Abstract
A medical device having a bio-active coating is prepared by providing a polymeric substrate having hydroxyl and/or amine functionality on a surface thereof and applying the bio-active coating to the surface. The bio-active coating is the reaction product of two different reactions. The first reaction includes reacting the polymeric substrate with a hydrophilic, isocyanate-terminated spacer having at least one isocyanate group at its first and second ends. The second reaction includes reacting a remaining, unreacted isocyanate-terminated end of the spacer with a bio-active agent to bond the bio-active agent to the spacer.
