Abstract: An intraocular lens inserter can include an energy storage portion, an actuator portion, 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, such as liquids or other noncompressible fluids. The actuator can be configured to provide an operator with control over the release of energy from the energy storage portion so as to move a plunger for the discharge of a lens from an intraocular lens cartridge.

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.

Abstract: Gas-powered fluid injection systems and methods are disclosed, e.g., for delivering fluids into a patient's body. An injection device comprises a driver housing which forms and/or encloses a gas pressure source, an actuation piston driven by the gas pressure source and a hydraulic fluid pressurized by movement of the actuation piston. The hydraulic fluid flows through an adjustable valve into a plunger lumen which pushes a plunger of a fluid dispensing device, such as a syringe, to dispense an injection fluid, such as a medicament. The injection device has a movable plunger sleeve which receives the plunger of the fluid dispensing device. The plunger sleeve is moved during the activation and de-activation of the injection device such that it relieves residual pressure in the fluid dispensing device thereby preventing the fluid dispensing device from continuing to dispense injection fluid after the injection device has been de-actuated.

Abstract: Devices and methods are provided for delivering an agent into a patient's body using an injection device that includes a drive module and an injector module coupled to the drive module. The drive module includes a canister and puncture mechanism in a first chamber, a plunger in a second chamber communicating with the first chamber, and an actuator that moves the puncture mechanism to cause a puncture pin thereon to penetrate a septum of the canister and cause the gas within the canister to flow through the first chamber around the canister, and into the second chamber. The injector module includes a piston slidably disposed within an agent chamber and coupled to the distal end of the plunger such that, when the plunger moves from a retracted position to an extended position, the piston is advanced within the agent chamber to deliver an agent therein into a patient's body.

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.

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.

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: 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.

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.

Abstract: Canisters are provided that include a cylindrical body and a cap welded to the body to define a cavity filled with carbon dioxide or other fluid. The canisters may be loaded into a medical device, e.g., to provide an energy source for operating the device. Methods for making such canisters are also provided.
