Patents by Inventor Maria Nieves Gonzalez

Maria Nieves Gonzalez 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

  • Chitosan-containing protective composition
    Patent number: 8530632
    Abstract: Body tissue and structures may be protected using a fluid containing a mixture of partially crosslinked polysaccharide and a further crosslinker. The mixture desirably is sprayable, forms a fluid protective layer via in situ crosslinking, desirably does not drip or run from a treatment site, and may avoid the use of more rapidly curing but potentially less bioacceptable crosslinkers at the treatment site.

  • Solvating system and sealant for medical use in the sinuses and nasal passages
    Patent number: 7993675
    Abstract: Chronic rhinosinusitis and other bacterial sinus conditions may be treated by applying a solvating system containing a surfactant to a bacterial biofilm in a nasal or sinus cavity, disrupting the biofilm, and applying a protective layer of a polymeric film-forming medical sealant.

  • THIOLATED CHITOSAN GEL
    Publication number: 20090269417
    Abstract: Bodily tissue and structures may be coated with a protective gel layer made from a two-part composition whose first part contains thiolated chitosan and whose second part contains sufficient oxidizing agent or external crosslinking agent so that when the two parts are mixed and coated onto the tissue or structure the mixture will form a protective gel layer in less than 30 minutes.
