medical devices , and in particular implantable medical devices , may be coated to minimize or substantially eliminate a biological organism &# 39 ; 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 . an aqueous latex polymeric emulsion is utilized to coat any medical device to a desired thickness by allowing for successive dipping and drying cycles . in addition , aqueous latex polymeric emulsions pose less of a chance of the bridging phenomenon associated with organic solvent based polymers .
