A medical device with a hydrophilic and lubricious coating, wherein the
coating includes a hydrophilic polymeric unit layer deposited on the
medical device and cross-linked with a plasma deposited double bond
monomer. The hydrophilic polymeric unit can include ethylene oxide with
one or more primary or secondary alcohol groups or glycosaminoglycans
such as hyaluronic acid, and the double bond monomer includes monomers
containing at least one double bond, preferably a C.dbd.C, C.dbd.N or
C.dbd.O bond, including N-trimethylsilyl-allylamine, ethylene, propylene
and allyl alcohol.
