The present invention relates to a medical device for insertion into the body wherein the device has at least one surface which periodically comes into contact with a second surface. The first surface comprises an improved lubricious coating having a first hydrogel layer and a second hydrophobic top coating which prevents the hydrogel coating from prematurely absorbing too much moisture. The hydrophobic top coating comprises at least one hydrophilic surfactant which acts as a carrier to facilitate removal of the hydrophobic top coating upon entry into an aqueous environment.
