Nancy J. Rustad has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Hydrophilic pressure sensitive adhesives
    Patent number: 5660178
    Abstract: A hydrophilic, pressure sensitive adhesive of a poly(ethylene oxide) derived network plasticized with an essentially non-volatile, polar plasticizer present in an amount sufficient to form a cohesive, pressure sensitive adhesive. The polymeric network is prepared from an oligomeric precursor comprising difunctional poly(ethylene glycol) moieties which have been end-capped with ethylenically unsaturation. The adhesive is useful as a biomedical adhesive for transmitting or receiving electrical signals as a component of a biomedical electrode. The adhesive is also useful as a drug delivery device to deliver pharmaceuticals or other active ingredients to or through mammalian skin. The adhesive is also useful as a component in a skin covering for protecting mammalian skin or mammalian skin openings with antimicrobial agents. A method of preparation of the adhesive is also disclosed.
    Type: Grant
    Filed: January 5, 1996
    Date of Patent: August 26, 1997
    Assignee: Minnesota Mining and Manufacturing Company
