  • Publication number: 20070265604
    Abstract: A dermatological treatment method includes directing laser energy having a wavelength of 2.79 ?m onto skin. According to disclosed methods, the energy can function to ablate a first portion of epidermal tissue, coagulate an underlying second portion of epidermal tissue, and promote collagen formation in tissue of the underlying dermis. Tn an exemplary treatment apparatus, a laser using a YSGG gain medium is mounted in a handpiece. The handpiece may include a two-axis scanner to allow for uniform scanning of the energy over the tissue surface.

  • Patent number: 7291140
    Abstract: The invention comprises a system and method for providing for pulses or relatively low energy light to an area of skin being treated. Typically, these low energy pulses will include shorter wavelength light, and will provided for multiple pulses of light for the area being treated. The pulse width is determined by the characteristics of a storage capacitor and the flashlamp. The overall system design can be relatively simple, and the operation of such a system can allow for operation by relatively inexperienced users. Due to the low energy pulse, it can be necessary to apply a greater overall amount of energy per treatment area relative to other previous systems, but due to the relatively long period of time between pulses the operation is such that risk of injury is significantly reduced relative to prior systems.

  • Patent number: 7208007
    Abstract: A fluorescence concentrator system that provides for high brightness light source. The system can include a host doped with fluorescent material, which is optically pumped by an adjacent illumination source. The fluorescence concentrator captures a portion of the isotropically emitted fluorescent light and guides it to an output surface. The fluorescent energy emerging the output surface provides a high brightness light source suitable for a number of applications. For example, the fluorescence concentrator system can be used as the light source in a medical apparatus suitable for various aesthetic procedures. Further aspects of the fluorescent concentrator system can include providing for controlling the illumination source to output pumping energy suitable for high energy applications.

  • Publication number: 20060293727
    Abstract: The invention comprises a system and method for treating an exposed tissue of a patient with a light energy. A plurality of light emitting diodes are disposed over an area of a supporting structure. The light emitting diodes emit light energy. The light energy comprises a substantial band of wavelengths between about 380 and 800 nm. The light emitting diodes are optically coupled to the exposed tissue of the patient. A driver circuit is electrically coupled to the light emitting diodes for driving a current through the plurality of light emitting diodes. An average irradiance of the light energy emitted from the area by the light emitting diodes is at least about 30 mW per square centimeter during a treatment. In some embodiments, the light energy emitted from a first light emitting diode substantially overlaps with light energy emitted from several adjacent light emitting diodes as the light energy propagates toward the tissue.

  • Publication number: 20060195073
    Abstract: System and methods for minimally invasive treatment of snoring are described. According to one system and method, laser energy is applied to tissue of a soft palate and/or uvula to create a pattern of multiple treatment spots in the tissue. According to another system and method, electromagnetic energy from a filament light source is impinged of soft palate and/or uvula tissue to achieve volumetric heating of the tissue. The systems and methods increase rigidity and/or reduce laxity of the tissue, and/or volumetrically reduce the tissue, thereby diminishing snoring.

  • Publication number: 20060122585
    Abstract: A hair removal device (22) includes a cooling surface (34) which is used to contact the skin (6) prior to exposure to hair tissue-damaging laser light (74) passing from a radiation source (36) through a recessed window (46). The window is laterally offset from the cooling surface and is spaced apart from the cooling surface in a direction away from the patient's skin to create a gap between the window and the skin. The window preferably includes both an inner window (46) and an outer, user-replaceable window (48). The laser-pulse duration is preferably selected according to the general diameter of the hair.

  • Publication number: 20050177141
    Abstract: A system and method using a gas discharge to provide for dermatological treatments, such as hair removal. The system provides for varying the spectral output of the gas discharge lamp by varying the current density through the lamp. This ability to control the spectral output is particularly beneficial where the a variety of different skin types and hair types are being treated for hair removal. By changing the current density through the lamp, the spectral output from the lamp can be changed. Thus, where a power supply provides the ability to control the amount of current density through the lamp, the spectral output from the lamp is controlled and selected for a particular skin type being treated.

  • Publication number: 20050171581
    Abstract: A system and method for using a light source to treat tissue with NIR light. The operation provides for generating higher temperatures in deeper layers of tissue relative to shallower layers of tissue. The increased temperature in dermal layers can operate to induce collagen shrinkage, or remodeling. One of the light sources for providing a broad spectrum of NIR light is a filament light. The light from the filament lamp can be selectively filtered, and after filtering this light is applied to the skin, where the selective filtering can enhance the ability to elevate the temperature of deeper layers of tissue, relative to layers of tissue which are closer to the surface of the skin.

  • Publication number: 20050137655
    Abstract: A system and method for providing light treatments to a patients skin, which could include both dermal and epidermal regions. The system and method utilize multiple hand pieces where each hand piece can deliver light from a different light source. The system and method provide for control over the different light source corresponding to the different hand pieces based on whether the hand pieces are held in storage positions in a hand piece management unit. A control unit of the system provides operates to cause a user interface display to communicate information to a user based on the positions of the different hand pieces. Further, the system and method can provide a user with access to different aspects of the systems operation based on the positions of the hand pieces.

  • Publication number: 20040147985
    Abstract: A power supply comprising a chopper circuit with an inductive filter element may drive a flashlamp to direct flashlamp radiation to a patient's skin. The waveform may have a generally constant current value and may be substantially independent of pulse width repetition rate and of pulse repetition rate. The flashlamp may be selected according to the type of treatment and the expected width of the treatment area. The wavelength of the radiation to be directed to a patient may be limited to a shallow tissue-penetrating, strongly melanin-absorbing wavelength spectrum, such as at most about 590 to 850 nm or at most about 590 to 700 nm. The chosen wavelength spectrum may be-within the UVA through UVB wavelength spectrum so to cause localized pigmentation in a patient's skin. The chosen wavelength spectrum may be a continuous wavelength spectrum.
