Abstract
Self-crosslinking hydrophilic coatings and methods of forming the same are disclosed. The lubricious hydrophilic coatings may be formed on the surfaces of medical devices. The self-crosslinking hydrophilic coating formulations form a hydrophilic coating when the solvent of the hydrophilic coating formulation is dried off, or otherwise removed, from the formulation.
