  • Patent number: 7331983
    Abstract: The present invention provides a system and method for improved biostimulative effect through the use of low mode/oligomode fibers to transport coherent light to a treatment site. Oligomode fibers or groups/bundles of oligomode waveguides for the relevant irradiation wavelength are used for radiation transport. Selective leakage of the radiation from this delivery system is achieved at the desired application sites of the biostimulation by suitable means, one being evanescent wave decouplers. The result is a low intensity exposure of coherent light to tissue or organic material that is more effective than conventional biostimulative procedures. Delivery systems based on such waveguides can cover large areas due to the low transmission losses of the waveguide. The waveguide can be inserted into hydrocultures or earth to provide radiation and thus biostimulation of seeds and cuttings in situ. Coherent radiation can also improve the health, healing and fertility of animals.

  • Patent number: 7160287
    Abstract: An apparatus and method to apply photo-stimulation, photo-dynamic therapy and/or ablation laser treatment to biological tissue. The apparatus includes a plurality of radiation energy sources, preferably laser beams. Additionally, the apparatus allows either a single wavelength or a combination of various wavelengths, either coincidentally or adjacently, to be utilized to achieve a desired treatment effect. Laser beams are transmitted to the treatment area by one or more fiber optic cables which terminate at an assembly structured to collimate the emitted radiation prior to application to the tissue. In addition, the apparatus includes a focal length setting mechanism which assures that a constant, fixed distance exists between the point of discharge of the laser beam and the biological tissue, thus assuring a constant energy density at the point of application. A method is presented for applying photo-stimulation, photocollagen stimulation and/or ablation laser treatment utilizing the above apparatus.

  • Patent number: 7101364
    Abstract: A method and apparatus for intrastromal refractive surgery is disclosed wherein tissue at selected locations within the stroma of the cornea is photoablated using a pulsed laser beam. The apparatus includes an optical system for forming a shaped laser beam having a waist at a predetermined distance from the optical system. The pulse duration and pulse energy of the laser beam are selected to cause ablation to occur in front of the waist (i.e. between the waist and the optical system). To achieve this, a pulse energy is used that exceeds the minimum pulse energy required for ablation at the waist. By ablating in front of the waist, a relatively large ablation zone (per pulse) is created (compared to ablation at the waist). Furthermore, while the laser is scanned through the cornea to effectuate a refractive change, the optical system maintains a uniform waist for the laser beam.

  • Patent number: RE40316
    Abstract: The concentration of glucose in the anterior chamber of an eye is non-invasively measured by guiding a beam through a polarizer (4), a quarter wave plate (6), a polarization modulator (20), and an analyzer (7). After initializing the polarizer and the analyzer to extinguish the beam, it is guided parallel to the iris (56) of the eye (50) and introduced into the anterior chamber (57), wherein it is refracted, impinges on and is reflected from the iris, and exits the anterior chamber approximately collinear with the portion (55A) of the beam incident on the anterior chamber. The beam then is guided onto a detector (10), and a sufficient signal is applied to the polarization modulator to extinguish the beam. The signal represents the glucose concentration in the patient's blood.
