A skin care device according to an embodiment of the present disclosure includes a substrate; a case for covering surface of the substrate; and at least one galvanic current application device electrically connected to the substrate, in which each of the at least one galvanic current application device includes a contact head that forms a contact surface with respect to a user's skin and is electrically connected to the substrate; and a holder provided between the substrate or the case and the contact head, and in which the holder includes an elastic fixing body elastically fixing the contact surface of the contact head to a position spaced apart from the case by a predetermined length.

A light beam irradiation planning apparatus according to embodiments includes processing circuitry configured to identify a tumor site included in a medical image, set an irradiation mode to the tumor site, the irradiation mode satisfying a criterion for a chemical reaction of a drug binding to a tumor by a light beam, and generate guidance information for guiding light beam irradiation by a light beam irradiation device based on the set irradiation mode.

An unattended approach can increase the reproducibility and safety of the treatment as the chance of over/under treating of a certain area is significantly decreased. On the other hand, unattended treatment of uneven or rugged areas can be challenging in terms of maintaining proper distance or contact with the treated tissue, mostly on areas which tend to differ from patient to patient (e.g. facial area). Delivering energy via a system of active elements embedded in a flexible pad adhesively attached to the skin offers a possible solution. The unattended approach may include delivering of multiple energies to enhance a visual appearance.

A treatment apparatus and a treatment method capable of effectively treating cancer including a cervix. The treatment apparatus includes: a main shaft including a distal portion and a proximal portion; an inflation portion disposed on a distal side of the main shaft and configured to be inflated by inflowing a fluid; a distal shaft protruding from the inflation portion toward the distal side; and at least one irradiation unit configured to emit excitation light of an antibody-photosensitive substance from the distal shaft and the inflation portion.

A device for the drying of tooth or bone surfaces includes a radiation source for irradiating the tooth or bone surface to be dried, a temperature sensor and/or a humidity sensor.

An optical stimulation system includes a light source; an optical lead coupled, or coupleable, to the light source; at least one of a calibration table or a calibration formula, generated by a calibration procedure specifically using the light source and the optical lead of the optical stimulation system; and a control unit coupled, or coupleable, to the light source. The control module includes a memory to store the at least one of the calibration table or the calibration formula, and a processor coupled to the memory and configured for receiving a target light output level, using the at least one of the calibration table or the calibration formula to determine at least one operational parameter for generating the target light output level, and directing the light source, using the at least one operational parameter, to generate light at the target light output level.

A medical device that includes a carrier member, one or more operative components disposed in the carrier member, an optical fiber at least partly disposed in the carrier member, and at least one fiber Bragg grating (FBG) sensor array associated with the optical fiber and disposed in the carrier member. The carrier member includes an insertion end and side walls that contact the subject's body during positioning of the carrier member in the subject's body. The at least one FBG sensor array measures contact forces at one or both of the insertion end and along the side walls of the carrier member during positioning of the carrier member in the subject's body. A multi-core optical fiber configured for use in a medical device for positioning in a subject's body is also provided. A system and method for guiding positioning of a medical device in a subject's body is also provided.

This disclosure pertains to a system configured to control light exposure for circadian phase management and/or light deficient disorders of a subject. The system comprises a user interface, physiological sensors configured to generate output signals conveying physiological data of the subject, and a light control valve configured to block or reduce blue light ambient radiation reaching eyes of the subject. Processors are in communication with the user interface, the physiological sensors, the light control valve, and radiation generators. The processors cause the system to receive physiological goals of the subject, determine a light control plan based on the physiological goals, the physiological data, environmental data, and time data. The system operates the light control valve to block or reduce blue light ambient radiation based on the light control plan, and generate, using the one or more radiation generators, therapeutic light radiation based on the light control plan.

Devices, systems, and methods can be used to deliver photobiomodulation therapy (PBMT) to the GI tract. For example, this document describes battery-enabled LED light source devices that can be deployed through or over an endoscope and anchored directly to the GI tract. Significant systemic effects can be produced by PBMT with application to one part of the body promoting beneficial anti-inflammatory and metabolic benefits in other remote sites promoted by enhanced mitochondrial function and mitokine signaling.

A system employing projected light upon objects or surfaces to determine a safe light wave length range of light to be emitted for treatment of the object or surface is provided. Light emitters are employed for projecting light waves upon the surfaces along with light reception components which are employed to receive reflected light wave ranges from such emitted light. Thereafter, a safe light wave range can be employed to treat or affect the object or surface.
