PROBLEM TO BE SOLVED: To provide stent coatings having the advantage that although coated stents improve pharmacological treatment of a patient and improve biocompatibility of a medical device in the patient, coatings can still be improved, and in particular, it is desirable to have biologically beneficial (biobeneficial) stent coatings that are creep compliant and are capable of providing modulated drug release rate by increased water absorption in the overall coating.SOLUTION: A composition is disclosed which comprises: a structural component comprising linear acrylic homopolymers or linear acrylic copolymers; and a biobeneficial component comprising copolymers having an acrylate moiety and a biobeneficial moiety. |
