  • Systems and methods for removing viral agents from blood
    Patent number: 7374870
    Abstract: Systems and methods treat plasma carrying contaminants and cellular matter that are capable of entraining contaminants. The systems and methods separate cellular matter from the plasma by filtration, thereby removing contaminants entrained within the cellular matter. The system and methods add to the plasma a photoactive material. The systems and methods emit radiation at a selected wavelength into the plasma to activate the photoactive material and thereby eradicate the contaminant that is free of entrainment by cellular matter.
    Type: Grant
    Filed: February 11, 2005
    Date of Patent: May 20, 2008
    Assignee: Fenwal, Inc.
    Inventors: Robert E. Herman, John Chapman, Chong-Son Sun, Jean M Mathias, Daniel F. Bischof

  • Systems and methods for removing free and entrained contaminants in plasma
    Patent number: 6695805
    Abstract: Systems and methods treat plasma carrying contaminants and leukocytes that are capable of entraining contaminants. The systems and methods separate leukocytes from the plasma by filtration, thereby removing contaminants entrained within leukocytes. The systems and methods also add to the plasma a photoactive material and emit radiation at a selected wavelength into the plasma to activate the photoactive material and thereby eradicate the contaminant that is free of entrainment by leukocytes.

  • Method for purifying blood plasma and apparatus suitable therefor
    Patent number: 6168718
    Abstract: A method for purifying conventionally treated blood plasma to remove substantially all residual leukocytes while maintaining useful flow rates for medically useful amounts of plasma utilizes a disposable, heat-sterilizable filter employing one or more depth-type prefilters and at least one intermediate hydrophilic microporous membrane followed by at least one final hydrophilic microporous membrane having a smaller pore size than the intermediate membrane within a common housing. The purified plasma is preferably subjected to chemical treatment to destroy infectious agents such as hepatitis and HIV.
