Method for applying drug coating to a medical device in surgeon room

摘要

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 organism's 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.
