    Abstract: Apparatuses and methods are disclosed for applying laser energy having desired pulse characteristics, including a sufficiently short duration and/or a sufficiently high energy for the photomechanical treatment of skin pigmentations and pigmented lesions, both naturally-occurring (e.g., birthmarks), as well as artificial (e.g., tattoos). The laser energy may be generated with an apparatus having a resonator with the capability of switching between a modelocked pulse operating mode and an amplification operating mode. The operating modes are carried out through the application of a time-dependent bias voltage, having waveforms as described herein, to an electro-optical device (e.g., a Pockels cell) positioned along the optical axis of the resonator.

    Abstract: A method for cosmetically treating skin tissue is disclosed in which a combination of laser energy and RF energy is applied to the skin tissue. In the method, a microchannel is first formed in the skin tissue having a length, a depth and a width by ablating the skin tissue. After that, RF electrodes are placed on the skin tissue on either side of the width dimension of the microchannel, followed by activation of RF energy to drive RF energy below the depth of the microchannel formed, and this the RF energy is driven deeper into the skin tissue than would have occurred in the absence of the microchannel.

  • Patent number: 10548772
    Abstract: A change in the response of the cornea to ultrasonic energy directed into the cornea is monitored during irradiation of the cornea to bring about corneal crosslinking. Because the change in ultrasonic response is correlated with the degree of crosslinking achieved, a desired degree of crosslinking can be achieved by terminating the irradiation when the change reaches a threshold. The change in ultrasonic response can be determined by taking a baseline measurement before irradiation and additional measurements during irradiation using the same ultrasonic transducer (47). The transducers may be carried on a device (30) resembling a contact lens which overlies the eye and which transmits the light used in the irradiation step to the eye.

  • Patent number: 8974444
    Abstract: A method for welding tissue wounds in an animal. The method comprises joining edges of a tissue wound and irradiating the tissue wound and tissue surrounding the tissue wound with a pulsed laser. The pulsed laser has a laser wavelength in a range of an absorption band of water, elastin and/or collagen in the tissue wound and tissue surrounding the tissue wound. The pulsed laser has a pulse width of not more than picoseconds in order of magnitude to heat tissue surrounding the tissue wound and facilitate bonding of native tissue protein present in the tissue surrounding the tissue wound to achieve tissue repair. The laser wavelength is in a range of between about 800 nm to about 2,700 nm.

  • Patent number: 8971997
    Abstract: An infrared fiber-optic device is able to monitor esophageal temperature during an ablation/cryoablation procedure over a volume of interest to sense whether the temperature is too high or too low. The device may include a plurality of optical fibers each with a wide angle lens collectively disposed circumferentially and longitudinally to cover the volume of interest, as the particular region over which undesirable temperature may not be known beforehand. In other examples, the device may include an embedded array of infrared sensors extending sufficiently to encompass a volume of interest. The device may be used as part of a feedback control to regulate and stop operation of the ablation/cryoablation procedure to prevent vessel damage.

  • Patent number: 8951296
    Abstract: Devices and methods for therapeutic photodynamic modulation of neural function in a human. One embodiment of a method in accordance with the technology includes administering a photosensitizer to a human, wherein the photosensitizer preferentially accumulates at nerves proximate a blood vessel compared to non-neural tissue of the blood vessel. The method can further include irradiating the photosensitizer using a radiation emitter positioned within the human, wherein the radiation has a wavelength that causes the photosensitizer to react and alter at least a portion of the nerves thereby providing a therapeutic reduction in sympathetic neural activity. Several embodiments of the technology are useful for disrupting renal nerves, such as renal denervation, for treating hypertension, diabetes, congestive heart failure, and other indications.

  • Patent number: 8950406
    Abstract: Methods and apparatus for damaging hair follicles using a series of rapidly-delivered low-fluence pulses of coherent or incoherent light are disclosed herein. In some embodiments, the pulses of coherent or incoherent light have a wavelength or wavelengths primarily in the range between 750 nm and 1500 nm. In some embodiments, applied electromagnetic radiation comprising the rapidly-delivered low-fluence pulses is effective for concomitantly heating both the sub-dermal layer (i.e. the dermis) of the tissue and the hair follicles. In some embodiments, the thermal damaging of the hair follicles is useful for facilitating hair-removal.

  • Patent number: 8932338
    Abstract: A noninvasive method of reducing fat from targeted regions of a patient's body by applying low-level laser energy externally through the skin of the patient to the targeted areas. Sufficient laser energy is applied to release at least a portion of intracellular fat into the interstitial space. The released intracellular fat is removed from the body through the body's natural functions. The preferred embodiment uses laser energy at about 635 nm.

In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material. Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.

  • Publication number: 20150005751
    Abstract: A method and device for cosmetic surgery, especially fat reduction and collagen reformation, by means of a high power laser operating at about 980 nm is presented. The cosmetic surgery method substantially reduces or removes localized lipodystrophies, and essentially reduces flaccidity by localized laser heating of adipose tissue using an optical fiber inserted into a treatment area. The method and device are particularly well suited for treating Lipodystrophies with flaccidity High power laser energy is applied to “fat” cells to breakdown the cell walls releasing the cell fluid. The laser radiation is applied through an optical fiber which is held within a catheter-like device having a single lumen. Traditionally difficult fat cells are treated well. Delicate areas are treated safely. A saline solution may also be inserted into the treatment site to aid in the heating of the fat cells and their eventual destruction as well as their removal.
