Patents by Inventor Benjamin J. Wiley

Benjamin J. Wiley 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).

  • Synthetic hydrogel composite
    Patent number: 12064533
    Abstract: Cellulose-reinforced hydrogels may include a cellulose nanofiber network and an interstitial hydrogel portion within interstitial regions of the cellulose nanofiber network, the interstitial hydrogel portion comprising polyvinyl alcohol (PVA), wherein the hydrogel component has a crystallinity of 20% or greater.
    Type: Grant
    Filed: May 26, 2023
    Date of Patent: August 20, 2024
    Assignee: Duke University
    Inventors: Benjamin J. Wiley, Huayu Tong, Jiacheng Zhao
  • Nanofiber reinforcement of attached hydrogels
    Patent number: 11707555
    Abstract: Described herein are hydrogels attached to a base with the strength and fatigue comparable to that of cartilage on bone and methods of forming them. The methods and apparatuses described herein may achieve an attachment strength between a hydrogel and a substrate equivalent to the osteochondral junction. In some examples the hydrogel may be a triple-network hydrogel (such as BC-PVA-PAMPS) that is attached to a porous substrate (e.g., a titanium base) with the shear strength and fatigue strength equivalent to that of the osteochondral junction.
