Publication number: 20240074902Abstract: Devices and methods are disclosed for improved followability in laser-based ocular procedures. In some embodiments, an ophthalmic instrument comprises a projection located at the distal end of the shaft or cannula, the projection having a distal surface in proximity to the distal end of the optical fiber, the distal surface adapted to be positioned facing the treatment area during use of the ophthalmic instrument. An example method includes delivering laser energy through an optical fiber to the treatment area, wherein the distal surface of the projection inhibits bubbles formed during the procedure from moving distally away from the distal end of the ophthalmic instrument.Type: ApplicationFiled: August 17, 2023Publication date: March 7, 2024Inventors: Francisco Javier Ochoa, John Morgan Bourne

Patent number: 11602586Abstract: Systems and methods for monitoring for an occlusion in an aspiration line during an ophthalmic surgical procedure. An ophthalmic surgical system may include a first aspiration pump located in a handpiece, a second aspiration pump located away from the handpiece such as in a console, and a pressure sensor located between the first aspiration pump and the second aspiration pump. The pressure sensor is adapted to monitor for an occlusion in the aspiration line upstream of the first aspiration pump. The second aspiration pump may be operated at the same flow rate as the first aspiration pump and/or to maintain a constant pressure between the second aspiration pump and the first aspiration pump. Systems and methods as disclosed allow for a handpiece pump located close to the working tip while providing reliable occlusion detection with a pressure sensor located away from the handpiece.Type: GrantFiled: October 5, 2020Date of Patent: March 14, 2023Assignee: Alcon Inc.Inventors: John Morgan Bourne, Raphael Gordon, Gary P.

Patent number: 10617562Abstract: Disclosed herein is an apparatus for insertion in an eye of a patient for aspirating material from the eye in the treatment of an ocular condition, the apparatus comprising a needle disposed at a distal end of the apparatus, an aspiration channel extending from a distal aperture of the needle to a proximal end of the apparatus, and an irrigation sleeve coaxially disposed about the needle. The aspiration channel comprises a proximal portion having a first diameter, a bypass portion having a second diameter and at least one bypass port, and a distal portion having a third diameter. The second diameter is larger than the first diameter. The irrigation sleeve and the needle form an annular irrigation passageway therebetween. The bypass port is shaped and configured to establish fluid communication between the irrigation passageway and the aspiration channel.Type: GrantFiled: February 13, 2017Date of Patent: April 14, 2020Assignee: Alcon Inc.Inventors: John Morgan Bourne, John Richard Carpenter

Patent number: 10537471Abstract: Apparatuses, systems, and method for hydraulic pumps are disclosed. Particularly, hydraulic pumps for ophthalmic surgical procedures are disclosed. Hydraulic pumps within the scope of the disclosure may include an aspiration pump. An example aspiration pump may include first and second hydraulic cylinders and a plurality of one-way valves that are operable to permit fluid flow into a first part of a hydraulic cylinder responsive to movement of a piston within the hydraulic cylinder in a first direction and operable to permit fluid to flow out of the hydraulic cylinder responsive to movement of the piston in a second direction opposite the first direction. The aspiration pump may be attached to a housing of a hand piece, or a portion of the aspiration pump may be received into the housing of the hand piece.Type: GrantFiled: August 28, 2014Date of Patent: January 21, 2020Assignee: Novartis AGInventors: John Morgan Bourne, Gary P.
