Patents by Inventor Erica M. Tenbroek

Erica M. Tenbroek 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).

  • Protective gel based on chitosan and oxidized polysaccharide
    Patent number: 9433636
    Abstract: Bodily tissue and structures may be protected using a fluid layer containing a mixture of chitosan and oxidized polysaccharide. The mixture forms a protective gel layer via in situ crosslinking. Compared to crosslinking using a low molecular weight aldehyde such as glutaraldehyde or genipin, oxidized polysaccharides appear to provide faster gelation while avoiding the use of potentially less bioacceptable low molecular weight aldehydes.
    Type: Grant
    Filed: April 23, 2009
    Date of Patent: September 6, 2016
    Assignee: Medtronic, Inc.
    Inventors: Edze Jan Tijsma, Maria Nieves Gonzalez, Erica M. TenBroek, Nancy Schaffhausen
