  • Biocompatible materials
    Patent number: 5711959
    Abstract: A biocompatible material comprising a substrate and a phospholipid moiety covalently attached thereto in an amount and orientation effective to provide an improved nonthrombogenic surface relative to the substrate without the phospholipid moiety covalently attached thereto is provided. In particularly preferred embodiments, the biocompatible material has the following structure: ##STR1## wherein: R.sup.1 is a (C.sub.1 -C.sub.30)alkyl group; R.sup.2 is a (C.sub.1 -C.sub.30)alkylene group; m is 1-4; n is 1-4; and L is a divalent linking group covalently bonded to the substrate and to the phospholipid moiety.
    Type: Grant
    Filed: September 10, 1996
    Date of Patent: January 27, 1998
    Assignee: Regents of the University of Minnesota
