  • Reduction of contaminants in blood and blood products using photosensitizers and peak wavelengths of light
    Patent number: 9044523
    Abstract: Methods and apparatuses are provided for reduction of pathogens in fluids containing blood products. Preferred methods include the steps of adding an effective, non-toxic amount of a photosensitizer such as riboflavin to the blood product and exposing the fluid to light having a peak wavelength.
    Type: Grant
    Filed: August 17, 2007
    Date of Patent: June 2, 2015
    Assignee: TERUMO BCT, INC.
    Inventors: Dennis J. Hlavinka, Raymond P. Goodrich, Heather Reddy

  • Inactivation of West Nile virus and malaria using photosensitizers
    Patent number: 7049110
    Abstract: Methods and apparatuses are provided for inactivation of microorganisms in fluids or on surfaces. Preferably the fluids contain blood or blood products and comprise biologically active proteins. Preferred methods include the steps of adding an effective, non-toxic amount of a photosensitizer to a fluid and exposing the fluid to photoradiation sufficient to activate the photosensitizer whereby microorganisms are inactivated.

  • Method and apparatus for inactivation of biological contaminants using photosensitizers
    Publication number: 20030073650
    Abstract: Methods and apparatuses are provided for inactivation of microorganisms in fluids or on surfaces. Preferably the fluids contain blood or blood products and comprise biologically active proteins. Preferred methods for inactivation of microorganisms include the steps of adding an effective, non-toxic amount of an endogenous photosensitizer and a quencher to a fluid and exposing the fluid to photoradiation sufficient to active the endogenous photosensitizer whereby microorganisms are inactivated. The quencher reduces side reactions generated by a photosensitizer and light that can damage desired biological components.
