  • Patent number: 10238541
    Abstract: The procedures described herein may involve using one or more treatment beams to induce one or more therapeutic benefits. In some embodiments, a series of short duration light pulses may be delivered to ocular tissue at a plurality of target locations with a thermal relaxation time delay to limit the temperature rise of the target ocular tissue and thereby limit a thermal effect to only a desired portion of the ocular tissue. The thermal relaxation time delay may be roughly equivalent to a duration of a scan of the treatment beam between each of the target locations. Such procedures may be used to treat diabetic retinopathy, macular edema, and/or other conditions of the eye. The treatment beam may be delivered at each target location within a sufficiently short duration so as to produce a visual appearance of a treatment pattern on the ocular tissue of the patient's eye.

  • Publication number: 20180368927
    Abstract: A computer-implemented method for generating and displaying a graphical user interface (GUI) is disclosed. The method includes displaying, via the GUI, a real-time video received from a camera disposed within an ablation catheter. The method further includes displaying, via the GUI, a graphical representation of a plurality of electrodes of the ablation catheter.

  • Patent number: 9004780
    Abstract: An identification assembly for use with a fiber-optic connector includes a non-conducting over-nut, an electrical assembly disposed at the proximal end of the over-nut, and an RFID tag supported by the distal end of the over-nut. The over-nut is configured to surround and couple with the fiber-optic connector. The electrical assembly includes a first electrical contact configured to electrically connect to the fiber-optic connector, a second electrical contact configured for electrical engagement with a contact portion of a light source assembly, and one or more electrical components coupled between the first and second contacts and providing a defined electrical characteristic. The identification assembly enables identification using either electrical-characteristic based or RFID-based identification approaches.

  • Patent number: 7771417
    Abstract: A laser system that includes a diode pump source. A frequency doubled solid state visible laser is pumped by the diode pump source and produces a pulsed laser output with a train of pulses. Resources provide instructions for the creation of the pulsed output, with on and off times that provide for substantial confinement of thermal effects at a target site. This laser system results in tissue specific photoactivation (or TSP) without photocoagulation damage to any of the adjacent tissues and without causing full thickness retinal damage and the associated vision loss.
