  • Systems and methods for reducing the proliferation of microorganisms
    Patent number: 8838228
    Abstract: Systems and methods are provided that reduce the likelihood of infection caused by microorganisms. In general, microorganism population control can be achieved by exposing the population to an effective dose of electromagnetic radiation sufficient to cause a reduction in proliferation of the microorganism, wherein the electromagnetic radiation has a center wavelength between about 385 nm and about 425 nm. In preferred embodiments, the systems and methods described herein can be embodied in catheterization systems.
    Type: Grant

  • Rotary shutter
    Patent number: 5539488
    Abstract: A rotary shutter for controlling an optical path and including a rotating disk having an opening. A sensor monitor is representative of disk rotation, while a blocking element is selectively positioned within and without the optical path dependent upon the angular position of the disk and the desire to expose the light sensitive medium.
