  • Methods and devices for minim ally-invasive delivery of radiation to the eye
    Patent number: 10850118
    Abstract: Methods and devices for minimally-invasive delivery of radiation to the eye (such as the posterior portion of the eye) including cannula systems with multiple treatment positions and/or multiple channels in the distal tip of the cannula systems. The channels can accommodate emanating sources and exposing a target at various treatment positions. The emanating sources may be annulus-shaped.
    Type: Grant
    Filed: January 15, 2018
    Date of Patent: December 1, 2020
    Assignee: SALUTARIS MEDICAL DEVICES, INC.
    Inventors: Wendell Lutz, Russell J. Hamilton, Thomas C. Cetas, Laurence J. Marsteller, Timothy Shriver, Samuel S. Hyman

  • Birefringent crystal thermometer
    Patent number: 4140393
    Abstract: This invention relates to the use of a birefringent crystal as the sensing element in a probe thermometer constructed of certain basic optical components utilized in three separate modes. Thus, all of the modes of the invention are directed to a probe thermometer which uses the temperature dependence of the birefringence of certain single crystals as the temperature sensitive parameter. One such crystal is a Y-cut single crystal of LiTaO.sub.3. Alternative crystals having adequate sensitivity in the desired temperature range may be constructed from LiNbO.sub.3 or BaTiO.sub.3. Polarized light propagates through the crystal in two modes, the ordinary ray and the extraordinary ray, which have indices of refraction n.sup.o and n.sup.e. For LiTaO.sub.3 at room temperature, n = 2.2, B = n.sup.e - n.sup.o = 0.004, and dB/dT = 4.4 .times. 10.sup.-5 /.degree. C.
