Abstract: Intraocular lens inserters and methods of use are disclosed. An example intraocular lens inserter may include an interior assembly having a movable member disposed therein. The movable member is movable in response to a pressure of a compressed gas. In response to the pressure of the compressed gas, the moveable member pressurizes a substantially incompressible fluid. The pressurized substantially incompressible fluid is used to advance a plunger. The plunger advances an intraocular lens through a lumen for insertion into an eye.

Abstract: An intraocular lens inserter can include a drive device with controllable advance motion. The drive device may include an actuator device and an energy device. The actuator device may include a piston rod that uses the advance motion to push an intraocular lens from a cartridge for insertion into an eye of an animal. The energy device may act upon the actuator device to generate the advance motion. The actuator device may include a dampening medium to control the advance motion, such as by controllably dampening the advance motion.

Abstract: An enhanced flow ophthalmic surgical probe for ophthalmic microsurgery, such as vitrectomy, in an eye of a patient is disclosed. The enhanced flow probe includes a body, a needle, a cutter, and an optional stiffening sleeve. The needle, the cutter, and the optional stiffening sleeve each possess a widened diameter at its proximal portion relative to the diameter at its distal portion, thereby providing an enhanced ophthalmic surgical probe that allows adequate stiffness, reduced flow resistance, and an increased flow rate while maintaining a less invasive, large gauge diameter needle and cutter.

Abstract: A system for separating fluid components comprising a sealless rotating drum, a rotatable disposable centrifuge cartridge within the drum, a multi-lumen tube fluidly connectable to the cartridge and to an external fluid source, and a control system capable of independently controlling the flow rate within each lumen of the multi-lumen tube. This system may also be used in apheresis procedures for separating blood components from whole blood. The multi-lumen tube may have a ribbon section that unidirectionally fits within a peristaltic block of rollers, wherein each lumen's flow rate may be individually controlled. The system may further include a camera unit operable to observe a separation boundary within the centrifuge cartridge and accordingly adjust the rotation speed to increase or decrease the amount of separation.
