Abstract: An apparatus for intraluminal energy treatment and method thereof includes an energy source for insertion into a lumen of a body and having an output end for energy-emission within the lumen and a cooling device with a cooling member adapted to be positioned on the skin surface proximate the lumen along a part of the lumen to be treated for cooling tissue proximate that part of the lumen.

Abstract: An optical fiber delivery system comprising a number of first optical fibers, preferably in a bundle, and a second optical fiber light from a number of light sources are coupled into the second fiber via the first fibers. The emitting diameter of the first fibers is adjusted to match the core diameter and acceptance angle of the second fiber by reducing/increasing the number of emitting light sources being coupled to the first fibers. Thereby the brightness and efficiency of the light beam is preserved throughout the entire system in particular when the beam is passed from the first fibers to the second fiber, even if the power is reduced or the diameter of the second fiber is very small. Accurate knowledge of the optical beam which is eventually emitted by the second fiber is obtainable. Further, a method for delivering optical power from a number of light sources using the fiber delivery system.

Abstract: A method and apparatus for tissue treatment. A handpiece contains a light source for emitting a light beam toward the tissue. A detector detects at least one tissue parameter along a path during an initial scan. This information is stored and a map of the parameter produced. A light beam controller controls a light beam parameter and controls a deflector in order to apply the light beam to the tissue in a predetermined path.

Abstract: An apparatus for tisue treatment is provided, comprising a light source for emission of a treating light beam towards a target surface and illuminating a spot on the target surface, movable deflecting means for deflection of the treating light beam, moving means for moving the deflection means, and deflecting control means being adapted to control the moving means so that the treating light beam traverses a target surface area stepwise with steps that are greater than half the diameter of the spot. Furthermore, a controlled overlap between illuminated spots may be provided, for example by user selection. The apparatus may be provided in a hand piece. The apparatus may preferably be used for removal of hairs, but also photocoagulation of veins may be obtained.

Abstract: A handpiece for cosmetic tissue treatment includes an input connector for connection of a first beam-outlet end of a first optical fiber to the handpiece and for alignment of the first optical fiber with an axis of the handpiece so that a first light beam emitted from the first beam-outlet end is transmitted substantially along the axis, a movable first deflecting device for deflection of the first light beam into a second light beam, and an output for emission of the second light beam towards a target surface. The handpiece may be used for ablating a thin epidermal layer of the derma of a patient and also marks on the tissue such as marks from chloasma, liver spots, red spots, tattoos, blood vessels just below the surface, etc. In addition, warts, wounds, hair follicles, etc., may be ablated or treated.

Abstract: An optical system comprising a light source and a beamsplitter for splitting the beam of the light source into a primary output beam and a secondary output beam. The power of the secondary output beam is a substantially fixed small percentage (preferably less than 0.5%, such as less than 0.1%) of the power of the primary output beam, at least within a certain wavelength range. Thus, measuring the power of the secondary output beam provides a precise measure for the power of the primary output beam. May be used for controlling/adjusting the output power of the primary output beam, e.g. for keeping the power substantially constant. The fixed percentage is preferably invariant to wavelength variations, at least within a certain wavelength range. Preferably, a low variation in power (ripple) is induced.

Abstract: A connector assembly for releasable connecting an optical fiber to a laser apparatus to allow a laser beam to be coupled into the fiber. Comprises a first connector part being positioned at the fiber and a second connector part being positioned at the laser apparatus. When the first and second connector parts are not connected, the first connector part protects the tip of the fiber. The first connector part further comprises a window positioned in the beam path of the laser beam emitted from the laser apparatus for further protection of the fiber tip. Dust and dirt is prevented from access to the fiber. The connector assembly may comprise information means for containing information about the fiber and/or a light emitting device, and information may be transferred from a handpiece to the information means via electrical, optical, mechanical and/or magnetical means.

Abstract: An apparatus for cosmetic tissue treatment having a light emitter for emission of a light beam. The light beam is directed towards a target area to be treated, and a detector detects tissue parameters in the target area. A light beam control controls at least one parameter of the first light beam in response to the detected at least one tissue parameters. The tissue parameters can include texture, elasticity, size, and shape. The apparatus may be used for ablating a thin epidermal layer of the derma of a patient and also marks on the tissue such as marks from chloasma, liver spots, red spots, tattoos, blood vessels just below the surface, etc., as well as warts, wounds, hair follicles, etc., may be ablated or treated.
