A stimulus is configured to treat astigmatism with changes in retinal thickness, independently of, or in combination with, treatment for myopia. In some embodiments, a stimulus pattern is arranged with respect to an astigmatic axis of the eye to decrease ocular growth in relation to the astigmatic axis. In some embodiments, the apparatus is configured to direct light to regions of retina outside the macula in relation to the astigmatic axis of the eye. In some embodiments, the intensity is modulated to provide the effect. A lens, such as a contact lens or spectacle lens may be configured with a plurality of light sources, such as projection units having a light source and focusing optics that work together to project anteriorly or posteriorly defocused images onto the retina at locations eccentric to the fovea.

A sterilizing mouthpiece assembly for reducing the airborne transmission of infectious diseases includes a mouthpiece for positioning in a user's mouth. A shelf is integrated into the mouthpiece and a wedge extends upwardly from the shelf. A plurality of first light emitters is each of the first light emitters is integrated into the mouthpiece and each of the first light emitters emitting light in the ultraviolet spectrum to sterilize the inside of the user's mouth. A plurality of second light emitters is each positioned on the wedge and each of the second light emitters emits light in the ultraviolet spectrum to sterilize the inside of the user's mouth.

A hand-held light treatment device configured with interchangeable emitter heads that are pre-programmed with desired treatment protocols and updated from a remote store of treatment protocols. The removable emitter heads each contain one or more treatment LEDs, a tracking light, a task light, a proximity sensor, and a control module. A tip is attached to the emitter head, either removably or integral therewith. In in one embodiment, the tip is integral with the emitter head and emits light perpendicular to the handle. Some embodiments have tips of various shapes that attach to the emitter heads, which permits a single device to direct the emitted energy at nearly any direction. The tips can be disposable or reusable. The light-emitting device may be used in conjunction with distilled water to treat infections, sterilize wounds or to minimize infection prior to surgical closure.

A method for re-configuring a biomedical laser device. The biomedical laser device is pre-configured to be operable in one or more operational modes, and is provided with set of operational parameters that are employed for at least one of: given medical procedure, given medical treatment, activation of given drug, illumination of given dye. The method includes collecting information indicative of light output properties of biomedical laser device measured during given operational mode; detecting deviation in measured light output properties with respect to predefined light output properties for given operational mode; determining new set of operational parameters that are to be employed for at least one of: new medical procedure, new medical treatment, activation of new drug, illumination of new dye; and sending new set of operational parameters to biomedical laser device for re-configuring biomedical laser device to be operable in a new operational mode.

Described herein are methods, devices and systems for stimulating neural oscillations in the high gamma wave frequency, in particular to promote neuronal plasticity and removal of the perineuronal net. Such methods, devices and systems are useful for treating neuropsychiatric disorders such as schizophrenia and depression in a subject in need thereof.

An object of the present invention is to provide a chair-type phototherapy device that enables a patient to perform light irradiation accurately targeted at a treatment site in a seated position on a chair and consequently achieves effective phototherapy even when the treatment site is in the back region that the patient is unable to see, for example, as in light irradiation for dysuria patients and patients with pain, and the patient performs light irradiation by himself/herself at home. The present invention provides a chair-type phototherapy device having a seat on which a patient is seated. The chair-type phototherapy device includes a radiation module configured to emit radiation light toward a living body, a drive module positioned behind the patient for moving the radiation module, and a fixing module fixing the drive module to the seat.

A device including a semi-rigid shell forming an external surface with at least part of the shell adapted to contact tissue of a body cavity. The shell includes a treatment band formed around the shell, a first portion forming a rounded end of the device that is distal to the treatment band, and a second portion formed around the circumference of the shell and located proximal to the treatment band. The device further includes a vibration mechanism configured to case the shell to vibrate, a sensor configured to provide sensor data upon contact with the tissue, and a processor configured to receive the sensor data and to use the sensor data to produce parameters of the tissue.

The device includes a laser source (7) adapted to emit a laser radiation at a wavelength between around 620 nm and around 750 nm, and a handpiece (5). The handpiece in turn includes an applicator (11) with a contact surface with the epidermis defining a window (11.1) for the passage of a laser beam (F) toward the epidermis (E) of a subject to be treated. A waveguide (10) conveys the laser radiation from the laser source (7) to a scanning system (17) of the handpiece.

A method and system for of treating type 1 includes implanting genetically modified islet cells under a capsule of or within an organ, implanting a microsystem adjacent the islet cells, said microsystem, comprising a light emitting diode stimulator comprising a plurality of light emitting diodes, determining a glucose level in a body and controlling the microsystem to selectively illuminate the islet cells to secrete insulin or glucagon or both based on the glucose level.

The present invention is comprised of a novel solar radiation simulation device that simulates the sun by radiating the same spectrum of wavelengths, with the accompanying power levels, as the sun when the sun projects energy upon the Earth in accordance with the time of the day, year, and location. It will bring “the sun inside.” The device can be controlled manually by an end-user or can include pre-programmed modes that control settings of the device or can be dynamically controlled through the input from solar light meters located around the world. This device improves human health but can also be used as a typical light source and can even function as an entertainment device.
