Abstract
A method of providing a lubricious hydrophilic coating on an intracorporeal medical device and the coated device produced thereby, wherein the coating is durable and highly lubricious when in contact with body fluids. In one embodiment, the coating comprises a polymerized base coat and a hydrophilic top coat, where the base coat has a binding component which binds to the hydrophilic compound of the top coat, and a grafting component which binds to the binding component and to the device. In another embodiment, the coating comprises a blend of a hydrophilic compound, a grafting component, and salt, wherein the polymerized grafting component contains uncrosslinked domains. The hydrophilic coating of the invention can be applied to a medical device with a polymeric surface such as a polymeric catheter, or a metal device coated with a polymeric primer.
