Patents by Inventor Kevin Diehn

Kevin Diehn 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).

  • Patent number: 10908031
    Abstract: The present invention relates to a device for evidencing when a stimulus sensitive product has been exposed to a predetermined stimulus, and the invention further may include a method for manufacturing aspects of that device.
    Type: Grant

    Date of Patent: February 2, 2021
    Inventors: Joseph C. White, Kevin Diehn, Bani H. Cipriano, Rel S. Ambrozy
  • Patent number: 10493094
    Abstract: A hemostatic putty for treatment of a variety of wounds topographies, including but not limited to highly three dimensional wounds, for example gunshot wounds and impalements, is disclosed. The putty is comprised of a matrix polymer weakly crosslinked or not crosslinked such that a viscoelastic matrix is formed. The viscoelastic nature of the putty is tunable by the composition and enables the putty to conform to a variety of wound topographies. Likewise, a hemostatic polymer, for example chitosan or hydrophobically modified chitosan, is included in this matrix to impart hemostatic properties and tissue adhesive on the putty. The hemostatic polymers disclosed prevent microbial infection and are suitable for oxygen transfer required during normal wound metabolism.

  • Patent number: 10334897
    Abstract: A formulation for coating surfaces, for example gloves, with a tacky film comprises a hydrophobically modified biopolymer, where the hydrophobic modifications of the biopolymer correspond to between 1 and 90% of available functional groups, a plasticizer, and a volatile solvent. The formulation quickly dries into a tacky film that provides an enhanced friction of the surface.
