Patent number: 11065153Abstract: Methods, devices, and systems for laser eye surgery generally make use of a console that interchangeably accepts multiple types of eye treatment cassettes. The cassettes enable one or both of displacement-based or vacuum-based aspiration. The console and the cassette may communicate to establish the functionality of the installed cassette by utilizing a component indigenous to the operation of the cassette. A dual-mode cassette may include a separable holding tank for enabling vacuum-based aspiration. A displacement-based pump may be provided to drain the holding tank while the vacuum system continues to aspirate fluids. A vacuum sensor for controlling the flow of aspirated fluids may have three ports for communicating with a handpiece, a displacement-based pump, a vacuum-based pump, or an irrigation source. The handpiece may be vented during vacuum-based aspiration by opening a vent valve interposed between the handpiece and the vacuum source.Type: GrantFiled: July 31, 2015Date of Patent: July 20, 2021Assignee: Johnson & Johnson Surgical Vision, Inc.Inventors: John I.

Patent number: 11015988Abstract: A method for providing a temperature sensitive element surrounding a surgical instrument to provide a visual indication of tip temperature to an operator of the instrument. Change in color of the element is an indication to the operator to be aware of the generated heat and reduce power to the instrument accordingly. When the tip of a surgical instrument heats up to a certain threshold that would cause harm, a reversible thermochromic property of the element may change colors in direct relation to the rise and fall of temperature.Type: GrantFiled: February 22, 2017Date of Patent: May 25, 2021Assignee: Johnson & Johnson Surgical Vision, Inc.Inventor: Chetan P. Nirkhe

Patent number: 11000368Abstract: This intraocular lens (IOL) injector cartridge has a proximal opening in a main body for receiving an IOL. The main body has a lumen that extends longitudinally to a distal end having an opening smaller than the IOL. Passage through the lumen compresses or rolls the IOL so that when the distal end is inserted through a small incision in the eye the IOL can be expelled into the capsular bag. The distal end of the cartridge is beveled with a leading tip in front of a trailing heel. The characteristics of the beveled end are such that damage to the IOL is reduced. The bevel may be straight or curved and includes a distal face defined by the thickness of the distal end between the lumen and an exterior surface. The distal face may be flush with the bevel or chamfered. An inner corner angle between the distal face and the lumen is ?60° to reduce the chance of scratching the IOL as it passes out of the distal opening.Type: GrantFiled: January 24, 2019Date of Patent: May 11, 2021Assignee: Johnson & Johnson Surgical Vision, Inc.Inventors: Jason H. Safabash, David W. Gaylord, Kevin Springer
