Patent number: 11771593Abstract: A gas mixture apparatus includes a measurement control system, an activation system, a pressurized chamber with one or more gases, and a mixing chamber. A filter can be preattached to an outlet of the mixture apparatus, allowing excess gas to be discharged therethrough and then atmospheric air to be drawn into the mixture apparatus through the filter for creating a therapeutic gas mixture.Type: GrantFiled: December 6, 2021Date of Patent: October 3, 2023Assignee: Alcon Inc.Inventors: Jack Robert Auld, James Lescoulie, John Christopher Huculak, Marcus Antonio Souza, Christopher McCollam

Patent number: 11622885Abstract: A vitrector that includes an adjustable illumination aperture is described. The vitrector may include a probe and a light sleeve assembly extending along and substantially surrounding the probe. The light sleeve assembly may include a plurality of optical fibers. At least a portion of the optical fibers are operable to provide illumination so as to define an illumination aperture about the vitrectomy probe. A portion of the optical fibers may be encapsulated. The light sleeve assembly may be adjustable along a length of the probe, providing adjustment of the illumination aperture to increase or decrease an area of illumination provided thereby.Type: GrantFiled: May 20, 2019Date of Patent: April 11, 2023Assignee: Alcon Inc.Inventors: Jon-Peter Meckel, Matthew Edward Bazydlo, Christopher McCollam

Patent number: 10085883Abstract: An articulating optical surgical probe includes a handle sized to fit in a single hand and a single rigid cannula extending from the handle having a diameter of 20 Ga or less. The probe further includes a slotted tip at a distal end of the cannula and at least one optical fiber extending through the handle, the single rigid cannula and the slotted tip, and a pull-wire secured to the slotted tip. When the pull-wire exerts tension on the slotted tip, the slotted tip will deviate from straight to a bend angle controlled by the tension in the pull-wire. The slotted tip is formed from a resilient material that will restore to the straight position when the tension exerted by the pull-wire is released.Type: GrantFiled: October 18, 2017Date of Patent: October 2, 2018Assignee: Alcon Research, Ltd.Inventors: Jack Robert Auld, Christopher McCollam, Xiaoyu Yu

Patent number: 7783346Abstract: A transparent illuminated infusion cannula is provided for illuminating an area during eye surgery. An optical fiber may be spaced a certain distance away from the cannula such that fluid flow around the distal end of the fiber and into the transparent cannula may occur with a much higher flow rate than what had previously been possible. The fiber cannula airspace may be optimized so that the cross-sectional area of the fluid conduit remains substantially constant in order to achieve a best compromise between high light transmittance and high fluid flow rate.Type: GrantFiled: December 18, 2006Date of Patent: August 24, 2010Assignee: Alcon, Inc.Inventors: Ronald T. Smith, Jack R. Auld, Christopher McCollam, Dean Y. Lin, Dyson Hickingbotham
