Patents by Inventor Kenrick Kuwahara

Kenrick Kuwahara 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: 9393267
    Abstract: The present invention discloses methods and compositions comprising a biocompatible gel that is used in tissue repair and regeneration. Once the gel is administered to a tissue site in need of repair or regeneration, the cells migrate from the gel into the tissue and repair or regenerate the tissue.
    Type: Grant
    Filed: February 19, 2010
    Date of Patent: July 19, 2016
    Assignee: University of Southern California
    Inventors: Bo Han, Kenrick Kuwahara
  • Publication number: 20160000602
    Abstract: Embodiments of an implantable device for delivering a therapeutic agent to a patient include a reservoir configured to contain a liquid comprising the therapeutic agent, and a cannula in fluid communication with the reservoir. When a predetermined cracking pressure is reached, a valve opens and allows the liquid to flow through the cannula.

  • Publication number: 20130202564
    Abstract: This invention provides a composition for controlled-release of polypeptide growth factors useful in tissue repair or engineering. The composition include a polypeptide growth factor covalently cross-linked to a biocompatible substrate by a transgultaminase. The cross-linking tethers the growth factor to a substrate so that it will not diffuse away from the desired site of application. It also concomitantly inactivates the growth factor. Release and reactivation of the growth factor can be achieved by endogenously produced metalloproteinase (MMPs) or exogenously provided proteases such as collagenases.

  • Publication number: 20110144619
    Abstract: Embodiments of an implantable device for delivering a therapeutic agent to a patient include a reservoir configured to contain a liquid comprising the therapeutic agent, and a cannula in fluid communication with the reservoir. A valve for maintaining a constant flow rate through the cannula independent of the pressure applied to the device may be included.

  • Publication number: 20080039792
    Abstract: An implantable device for delivering a therapeutic agent to a patient is provided. The device includes a reservoir configured to contain a liquid comprising the therapeutic agent. The device further includes a cannula in fluid communication with the reservoir. The cannula has an outlet configured to be in fluid communication with the patient. The device further includes a first electrode and a second electrode, at least one of the first electrode and the second electrode is planar. The device further includes a material in electrical communication with the first and second electrodes. A voltage applied between the first electrode and the second electrode produces gas from the material, the gas forcing the liquid to flow from the reservoir to the outlet.
