  • Apparatus, and systems for processing and treating a biological fluid with light
    Patent number: 7459695
    Abstract: Apparatus, systems and methods are disclosed for treating a biological fluid with light. A container of biological fluid is introduced into a fluid treatment chamber where it is contacted with light provided by one or more light sources in proximity to the fluid treatment chamber. A drawer for holding containers of biological fluid introduces the containers into the chamber. Containers for holding the biological fluid are marked by the apparatus to indicate the status of the treatment.
    Type: Grant
    Filed: July 27, 2005
    Date of Patent: December 2, 2008
    Assignees: Fenwal, Inc., Cerus Corporation

  • Electronic stethoscope
    Publication number: 20030072457
    Abstract: An electronic stethoscope having several modes of operation to process acoustic signals to provide filtered signals useful for diagnosis. In one mode of operation the stethoscope substantially provides only acoustic signals generated by biological activity of the heart. In another mode of operation, the acoustic stethoscope substantially provides only acoustic signals generated by biological activity of the lungs. In another mode of operation, the electronic stethoscope disproportionately amplifies abnormal heart sounds and normal heart sounds to enhance diagnosis of heart abnormalities. The electronic stethoscope is operated in a manner similar to a conventional acoustic stethoscope and has similar spectral characteristics, thus allowing a user with acoustic stethoscope experience to easily use the electronic stethoscope.

  • Methods and apparatus for inactivating contaminants in biological fluid
    Patent number: 6190609
    Abstract: Apparatus and methods for treating a biological fluid with light and for inactivating contaminants in biological fluid. The biological fluid is contacted with a light source providing a high intensity light to the biological fluid. The biological fluid may include a quantity of a photochemical agent that when activated by light is operable to cause inactivation of at least some of the contaminants.
