Patent number: 9839738Abstract: In various embodiments, a cannula device includes an irrigation handpiece portion (with a first aspiration tip for aspiration and an irrigation fluid outlet for irrigation) and an aspiration handpiece portion (configured to aspirate fluid into a second aspiration tip that extends from a distal end of the aspiration handpiece portion). The cannula device is transformable between: (a) a coaxial mode in which the aspiration handpiece portion is coupled to the irrigation handpiece portion such that fluid is aspirated through the first aspiration tip and then the second aspiration tip in series and irrigation fluid is provided through the irrigation fluid outlet, and (b) a bimanual mode in which the aspiration handpiece portion is separated from the irrigation handpiece portion to provide aspiration through the second aspiration tip while the irrigation handpiece portion continues to provide irrigation fluid through the irrigation fluid outlet.Type: GrantFiled: May 8, 2014Date of Patent: December 12, 2017Assignee: Novartis AGInventors: Charles Kittridge Beauvais, G.

Publication number: 20080125712Abstract: An ophthalmic injection system is disclosed. The system has a dispensing member, a plunger, an actuation chamber, a lock mechanism, a lock stop, a port, a source of pressurized gas, and a shaft. The lock mechanism travels in the actuation chamber in an axial direction toward and away from a distal end of the dispensing member. The lock stop is located on the inner surface of the actuation chamber. The lock stop is engageable with the lock mechanism such that when the lock mechanism travels in the axial direction toward the distal end of the dispensing member to a first position located on a distal side of the lock stop, the lock mechanism cannot travel in a reverse direction away from the distal end of the dispensing member to a location on a proximal side of the lock stop.Type: ApplicationFiled: September 26, 2006Publication date: May 29, 2008Inventors: Bruno Dacquay, James Foster, Mark Hopkins, Lamar Kirchhevel, Cesario Dos Santos, Salomon Valencia

Publication number: 20080097379Abstract: A method is disclosed for delivering a quantity of a substance into an eye. By applying compressed gas into an actuation chamber, a separating member connected to a lock mechanism and a plunger is displaced. The plunger displaces the quantity of the substance from a dispensing member and into an eye. The plunger is retained in an extended position so that the quantity of the substance is not retracted back into the dispensing member when the dispensing member is removed from the eye.Type: ApplicationFiled: September 26, 2006Publication date: April 24, 2008Inventors: Bruno Dacquay, James Foster, Mark Hopkins, Lamar Kirchhevel, Cesario Dos Santos, Salomon Valencia
