Abstract

Abstract The present invention includes biocompatible coatings and films for use on implantable medical devices and medical devices containing such coatings and films applied to a surface thereof, which coatings/films are present on the device in an amount effective to provide an inert surface to be in contact with body tissue of a mammal upon implantation of the device in the mammal, and contain a film-forming polyfluoro copolymer prepared from an amount of a monomer selected from the group consisting of vinylidenefluoride and tetrafluoroethylene, and an amount of a second monomer other than the first monomer, wherein the amounts of the first and second monomers are effective to provide the coating and films with properties effective for use in coating implantable medical devices when the coated device is subjected to a maximum temperature of less than about 100°C.
