Patent attributes
The invention provides fluorinated polymeric articles formed a composition including a fluoropolymer. The fluoropolymer is formed using a fluorinated monomer that provides the fluoropolymer with most or all of the fluorine atoms not directly covalently attached to an atom of the fluoropolymer backbone. The fluoropolymer can also include a non-fluorinated hydrophilic monomer in a weight amount greater than the fluorinated monomer. The fluoropolymer composition also includes an ultraviolet light (UV)-reactive group capable of covalent bonding to promotes formation of the fluorinated polymeric article. The fluorinated polymeric article can be in the form of a durable lubricious coating on the surface of an implantable medical device. Coatings of the invention exhibit excellent wet/dry lubricity, durability, and controlled swelling.
