A method for treating a medical condition in a patient in need thereof is provided. The method includes applying light to the patient thereby stimulating the immune system of the patient, wherein the applying includes irradiating substantially the entire body of the patient with high intensity blue light having a wavelength, intensity, and duration configured to provide immune system stimulation sufficient to treat the medical condition, the stimulation including increasing the population of T-cells in the patient's bloodstream to treat the medical condition. Also included is a method for activating T cells in a subject in need thereof.

A whitening light includes a mouthpiece having a light array arranged along the mouthpiece for directing light onto an exposed portion of teeth of a user. The whitening light includes a rear portion comprising a first power source communicably coupled to the light array and a first charging mechanism configured to receive power transferred from a second charging mechanism located on a case for the whitening light. The first power source includes a rechargeable battery charged by the second charging mechanism to a power output sufficient to power the whitening light to emit light configured to whiten teeth upon selection of a button on the rear portion of the whitening light to commence a treatment session, to emit the light for a predetermined duration corresponding to a duration of the treatment session, and to automatically switch the light array to an off-setting following expiration of the predetermined duration.

A method of administering 5-aminolevulinic acid (ALA) to a patient uses an adjustable illuminator for photodynamically diagnosing or treating a surface and which includes a plurality of first panels and at least one second panel. The plurality of first panels have wider widths and the at least one second panel has a narrower width. The narrower width is less than the wider widths. The illuminator further includes a plurality of light sources, each mounted to one of the plurality of first panels or the at least one second panel and configured to irradiate the surface with substantially uniform intensity visible light. The plurality of first panels and the at least one second panel are rotatably connected. The at least one second panel is connected on each side to one of the plurality of first panels. The second panel acts as a “lighted hinge” to reduce or eliminate optical dead spaces between adjacent panels when the illuminator is bent into a certain configuration.

A light therapy system may comprise a first light therapy device including a first control panel and a second light therapy device including a second control panel. In some embodiments, each of the first light therapy device and the second light therapy device is configured to operate in an independent mode, a follow mode, and a lead mode. When the first light therapy device operates in the independent mode, the first light therapy device performs operations as instructed by the first control panel. Similarly, when the second light therapy device operates in the independent mode, the second light therapy device performs operations as instructed by the second control panel. In some embodiments, the light therapy device operating in the follow mode performs operations as instructed by the light therapy device operating in the lead mode.

A method of enhancing penetration of a topical composition of 5-aminolevulinic acid (ALA) into tissue for photodynamic therapy includes topically applying ALA to a treatment area to be treated with photodynamic therapy. The method further includes, after the ALA is applied to the treatment area, covering the treatment area with a low density polyethylene barrier. The treatment area is covered with the low density polyethylene barrier prior to light treatment to minimize transepidermal water loss from the treatment area.

A phototherapy apparatus present disclosure includes a treatment site detection unit, a treatment unit, and a control unit. The treatment site detection unit detects a treatment site of a body. The treatment unit includes a first moving unit moving in a vertical direction, a body unit, and a light source unit including a plurality of light sources emitting therapeutic light. The control unit controls the operation of the first moving unit and the light source unit. Here, when the treatment site detection unit detects the treatment site, the control unit controls the first moving portion to bring the light source unit into close contact with the treatment site. In addition, when the light source unit comes into close contact with the treatment site, the control unit causes the light sources located at the treatment site to emit therapeutic light.

A stimulation device includes an energy source; an electronics unit; an actuator that is coupled with the electronics unit and/or the energy source. The electronics unit includes a controller. The energy source, the electronics unit and the actuator are arranged in a housing. A fixing unit which is coupled with the housing and affixes the stimulation device on a heart or in a heart. The actuator emits electromagnetic waves for the stimulation of genetically manipulated tissue, and the controller controls the stimulation of the tissue by way of the electromagnetic waves of the actuator.

In one aspect, a method is provided for performing light therapy on a subject. The method comprises providing a device which emits electromagnetic radiation that oscillates between at least first and second distinct polarization states; and illuminating the subject with the emitted electromagnetic radiation. In another aspect, a fixture is provided which comprises a first source of electromagnetic radiation which emits electromagnetic radiation in a first polarization state; a second source of electromagnetic radiation which emits electromagnetic radiation in a second polarization state which is distinct from said first polarization state; and an oscillator which oscillates electromagnetic radiation output by the fixture between at least said first and second polarization states.

Modulated light therapy devices for treatment of dermatological disorders of the scalp are provided. An exemplary device includes a flexible printed circuit board (FPCB) supporting at least one light emitting device having an emitter height. The FPCB includes multiple interconnected panels and bending regions defined in and between at least some of the interconnected panels as to allow the FPCB to be configured in a concave shape to cover at least a portion of a cranial vertex of the patient. At least one light-transmissive layer proximate to the FPCB is configured to transmit (e.g., incoherent) light emissions generated by at least one light emitting device. At least one standoff is configured to be arranged between the FPCB and the scalp of the patient, wherein the at least one standoff includes a standoff height that exceeds the emitter height.
