at least a portion of the taxane therapeutic agent to the wall of the body vessel.
