Patent number: 11491050Abstract: Methods and systems for performing an ophthalmic surgical treatment procedure include one or more wicking members to secure a volume of treatment fluid to a distal end of a surgical instrument. Such a surgical instrument may include an elongate tubular member having a proximal end, a distal end, and a lumen extending therebetween, the elongate tubular member being configured to penetrate a body cavity of a patient. The instrument may further include a wicking member extending beyond the distal end of the elongate tubular member. The wicking member may be configured to secure a volume of treatment fluid delivered through the lumen to the wicking member for application from the wicking member to target tissue in the body cavity.Type: GrantFiled: November 6, 2019Date of Patent: November 8, 2022Assignee: Alcon Inc.Inventors: Nicholas Max Gunn, Andrew David Johnson, Pooria Sharif Kashani

Patent number: 10758411Abstract: A handheld reciprocating surgical tool may contain an inertial damper to counteract the momentum of a diaphragm assembly of the reciprocating surgical tool. A momentum of the inertial damper may be tuned such that the momentum of the inertial damper is comparable in magnitude and opposite in direction to a momentum of the diaphragm assembly. The diaphragm assembly may include a cutting tool. The combined momentum of a diaphragm assembly and the inertial damper may result in a reduced net momentum, which may reduce vibration of the reciprocating surgical tool haptically experienced by a surgeon, thereby improving surgeon comfort.Type: GrantFiled: February 6, 2018Date of Patent: September 1, 2020Assignee: Alcon Inc.Inventors: Joshua Dean, Nicholas Max Gunn, Andrew David Johnson

Publication number: 20170165109Abstract: Systems, apparatuses, and methods of and for an ophthalmic surgical system are disclosed. In an exemplary implementation, an ophthalmic surgical system includes a patch sized and shaped to seal a retinal break of an eye by preventing fluid from infiltrating a sub-retinal space when adhered to the retina surrounding the retinal break; and a delivery device including a cannula configured to maintain the patch in a furled state for passage through an incision in the eye, the delivery device actuatable to deploy the patch within a vitreous chamber of the eye. In another exemplary implementation, an ophthalmic surgical method includes damaging tissue around a retinal break; delivering, into the vitreous chamber, a patch sized and shaped to seal the retinal break; positioning the patch on the retina surrounding the retinal break; and affixing the patch to the retina such that the patch prevents fluid from infiltrating a sub-retinal space.Type: ApplicationFiled: December 8, 2016Publication date: June 15, 2017Inventors: Nicholas Max Gunn, Pooria Sharif Kashani, Michael J.

Patent number: 9492321Abstract: A microfluidic valve for implantation in an eye of a patient is disclosed. The valve may include a chamber formed between a substrate and a flexible membrane. The valve may also include a boss disposed in the chamber and having a top edge in selective contact with the flexible membrane. The top edge includes a relief portion and a non-relief portion, with the relief portion being structurally arranged so that a pressure required to separate the membrane from the relief portion is less than a pressure required to separate the membrane from the non-relief portion. The valve also may include an inlet extending through the boss and the substrate through which fluid enters the chamber and an outlet configured to allow fluid to exit the chamber. Methods for priming a microfluidic valve are also disclosed.Type: GrantFiled: February 10, 2015Date of Patent: November 15, 2016Assignee: Novartis AGInventors: Nicholas Max Gunn, Andrew David Johnson
