Patent number: 11951040Abstract: An ophthalmic device including a cannula having a cannula distal end, a lumen, and one or more orifices coupled to the lumen is provided. The cannula is configured to deliver a fluid. A sleeve is disposed around the cannula and has a sleeve distal end. A handle is coupled to the sleeve and the cannula, the handle having an actuator. An internal mechanism is coupled to the actuator and is configured to pump the fluid. The internal mechanism includes an inlet port disposed on a handle proximal end, a drive member coupled to the actuator and a plunger coupled to the drive member. The ophthalmic device is configured to retain a volume of fluid and to be prevented from being re-primed after a predetermined number of actuator presses, wherein the retained volume of fluid is dispensed over an additional number of actuator pushes.Type: GrantFiled: May 18, 2022Date of Patent: April 9, 2024Assignee: NEW WORLD MEDICAL INC.Inventors: Malik Y.
