  • Patent number: 10182906
    Abstract: An intraocular lens inserter can include an energy storage portion, an actuator portion that provides temperature compensation, and a lens support portion. The energy storage portion can include a compressible energy storage device, such as a compressible fluid, springs, and other devices. The inserter can include an actuator portion operating with a substantially incompressible fluid. The actuator can be configured to provide an operator with control over the release of pressurized fluid so as to move a plunger for the discharge of a lens from an intraocular lens cartridge, discharge of the lens being limited based at least in part on pressure feedback from the pressurized fluid due temperature increases.

  • Patent number: 10029052
    Abstract: A self-contained apparatus and corresponding methods are provided for delivering viscous fluids in a controlled manner, such as delivering a viscous fluid in a surgical setting. The self-contained apparatus can include a motion following pressure regulator that allows for linear control of a regulated pressure. The regulated pressure can be used for dispensing a viscous fluid from a syringe that is coupled to the self-contained apparatus. The pressure regulator regulates a pressure derived from a pressurized fluid reservoir located at least partially within a housing of the apparatus. This allows the viscous fluid to be delivered using pressure to provide a driving force greater than a force easily delivered manually, while still allowing a surgeon to retain fine control over the rate of viscous fluid delivery.

  • Patent number: 10010408
    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.

  • Publication number: 20170325995
    Abstract: A gas mixture apparatus includes a measurement control system, an activation system, a pressurized chamber with one or more gases, and a mixing chamber. The apparatus can also include additional pressure regulation control systems. The gas mixture apparatus can be used to introduce and automatically perform the steps to achieve a desired concentration of the one or more gases contained in the pressurized chamber. The gas mixture apparatus can include the pressurized chamber within the apparatus itself such that no external devices are necessary for introducing the one or more gases into the mixing chamber.

  • Publication number: 20170312422
    Abstract: Devices and methods are provided for delivering fluid into a patient's body. In an exemplary embodiment, the device may include a syringe cartridge and a syringe driver that may be coupled to the cartridge. The cartridge may include a housing including a proximal end, a distal end, and defining an interior, the cartridge further including a piston slidably disposed within the interior for delivering fluid within the interior through a port in the distal end. The driver may include a plunger for advancing the piston within the interior of the housing, a source of pressurized fluid, a valve, and an actuator member coupled to the valve for selectively opening a flow path from the source to the plunger to control flow of the pressurized fluid to advance the plunger to deliver fluid from the interior of the housing at a desired rate.

  • Patent number: 9764088
    Abstract: Systems and methods are provided for filling syringes, e.g., for use during pneumatic retinopexy or other medical procedures. In one embodiment, the system includes a housing carrying a gas canister including an outlet communicating with a fluid path extending from the outlet to a syringe cavity. A syringe includes a barrel receivable in the syringe cavity such that a port of the barrel communicates with the fluid path. An actuator is provided on the housing for selectively opening the outlet of the gas canister to deliver gas therein along the fluid path into the interior of the barrel, thereby causing the plunger to move from a distal position to a proximal position.

  • Patent number: 9505505
    Abstract: An ophthalmic surgical system for filling a syringe with a retinal tamponading gas is disclosed. The system includes a surgical console having a user interface, a computer, first and second bottles containing pressurized retinal tamponading gases, and a port for fluidly coupling to an automatic gas filling consumable including a syringe. A user selects a particular retinal tamponading gas via the user interface, and the system fills the syringe.

  • Patent number: 8688401
    Abstract: In certain embodiments, determining an endoilluminator output includes calculating an illuminator contribution of an endoilluminator system and a fiber contribution of one or more optical fibers of the endoilluminator system. The endoilluminator output is determined from the illuminator contribution and the fiber contribution. The illuminator contribution may be established using calibrated or empirically determined factors, such as an illuminator leg efficiency, an attenuator factor, an initial lamp performance, and/or a lamp performance degradation factor of the lamp. The fiber contribution may be established using calibrated or empirically determined factors, such as a fiber coupling factor and/or fiber transmission ratio of the optical fibers.
