POLYMER COATINGS ON MEDICAL DEVICES

摘要

A medical device, for example a stent, has a surface which in use contacts body tissue, wherein said surface has on it a biocompatible coating layer comprising a polymer having covalently bound allyl-terminated pendent groups, said pendent groups comprising a moiety selected from -0-CH2—CH═CH2—S—CH2—CH═CH2—S(=0)-CH2—CH═CH2—Se—CH2—CH═CH2 and—Se (=0 J-CH2—CH═CH2. This surface has good biocompatibility and can bind strongly to a metallic surface. The polymer may be made from an electropolymerisable monomer, e.g. a pyrrole.
