The present invention provides method and apparatus for treating tissue in a region at depth while protecting non-targeted tissue by cyclically applying cooling to the patients skin, and preferably to the region, and by applying radiation to the patient's skin above the region to selectively heat tissue during and/or after cooling is applied. At least one of cooling and radiation may be applied by successively passing a continuous output applicator over the patient's skin. Treatment may also be enhanced by applying mechanical, acoustic or electrical stimulation to the region.

Method and apparatus for treatment of cutaneous and subcutaneous conditions

A laser induced thermo-acoustical system has a waveguide for propagating laser radiation to an absorbing layer of a tip. The tip has an absorbing layer serving to absorb the laser radiation propagating through the waveguide. The absorbing layer has such an absorption coefficient that upon absorbing the laser radiation the absorbing layer heats up to boil a quantity of a liquid when the tip is surrounded by the liquid. A laser induced thermo-acoustical method calls for providing a waveguide for propagating laser radiation to the absorbing layer of the tip to be at least partially absorbed by the absorbing layer and to boil a quantity of the liquid surrounding the tip and generating the stream of liquid. The laser induced thermo-acoustical streaming of the liquid is used, in particular, for the treatment of a root canal and periodontal pockets.

Method and apparatus for laser induced thermo-acoustical streaming of liquid

A surgical device based on the concept of controlling the laser power during laser surgery based on optical and other signals from the tip and the tissue is described. A laser surgical system generally comprises several basic components, such as a laser, a delivery system, a tip and a control system. A tip may be considered as a particular case of a thermo-optical tip (TOT). TOT is an optical and mechanical element which could be used to modify or treat soft and hard tissues, including cutting, coagulation, vaporization, carbonization, and ablation of tissues.

Dental surgical laser with feedback mechanisms

A method and apparatus are provided for processing a hard material, for example a hard biological material such as dental enamel or bone, with optical radiation. A treatment zone of the material is selectively cleaned of ablation products and other dirt to enhance processing efficiency, and a tip through which the optical radiation is applied to the treatment zone of the hard material is spaced slightly from the treatment zone during at least a portion of the time that hydrating fluid is being applied to the zone and/or while air or another gas is applied to the zone to clean the surface thereof.

Method and apparatus for processing hard material

The present invention is a number of methods and devices for tooth rejuvenation and hard tissue modification comprising applying a layer of a peroxide-free composition to a tooth surface. The applied composition comprises an aqueous solution of one or more edible acids. The composition has a pH selected from the range of about 0.5 to 5. After the treatment the composition is removed from the tooth surface. In various embodiments of the invention the pH of the composition can range between about 0.5 and 3, a narrower range being between 1 and 1.75. Hard tissue rejuvenation comprises forming a post-treatment layer having a composition which is different from that of the hard tissue by selectively heating a porous layer on the hard tissue.

Method and apparatus for tooth rejuvenation and hard tissue modification

The present invention relates to a method and an apparatus for permanently or temporarily removing human hair, for miniaturizing the same or for changing the color thereof. This apparatus can also be used for coagulating blood vessels, veins or a selective injury of the derma collagen in order to regenerate the same. This apparatus uses one or more incandescent lamps () in which the radiation spectrum () can be modulated in order to heat slowly and efficiently the derma () and in order to heat locally the hair follicles (). This apparatus also includes an optical system that converts the blue-green portion of the spectrum of the incandescent lamps () into a red region of the spectrum, that provides a highly efficient concentration of converted radiation from the incandescent filament () of the lamps () on the area of biological tissues to be treated, and that ensures a repeated recirculation towards the skin () of the radiation scattered by the same.
