  • MR-signal emitting coatings
    Patent number: 6896874
    Abstract: The present invention provides a coating that emits magnetic resonance signals and a method for coating medical devices therewith. The coating includes a paramagnetic metal ion-containing polymer complex that facilitates diagnostic and therapeutic techniques by readily visualizing medical devices coated with the complex. The present invention also provides methods by which pre-existing polymers and medical devices may be made MR-imageable. The invention also provides methods of improving MR-imageability of polymers and medical devices by encapsulating the polymers and medical devices with hydrogels.
    Type: Grant
    Filed: May 9, 2002
    Date of Patent: May 24, 2005
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: Junwei Li, Orhan Unal, Xiqun Jiang, Charles Milton Strother, Hyuk Yu

  • Biomembrane mimetic surface coatings
    Patent number: 6486334
    Abstract: Disclosed are thiol-functionalized phospholipids that have been covalently linked to a gold and/or silver substrate, methods for making them, and intermediates useful for such purposes. The resulting material creates a biomimetic surface that can be included in a conduit containing blood.
