  • Patent number: 9067059
    Abstract: A light delivery device comprising an optical fiber having a non-feature portion and a feature portion having features that force light to couple out radially from the feature portion and provide a desired radial light output pattern. A method of photodisinfection of a cavity comprising of providing this device, apply a photosensitizing composition to treatment site within the cavity, and inserting at least a portion of the device into the cavity; and applying light delivered by the device from a light source to the treatment site within the cavity at a wavelength absorbed by the photosensitizing composition so as to inhibit or eliminate microbes located at the treatment site. The present invention also includes a method of making the device and a treatment kit containing the device and a container containing a photosensitizing composition.

  • Patent number: 8636727
    Abstract: The present disclosure relates to a portable irradiating arrangement having a light source, particularly a laser diode, comprising an outer sleeve, an inner sleeve, and a radiation distributing probe, whereby the inner sleeve is mounted in the outer sleeve and the radiation distributing probe may be attached at a probe-facing end of the outer sleeve, whereby the irradiating arrangement is designed in such a way that the light source can be turned on only when the radiation distributing probe is attached to the outer sleeve. The invention relates further to a portable irradiating arrangement, in which the inner sleeve is in contact with the radiation distributing probe in such a way that the inner sleeve must be detached from the radiation distributing probe before removal of the radiation distributing probe from the outer sleeve.
