According to an aspect of the present invention, there is provided a light radiating probe which is flexible and uniformly radiates light emitted from a light scattering and radiating portion at all azimuth angles of 360 so as to enable the simultaneous radiation of light to cancers disposed at a plurality of places scattered in a wide region. The light radiating probe for photodynamic therapy according to the present invention includes an optical fiber which extends in an axial direction and through which light from a light source propagates, in which the optical fiber has a light guide portion which is formed by forming thin film cladding on a side surface of a flexible core, and a light scattering and radiating portion which is configured to scatter, with uniform intensity, light propagating through the light guide portion to a periphery of the light scattering and radiating portion in all azimuth angles with respect to an axial direction of the flexible core.

A light-emitting diode (LED) therapy device and method of use is provided that increases healing of tissues by targeting damaged tissue at a predetermined wavelength and pulsed at a predetermined frequency. The device includes a housing and a light radiation module enclosed within the housing. The light radiation module includes an LED, a controller unit connected to the LED to control wavelength and pulsed frequency of the LED, and a rechargeable power source. The device also includes a light-diffusing member connected to the housing designed to diffuse light emitted from the LED to damaged tissue in a human cavity. Light in the red or near infrared range and pulsed at a Nogier frequency increases the effectiveness of the LED device to stimulate healing of damaged tissues. Particular devices include incorporation into a pacifier for healing an infant's gums, or nasal, auditory, vaginal, or anal cavities and adults or children.

A process for preventing or treating myopia includes applying a pulsed energy, such as a pulsed laser beam, to tissue of an eye having myopia or a risk of having myopia. The source of pulsed energy has energy parameters including wavelength or frequency, duty cycle and pulse train duration, which are selected so as to raise an eye tissue temperature up to eleven degrees Celsius to achieve therapeutic or prophylactic effect, such as stimulating heat shock protein activation in the eye tissue. The average temperature rise of the eye tissue over several minutes is maintained at or below a predetermined level so as not to permanently damage the eye tissue.

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.

A laminated laser window having an inner layer transparent to light having wavelengths between 3.5 micrometers and 12 micrometers and having as an outer surface a nanometric-thick outer layer of SiO2. The window allows the passage of light within this wavelength range, for example from a CO2 laser. In The SiO2 outer layer maintains biocompatibility when used in laser devices for insertion into externally accessible bodily cavities.

The disclosed technology relates to a system for delivering UV-A/B light with a catheter to treat infectious or inflammatory disorders in a patient. While UV light in the UV-C range has traditionally been used to treat skin disorders and for focused ablation of plaques in the arteries and other targeted internal uses, it has not been developed for broader infection, inflammation or neoplasia treatment inside the human body. Here, the inventor(s) developed a system for emission of therapeutic doses of UV light via a catheter, capsule, endoscope, tube or port that can be used to manage internal infections and inflammatory conditions inside a patient

Mitochondrial antiviral signaling (MA VS) protein mediates innate antiviral responses, and is an important component of the response to severe acute respiratory syndrome coronavirus-2 (SARS-COV-2). Herein methods are provided to increase expression of mitochondrial antiviral signaling (MAVS) protein in epithelial cells by use of a UVA therapy to expose the epithelial cells to the UVA therapy, or to contact a first set of epithelial cells with a second set of epithelial cells which have been exposed to the UVA therapy, or to contact a first set of epithelial cells with the cell lysates of the second set of epithelial cells that have been exposed to the UVA therapy.

The present invention offers an alternative for cancer treatment where radiation, thermotherapy, or another therapeutic modality must be delivered to an internal cavity of a subject, for example to treat mouth, anal, cervical, and vaginal cancers. The invention is a new approach that builds on recent results in 3D printing and steerable needle motion planning to create customized implants containing customized curvature-constrained internal channels that fit securely, minimize air gaps, and precisely guide treatment sources through internal printed channels to accurately reach tumors and minimize damage to healthy tissue.
