Patent number: 10668191Abstract: Devices, systems, and methods for treatment of an eye alter aspiration flow from the eye in response to an occlusion of the aspiration conduit pathway. Where aspiration is drawn from the eye using a volumetric pump, the pump can be reversed so as to induce fluid reflux from the aspiration conduit pathway into the eye to help clear the occlusion. The pump may vary the reverse flow in response to sensed aspiration pressure or the like, and the reverse flow may be halted before the pressure within the aspiration conduit pathway adjacent the eye significantly exceeds the irrigation fluid pressure and/or the pressure within the eye. Reflux may alternatively be generated by modulating a vent valve disposed between an irrigation conduit pathway and the aspiration conduit pathway.Type: GrantFiled: June 18, 2018Date of Patent: June 2, 2020Assignee: Johnson & Johnson Surgical Vision, Inc.Inventors: David King, John I. Muri, Thomas B. Sutton

Patent number: 9295765Abstract: The present invention is generally directed to improved methods, devices, and systems for controlling surgical fluid flows, particularly during treatment of an eye. In many embodiments, the invention provides 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. The multiple types of cassettes may be produced using a common cassette frame and may include a visual indication of functionality.Type: GrantFiled: November 9, 2006Date of Patent: March 29, 2016Assignee: Abbott Medical Optics Inc.Inventors: John I. Muri, Craig Edwards, Thomas B. Sutton

Patent number: 8241242Abstract: A device for achieving high vacuum stability during phacoemulsification surgery includes a main aspiration line connected to a vacuum source which enables a fluid flow from a phacoemulsification handpiece tip to a drainage reservoir. A first tubing segment is provided in the main aspiration line along with a second tubing segment generally parallel to the first tubing section and a valve disposed in the second tubing segment regulates fluid flow through the second tubing segment in order to limit vacuum surge in the main aspiration line upon clearing of an occlusion in the phacoemulsification handpiece tip.Type: GrantFiled: March 30, 2005Date of Patent: August 14, 2012Assignee: Abbott Medical Optics Inc.Inventor: Thomas B.
