  • Polymer coatings on medical devices
    Patent number: 8343212
    Abstract: 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.
    Type: Grant
    Filed: May 15, 2008
    Date of Patent: January 1, 2013
    Assignee: Biotectix, LLC
