  • Patent number: 8870856
    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 higher 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.

  • Patent number: 8656931
    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. In 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: 7998181
    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.

  • Patent number: 7878206
    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.

  • Patent number: 7465307
    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: 20070282318
    Abstract: Disclosed herein are systems and methods that reduce, remove, shape, and/or sculpt sub-dermal fat layers by selectively heating fat tissue, or that reduce the appearance of cellulite, using low frequency RF energy applied through one or more skin contacting electrode carried on a handpiece. The handpiece is manipulated manually or automatically to continuously move the electrode(s) across the skin surface during RF delivery. A motion detector may be employed to determine the speed and/or direction of movement of the electrode, and operating parameters such as the amount of applied RF power may be modulated in response to feedback from the motion detector. One or more cooling modalities including thermoelectric cooling, and/or forced air cooling may be used to cool or minimize heating of the skin.
