Mammalian skin is treated and advantageously smoothed, for example to remove wrinkles, lines, warts and scars therefrom, by topically applying thereto a composition which comprises at least one laser-absorbing chromophore formulated into a physiologically acceptable carrier, diluent or vehicle therefor, and laser-irradiating the skin thus treated with an intensity sufficient to locally convert the light energy into heat energy in the applied composition and advantageously effecting tissue ablation of the surface of the treated skin, said applied composition and the thickness thereof having an absorbance at the emission wavelength of the laser such that the light energy transmitted into the skin generates no undesired irreversible tissue or cell damage.
A method for the reduction in healing time for a wound on the skin of a mammalian patient. The method comprises the steps of providing an optical radiation apparatus with a handpiece communicating therewith, energyzing the optical radiation apparatus to provide a beam of light, and directing the light beam onto a wound or surgical site of a patient. The beam has a wavelength range of about 530 nm to 1000 nm and the beam has a fluence range of from 2 J/cm.sup.2 to 5 J/cm.sup.2. The beam is preferrably generated by a pulse dye laser apparatus.
The present invention provides for a device, a method, and a treatment system for chronic disease conditions. The present invention was designed using the theoretical concepts of Quantum Biology. The principles of operation are based on the device's ability to stimulate a Bose-Einstein condensate and excitation of Frolich resonance in living tissue The wavenumbers necessary for this excitation are derived from the solution to the equations for optical phonon scattering in living tissue generated by optical photon excitation. The establishment of this degeneracy condition induces a super conducting state in the tissue. This super conducting state facilitates DNA replication, transcription and translation, thereby allowing the proper formation or regeneration of healthy tissue. This superconducting state provides the conditions necessary for establishing the violation of time reversal invariance in living tissue.
The invention relates to a device (1) for shortening hairs (3), in particular growing from human skin (5). The device (1) has a laser source (7) for generating a laser beam (9) during a predetermined pulse time, an optical system (15) for focusing the laser beam into a focal spot (25), and a laser beam manipulator (17) for positioning the focal spot in a target position. According to the invention, a dimension of the focal spot (25) and a power of the generated laser beam (9) are such that, in the focal spot (25), the laser beam has a power density which is above a characteristic threshold value for hair tissue above which, for the predetermined pulse time, a laser induced optical breakdown (LIOB) phenomenon occurs in the hair tissue. The LIOB phenomenon results in a number of mechanical effects in the hair tissue, such as cavitation and the generation of shock waves, which damage the hair (3) in positions surrounding the position in which the LIOB phenomenon occurs. From experiments it appeared that, with a sufficient amount of total energy of the laser source (7), the LIOB phenomenon can be used to completely break and thus to shorten a hair. An advantage of the device (1) according to the invention is that the amount of total energy, which is necessary to completely break a hair (3), is at such a level that irritation and damage of the skin tissue surrounding the hair are limited to an acceptable level or even completely prevented.
A method for photoselective vaporization of uterine tissue includes delivering laser radiation to the treatment area on the tissue, via an optical fiber for example, wherein the laser radiation has a wavelength and irradiance in the treatment area on the surface of the tissue sufficient because vaporization of a substantially greater volume of tissue than a volume of residual coagulated tissue caused by the laser radiation. The laser radiation is generated using a neodymium doped solid-state laser, including optics producing a second or higher harmonic output with greater than 60 watts average output power. The delivered laser radiation has a wavelength for example in a range of about 200 nm to about 650 nm, and has an average irradiance in the treatment area greater than about 10 kilowatts/cm.sup.2, in a spot size of at least 0.05 mm.sup.2.
Methods and systems are disclosed for phototreatment in which replaceable containers comprising one or more adjuvant (consumable or re-useable) substances are employed. The adjuvant substance can be, for example, a topical substance or a coolant. Systems are disclosed for using a topical substance to detect contact of a phototreatment device with a tissue, detect speed of a phototreatment device over the tissue, detect regions of tissue that have been treated by a phototreatment device and/or to provide other benefits to the tissue such as improved skin tone and texture, tanning, etc. Safety systems are also disclosed that ensure that a proper consumable substance and/or container is connected to a phototreatment device and/or directed to a proper target. Additionally, cooling systems and methods that utilize phase change materials for extracting heat from a light generating device are disclosed.
