Patent number: 8876751Abstract: In various embodiments, a handpiece may include an irrigation line coupled to an adjacent line reservoir with a piston configured to move within the adjacent line reservoir to increase an irrigation pressure in the irrigation line near a surgical site. In some embodiments, a sensor may be used to detect an occlusion break in the aspiration line and information from the sensor may result in signaling an actuator to move the piston in response to the occlusion break detection to compensate for a vacuum pressure drop associated with the occlusion break. The handpiece may further include a purge bypass line between the irrigation line and the adjacent line reservoir to allow flow from the irrigation line to travel through the adjacent line reservoir to purge the adjacent line reservoir.Type: GrantFiled: August 6, 2009Date of Patent: November 4, 2014Assignee: Alcon Research, Ltd.Inventors: Bruno Dacquay, Robert J.

Patent number: 8118790Abstract: The present invention is an ophthalmic injection system with a limited reuse assembly and a tip segment. The tip segment is connectable to and removable from the limited reuse assembly. The tip segment includes a dispensing chamber, a plunger, and a housing. The dispensing chamber holds a quantity of a substance to be injected into an eye. The proximate end of the plunger has a first mechanical linkage interface. The limited reuse assembly of the ophthalmic injection system has a power source, a controller, a motor, a second mechanical linkage interface located on an end of the motor shaft; and a second housing. The first mechanical linkage interface is mateable with the second mechanical linkage interface such that when the tip segment is connected to the limited reuse assembly, the first mechanical linkage interface mates with the second mechanical linkage interface so that motion of the shaft results in motion of the plunger.Type: GrantFiled: October 9, 2007Date of Patent: February 21, 2012Assignee: Alcon Research, Ltd.Inventors: Bruno Dacquay, Casey Lind, Cesario Dos Santos, Paul R.
