Abstract
The invention provides a medical device which comprises a polymer coating. The polymer coating comprises a polymer comprising a polymer backbone and having at least two pendant groups selected from: (a) a polyoxyalkylene ether group, (b) a sulphate group, (c) a sulphonate group, or (d) a sulphamate group, and the polymer is produced by polymerizing monomers having such groups.
