Abstract
System and method for coating an expandable member of a medical device comprising a support structure to support the expandable member and an applicator positioned with at least one outlet proximate a surface of an expandable member. A drive assembly establishes relative movement between the at least one outlet and the surface of the expandable member to apply fluid on the surface of the expandable member along a coating path. A positioning device maintains a substantially fixed distance between the at least one outlet and the surface of the expandable member during relative movement therebetween by ejecting a pressurized medium against the surface of the expandable member.
