Certain examples involve controlling a circadian impact of a lighting system. For instance, a lighting system includes a first lighting fixture. The first lighting fixture includes at least one lighting element to illuminate a first space and a first controller to control a first light output of the at least one lighting element. Additionally, the lighting system includes a first background circadian system that provides a first modifying factor to the first controller of the first lighting fixture. The first modifying factor is associated with a first circadian impact profile that specifies a first circadian impact level in the first space. Further, the first controller of the first lighting fixture controls the first light output based on the first modifying factor.

The invention relates to an implantable illuminating device intended to be implanted in a living being with a view to locally illuminating a region of said living being, said device including a probe, said architecture being characterized in that it is produced from: an optical fiber that comprises a core, a cladding and a protective coating, a jacket, said architecture including: a plurality of successive segments along its longitudinal axis, each segment having a section containing a plurality of concentrically superposed layers, in which each segment includes a section containing a plurality of superposed layers that is different from the section of each adjacent segment.

A device includes an electromagnetic radiation delivery system such as a laser of light emitting diode infrared emitter configured for delivery of electromagnetic radiation within a sealed canal such as an ear canal, a fiber optic cable configured for delivering or capturing the electromagnetic radiation within the sealed canal, and a photo detector coupled to the fiber optic cable forming a portion of a voice communication system. Other embodiments are disclosed.

The present invention relates to a composition and a kit of parts for antimicrobial photodynamic therapy and uses of the same, the composition comprising (a) hydrogen peroxide, carbamide peroxide and/or sodium hypochlorite and (b) at least one photosensitizer capable of being activated by light emitted in the blue spectrum, in particular curcumin, riboflavin and erythrosine.

A laser irradiation device for performing treatment on human skin includes a casing that includes a grip part and a barrel part; a laser oscillator that is accommodated in the casing and configured to generate a laser beam to be irradiated through the barrel part; a contact sensor unit that includes electrodes exposed at the end of the barrel part and a contact sensing unit configured to sense an electric current flowing through the electrodes; and a skin treatment unit that is detachably connected to the barrel part and is operated based on electric signals transmitted through the electrodes of the contact sensor unit.

Systems are provided for compact implantable multi-site optical stimulation and/or combined electrical and optical stimulation of spinal cord, brain, dorsal root ganglion, peripheral nerve, or other tissue. High-power LEDs or other light-emitting elements are provided at the site of stimulation, avoiding complex fiber optics or other means for coupling light from a distant laser along a stimulator to target tissue. Colocation of electrical stimulation contacts and light emitters allows the same tissue to be stimulated electrically and optically, at the same time or according to an alternating or other pattern of combined electrical and optical stimulation. These stimulators can be used as part of permanently implanted systems and/or as part of temporary, percutaneous stimulator systems. Optical and/or combined electrical and optical stimulation can be provided for pain relief, to encourage wound healing in nervous or non-nervous tissue, or to provide other clinical benefits.

A method for treating or preventing nociceptive pain by administering an ethanol extract of Brazilian green propolis and compositions comprising this extract.

A system and method for identifying a post cecum position of an ingestible, phototherapeutic capsule traveling through a gastrointestinal (GI) tract to prevent intestinal blockage and facilitating deployment of additional phototherapeutic capsules in accordance with patient needs. The system employs an ex-vitro beacon in wireless communication with the capsule. The ex-vitro beacon is deployed in the vicinity of the McBurney's point to direct a beacon signal toward the cecum to identify capsule passage into the large intestine less prone to blockage.

A phototherapy system for treating a user can include an applicator, a controller, and a communication cable configured to couple the applicator and the controller. The applicator can include a light source, a thermal sensor, and a fan. The controller can be in communication with the applicator. The controller can be configured to receive a predetermined treatment regimen to be applied to the user via the applicator. A method for treating skin presenting psoriasis includes providing a phototherapy system. The user can select a skin type on the controller. The use can place the applicator adjacent to the skin presenting psoriasis, eczema, or vitiligo. The user can receive a light therapy treatment from the applicator, whereby the psoriasis, eczema, or vitiligo has been treated.

A transcranial stimulator includes a main body formed in a shape that covers part or all of a head surrounding a skull, a light emission module configured in the main body to transmit light energy to a brain, and a controller configured to control an operation of the light emission module, wherein the light emission module includes a first optical device emitting light in a wavelength band of 630 nm to 680 nm toward the skull and a second optical device emitting light in a wavelength band of 780 nm to 990 nm toward the skull.
