A phototherapy apparatus includes: a light irradiation module that radiates light for treatment; and a spacer that is disposed on a light output side of the light irradiation module and contacts a surface of a body to keep a distance between the light irradiation module and a part to be treated on the surface of the body constant, in which a spacer opening that avoids contact of the part to be treated and the spacer is formed on a surface of the spacer, which contacts the surface of the body.

The invention provides a laser system and method for administering multiple beams of laser energy in tissue treatment applications. The system administers the beams simultaneously in a distribution pattern of spatially separated overlapping and non-overlapping regions on a tissue. The simultaneous administration and distribution pattern permit the beams to propagate within a tissue without producing the light scattering effects that characterize the sequential application of multiple laser beams to a tissue. The laser system can comprise tissue cooling and laser cooling components.

Provided is a simple light irradiation apparatus capable of performing uniform irradiation even on to a treatment area having a curved surface and capable of suppressing excessive heating caused by light irradiation. The light irradiation apparatus (10) includes a polymer gel layer (3) that covers the treatment area (2) on skin (1), an LED protective layer (6) that closely adheres to the polymer gel layer (3), and a substrate (5) on which LEDs (4) closely adhered to the LED protective layer (6) are arranged thereon. A current control apparatus (8) which lights the LEDs (4) controls irradiation intensity and stops irradiation when. reaching a demanded dose amount.

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.

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 cooling device for cooling an object contained in a vacuum chamber. The cooling device is insertable into and removable out of a boot housed by the vacuum chamber. The boot is in thermal contact with the object. A distal portion of the cooling device comprises a cold station and a coupler thermally connected to the cold station. The coupler comprises at least two mobile contacts thermally connected to the first cold station. The cooling device also comprises a driving means and a mechanical transmission connecting the driving means to the at least two mobile contacts. The driving means and the mechanical transmission are configured to move the at least two mobile contacts radially inwardly and outwardly to respectively loosen or make a conductive thermal contact between the cold station and the boot.

Methods and systems one or more for performing intra-luminal ultraviolet therapy for treating and/or ameliorating a gastrointestinal tract inflammation and/or infection are provided. In one example, a light delivery catheter may include a light emitting portion and non-illuminating portion, wherein the light emitting portion may include one or more UV transparent balloons. In some examples, the UV light source is configured to emit narrow-band light having wavelengths in a range between 335 nm and 349 nm.
