Abstract: A method and system for skin tightening comprises a hollow cannula that contains an optical fiber connected to a laser source. The cannula is inserted subcutaneously into a patient so that the end of the fiber is located within the tissue underlying the dermis. The source emits an output pulse that is conveyed by the fiber to the dermis, where the pulse causes collagen destruction and shrinkage within the treatment area. Radiation from the skin surface is detected to prevent non-reversible damage to the dermis, such as skin necrosis and excessive collagen melting. This method of sub-cutaneous laser treatment can also be used to treat striae, or stretch marks.

Abstract: A phototherapy apparatus for the treatment of psoriasis which includes a dielectric-discharge excimer lamp 32, which is equipped with a reflector 34 and optical system 36 for ensuring a substantially uniform density of energy, is mounted on a maneuverable arm 40. The arm 40 is mounted to a stand 24. An electronic control unit 20 and a radiofrequency power supply unit 22 are connected to the lamp 32. A pipe of a cooling circuit 9 is connected to the lamp 32 via the arm 40. The pipe 9 connects to an air-liquid exchanger 3 with a de-ionizer having a temperature sensor 5 and a sensor 7. The sensors 5, 7 and 10 are connected to a microcontroller 12, which is connected to an operating panel 14 and to a display 16 and a printer 18. A hardware container 26 is provided on the stand to hold the radiofrequency power supply unit 22, the printer 28, the microcontroller 12, the control panel 30, and the air-liquid exchanger 3.

Abstract: An essentially u-shaped discharge lamp (13) comprises a gaz fill and a pair of electrodes (15) at its ends. The lamp (13) way be comprised in a handpiece (1) for treating a surface by means of electromagnetic radiation.

Abstract: A device for laser treatment of painful symptomatologies with a first laser source 1, a conveying device for conveying the laser energy to a hand unit 5, and optical structure 11, 13 for defocusing the laser beam.

Abstract: A method for laser anti-inflammatory treatment of painful symptomatologies and for tissue regeneration is described.

Abstract: A device and method for the removal of subcutaneous adipose layers with a laser source, optical fiber for conveying the laser ben emitted by the first source and a hollow needle f or guiding the fiber. The fiber ends in the vicinity of the end of the needle. The laser beam is generated with an intensity and a wavelength for liquefying, and maintaining liquid, the adipose cells. The laser beam from the optical fiber irradiates adipose cells in the adipose layer to transform the adipose cells into, and maintain the adipose cells as, a liquid substance.

Abstract: The device for the removal of subcutaneous adipose layers comprises a first laser source (1), optical fiber conveying means (3) for conveying the laser beam emitted by said first source (1) and a hollow needle (7) for guiding the fiber, said fiber ending in the vicinity of the end of the needle.

Abstract: The device for deflecting a laser beam comprises a mirror (1) and means for orientating the mirror according to a predetermined equation for the controlled deflection of the laser beam (F). The mirror (1) is supported so that it can oscillate about two axes and the means for orientating the mirror comprise a plurality of electromagnets (11A, 11B, 15; 13A, 13B, 17) supplied with currents which are controlled and variable in time (I.sub.15, I.sub.17) to exert magnetic forces on said mirror (3).

Abstract: The present invention relates to an electronically-controlled plasma ignition device for internal combustion engines.
