Methods and related devices for impinging light on tissue, for example within a body 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, stimulating enzymatic generation of nitric oxide to increase endogenous stores of nitric oxide, releasing nitric oxide from endogenous stores of nitric oxide, 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 and methods for light treatments are disclosed that provide light doses for inducing biological effects on various targeted pathogens and targeted tissues with increased efficacy and reduced cytotoxicity.

Phototherapeutic light for treatment of pathogens

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. Illumination devices may be configured to communicate with networks and/or servers to provide control and/or management of phototherapy treatments.

Illumination devices for inducing biological effects

Systems and methods for phototherapeutic modulation of nitric oxide in mammalian tissue include use of a first wavelength and first radiant flux of light to stimulate enzymatic generation of nitric oxide, and use of a second wavelength and second radiant flux of light to stimulate release of nitric oxide from endogenous stores of nitric oxide. Pulsed light and/or partially non-overlapping light impingement windows may be used. Non-coherent light impinged on tissue may include a peak wavelength in a range of from 410 nm to 440 nm in the absence of light emissions having a peak wavelength of from 600 nm to 900 nm.

Systems and methods for phototherapeutic modulation of nitric oxide

The present invention relates generally to topical antiviral compositions, delivery systems, and methods of using the same.

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. Biological effects may include upregulating and downregulating inflammatory immune response molecules within a target tissue. 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.

Devices and methods for impinging light on tissue to induce one or more biological effects, and more particularly enhanced testing and characterization techniques for phototherapeutic light treatments are disclosed. Such testing and characterization techniques may be particularly useful in the evaluation and development of light-based treatments for various infectious diseases, including multiple variants of SARS-CoV-2. In particular aspects, testing and characterization techniques are related to the direct testing of differentiated tissue models of human airway epithelia that have been exposed to various pathogens. Phototherapeutic light treatments and corresponding treatment protocols for light are also described that not only inactivate SARS-COV-2 variants in cell-free suspensions, but also inhibit SARS-CoV-2 infections at multiple stages of infection in tissue models of human airway epithelia in a variant-agnostic manner.

Enhanced testing and characterization techniques for phototherapeutic light treatments

Devices and related methods for impinging light on tissue to induce one or more biological effects, and more particularly illumination devices and related methods for phototherapeutic light treatments in the presence of vitamins are disclosed. Biological effects may include at least one of inactivating and inhibiting growth of one or more combinations of microorganisms and pathogens, including but not limited to viruses. Phototherapeutic light treatments in the presence of vitamins may involve providing one or more vitamins in the form of a coating or film on a surface of a target tissue and irradiating the target tissue with light. By performing the phototherapeutic light treatment in the presence of vitamins, efficacy of the light treatment may be improved, thereby reducing viral loads and/or reducing doses of light received by the target tissue.

Particular illumination devices are disclosed that provide safe and effective treatments for upper respiratory tract infections, including coronaviridae and orthomyxoviridae.
