Patents by Inventor Douglas Philip HANSON

Douglas Philip HANSON 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).

  • Amine-functionalized polymeric compositions for medical devices
    Patent number: 10688217
    Abstract: The present disclosure provides amine-modified polymer foams, which may be used for wound dressing materials. For example, the modified materials can include a covalently attached molecule comprising free amine groups. Such amine groups can be used, for instance, to conjugate biologically active polypeptides and/or linkers. Methods for using modified polymers are also provided.
    Type: Grant

  • Composition For Enzymatic Debridement
    Publication number: 20190008927
    Abstract: Methods and compositions for the enzymatic debridement of wounds are provided. Methods for preparing enzymatic debridement compositions are also provided. In one embodiment, an enzymatic debridement composition prepared by dissolving crude bromelain in a composition comprising a weak acid, and filtering and/or dialyzing the dissolved crude bromelain to obtain the enzymatic debridement composition is provided.

  • Sulfhydryl-functionalized polymeric compositions for medical devices
    Patent number: 10053532
    Abstract: The present disclosure provides sulfhydryl-modified polymer foams, which may be used for wound dressing materials. For example, the modified materials can include free sulfhydryl group, which can serve as a linker to attach biologically active molecules. For example, sulfhydryl groups can be used to conjugate biologically active polypeptides and/or metals to foam polymers. Methods for using sulfhydryl-modified polymers, such as for wound dressings, are also provided.
