Fluoropolymer coatings and related methods

A coating for a medical device or appliance may include a fluoropolymer and a polyimide. Such coatings may provide a lubricious exterior surface that facilitates insertion or displacement of a medical device in a body lumen. Some coatings that include a fluoropolymer and a polyimide may, among other functions and characteristics, provide increased strength and/or durability relative to some other coatings.
