Medical devices, and in particular implantable medical devices such as stents and stent delivery systems including catheters, may be coated to minimize or substantially eliminate a biological organisms reaction to the introduction of the medical device to the organism or to treat a particular condition. A dip coating process is utilized to minimize waste and to customize coating thickness and drug loading directly at the clinical site just prior to therapeutic use on a patient. An aqueous latex polymeric emulsion is utilized to coat any medical device to a desired thickness by allowing for successive dipping and drying cycles at the clinical site. In addition, aqueous latex polymeric emulsions pose less of a chance of the bridging phenomenon associated with organic solvent based polymers.
