A treatment method and a treatment system for irradiating the antibody-photosensitive substance bound to the tumor cell membrane in the tumor cell with the near-infrared ray includes: intravenously administering the antibody-photosensitive substance; inserting an endoscope from a mouth, a nose, or an anal and allowing the endoscope to reach a vicinity of a tumor; making a tubular elongated tube, in which a lumen is formed, protrude from the endoscope; bringing the elongated tube into contact with the tumor while checking an image obtained by the endoscope; allowing an optical fiber inserted into the lumen of the elongated tube to reach an inside or the vicinity of the tumor; and irradiating the antibody-photosensitive substance bound to the tumor cell membrane with the near-infrared ray from the optical fiber after 12 hours to 36 hours from the intravenous administration.

A treatment method and a treatment system capable of effectively irradiating an antibody-photosensitive substance bound to a tumor cell with a near-infrared ray. The treatment method for irradiating the antibody-photosensitive substance bound to the tumor cell membrane in the tumor cell with the near-infrared ray includes: intravenously administering the antibody-photosensitive substance; percutaneously puncturing a tumor or a vicinity of the tumor with a hollow outer needle, while percutaneously acquiring and checking an ultrasound image; making an inner needle having a plurality of sharp inner needle tips protrude from the outer needle, and puncturing the tumor or the vicinity of the tumor with the inner needle tips; and irradiating the antibody-photosensitive substance bound to the tumor cell membrane with the near-infrared ray from an optical fiber inserted into the inner needle after 12 hours to 36 hours from the intravenous administration.

Illumination devices for impinging light on tissue, for example within a body cavity of a patient, to induce various biological effects are disclosed. Biological effects may include at least one of inactivating and/or inhibiting growth of one or more pathogens, upregulating a local immune response, increasing endogenous stores of nitric oxide, releasing nitric oxide from endogenous stores, and inducing an anti-inflammatory effect. Wavelengths of light are selected based on intended biological effects for one or more of targeted tissue types and targeted pathogens. Light treatments may provide multiple pathogenic biological effects, either with light of a single wavelength or with light having multiple wavelengths. Devices for light treatments are disclosed that provide light doses for inducing biological effects on various targeted pathogens and tissues with increased efficacy and reduced cytotoxicity. Particular illumination devices are disclosed that provide safe and effective treatments for upper respiratory tract infections, including coronaviridae and orthomyxoviridae.

Modulation of foreign body responses in living tissue, and more particularly, devices and related methods for light-based modulation of foreign body responses in living tissue are disclosed. Light sources are disclosed that provide light with characteristics for modulation of foreign body responses that may be elicited by percutaneous and/or subcutaneous devices, including medical devices and other consumer electronic devices. Light delivery structures are disclosed that propagate light from the light sources to irradiate associated subcutaneous tissues. Modulation of foreign body responses may include inhibiting collagen and fibrous tissue generation, modulating inflammation and healing, and/or increasing nitric oxide production and/or release. By modulating foreign body responses associated with percutaneous and/or subcutaneous devices, performance characteristics and lifetimes of such devices may be improved.

An ocular light therapy arrangement for treating a user having a neurologic disorder includes a light emitting device the emits a light having a flicker rate of less than or equal to about 2 Hz and/or greater than or equal to about 85,000 Hz at a wavelength of within a first range of from about 500 nm to about 565 nm, wherein the light is effective to reduce neurologic disorder symptoms by reducing stimulation of the user's retina and brain cortex.
