  • Publication number: 20230277126
    Abstract: Systems and relative method of monitoring the state of a subject’s retinal disease employ remote based OCT imaging of a subject’s retina. A method includes receiving optical coherence tomography (OCT) image data of a retina of a subject for each of a series of OCT imaging sessions of the retina. The OCT image data of the retina is processed to determine a series of measured extent values. Each of the one or more measured extent values is indicative of a respective extent of the retinal disease.

  • Patent number: 10653482
    Abstract: A method for photoselective vaporization of prostate 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/cm2, in a spot size of at least 0.05 mm2.

  • Patent number: 9277853
    Abstract: An endoscope for an optical fiber provides for inflow and outflow of irrigant. A telescope is included having a field of view directed into a working region. The endoscope defines a “hooded region” with an extended, blunt tip. The optical fiber fits within the endoscope has a side or end firing tip with an emission surface. A guide element is adapted to movably support the optical fiber in a position spaced away from the working region, and limit lateral movement of the tip without preventing longitudinal and rotational movement. An irrigant flow arrangement operates to direct inflowing irrigant over the emission surface of the tip. The fiber is assembled with a fiber coupler, a handle, a fiber port cap, and a travel limiter fixed to the fiber at a predetermined distance from the tip. The travel limiter cooperates with the endoscope and the fiber port cap to limit longitudinal and rotational movement of the fiber.

  • Publication number: 20120277735
    Abstract: Laser radiation delivered to a treatment area may be used with a smoke suppressing irrigant. A laparoscopic laser device may include an elongate body adapted for insertion into an insufflated bodily cavity. A laser energy delivery element, at the distal end of the elongate body, may be coupleable to a source of tissue-vaporization-capable laser energy and capable of delivering laser energy along a laser energy path extending away from the laser energy delivery element. A smoke-suppressing liquid may be directed generally along the laser energy path. A remote visualization device may be used to view along the laser energy path. The laser energy path can be shrouded with a circumferentially extending suction manifold so that liquid can be suctioned from the target site and away from the laser energy path. In some examples, the suction manifold is an axially extendable and contractible suction manifold.

  • Publication number: 20080287936
    Abstract: A medical laser system having a telescope and a laser unit, wherein the laser unit includes an optical fiber for performing medical surgical procedures, and a telescope designed to view a target area during the medical procedure and to illuminate the target area. The telescope includes a tubular case, an optical train, an integrated optical filter, and an optical fiber to provide illumination. The telescope can be connected to a camera to allow for viewing the target area on a monitor. Alternatively, the telescope can end in an eyepiece. The integrated optical filter blocks a selected laser light wavelength such that the laser light does not overexpose or damage the camera. The integrated optical filter can include an integrated flat filter or integrated coated lens.
