The invention relates to a positioning apparatus (100) for positioning a light-guiding fiber (206) in a calibration port (208) of a medical apparatus (202) comprising at least one light source (204) for the light-guiding fiber (206), wherein the positioning apparatus (100) comprises an elongate body (102) with two end faces (110, 112) and at least one side face (116). A channel (104) for receiving the light-guiding fiber (206) is formed in the body (102), said channel extending along a longitudinal axis of the body (102) proceeding from a first end face (110). Here, according to the invention, provision is made for the body (102), at least in one portion, to consist of an opaque material in the region of the channel (104) and/or to be coated with an opaque material and for said body to have at least one cutout (113, 118), which extends from a side face (116) and/or the second end face (112) of the body (102) to the channel (104) such that radiation emitted by the light-guiding fiber (206) can only emerge from the positioning apparatus (100) in unimpeded fashion through the at least one cutout (113, 118).

Methods of treating skin disorders are disclosed. The methods involve impinging light having a first peak wavelength on the tissue at a first radiant flux, wherein the first peak wavelength and the first radiant flux is selected to provide an anti-inflammatory effect, and impinging light having a second peak wavelength on the tissue at a second radiant flux, wherein the second peak wavelength and the second radiant flux are selected to either stimulate enzymatic generation of nitric oxide to increase endogenous stores of nitric oxide or release nitric oxide from the endogenous stores are disclosed. Representative skin disorders include pruritus, psoriasis, acne, rosacea, and eczema, and the skin can include the scalp. The methods can reduce stinging and/or itching associated with the skin disorder. The anti-inflammatory wavelengths can be in the range of between about 650 and about 680 nm.

A phototherapy device (100) and a phototherapy instrument (500), comprising a near infrared irradiation module (110) used for emitting near infrared light to the head, and a control component (120) used for controlling the operation of the near infrared irradiation module (110) and coupled to the near infrared irradiation module (110). A method for using near infrared light for therapy, which comprises applying a first, optional second, optional third or more near infrared lights to the head of a patient. The device and method are used for treating Alzheimer's disease, improving brain mitochondrial function and ATP levels, promoting amyloid beta protein (Aβ) decomposition, reducing Aβ deposition, reducing damage to nerve cells, improving nerve tissue repair and regeneration capabilities, improving cognitive ability etc. A therapy method using the phototherapy device (100) or the phototherapy instrument (500), and a computer readable recording medium controlling required near infrared light.

This present invention and its embodiments relates to methods for reducing pain during photodynamic therapy of actinic keratosis. The present invention also relates to methods of treating actinic keratosis with reduced pain during photodynamic therapy of actinic keratosis.

A method is provided for performing electromagnetic radiation therapy on a subject. The method comprises providing a device which emits electromagnetic radiation, wherein the electromagnetic radiation includes a first portion that oscillates between at least first and second distinct states, and a second non-oscillatory portion; and illuminating the subject with the electromagnetic radiation.

Exemplary embodiments described herein provide systems and methods for administer multiple stimulus to a patient in order to improve the efficacy of the administered stimulus on the brain activity of the patient. Exemplary embodiments described herein may combined magnetic stimulation along with sensory stimulation to influence the intrinsic frequency of an EEG band of a person.

A facial skin disorder (FSD) identification system is provided and includes a sliding rail arranged around a human facial epidermis, a carrier arranged on the sliding rail, at least one image capturing device arranged on the carrier, and a control circuit unit arranged on the carrier for the carrier to move on the sliding rail and the image capturing device to capture images of the human facial epidermis.

The present disclosure relates to systems, methods, and uses of systems for treating a skin condition with phototherapy. A system comprises (a) a phototherapy device comprising a phototherapy light source; (b) a patient computing device comprising a processor and a memory, the patient computing device configured to: transmit a first signal to the phototherapy device enabling operation of the phototherapy device according to one or more conditional prescription parameters, activate the phototherapy light source, and transmit a second signal reporting operation of the phototherapy device; and (c) a server configured to communicate with the patient computing device and receive the second signal.

A device and method for therapeutically treating conditions using electromagnetic radiation (EMR) is described herein. EMR, of optimal wavelengths and at surprisingly low energy levels, are pulsed for a time duration when aimed at an area of interest, the outcome being an improvement in the condition while not doing damage to surrounding tissue.

A device to stimulate the retina comprises one or more light sources coupled to one or more optical elements. The one or more optical elements is configured to illuminate the retina with one or more images at a location away from a fovea of a wearer. In some embodiments, each of the one or more images comprises a depth of focus and a spatial resolution. The one or more images can be formed at a distance anterior to the retina, at a distance posterior to the retina or on the retina. In some embodiments, the depth of focus is less than the distance, and the spatial resolution greater than a spatial resolution of the retina at the location.
