  • Patent number: 9421092
    Abstract: An intraocular lens injector cartridge assembly contains a pre-loaded lens and an integral lens-contacting plunger rod. Configured for removably mating with an injector handpiece, the cartridge assembly is suitable for use with either manual or automated injector systems. The injector cartridge assembly includes a tubular body having a longitudinal bore extending between a distal end and a proximal end, an IOL disposed within said longitudinal bore, and a lens-contacting plunger rod retained within said bore, between the IOL and the proximal end of the tubular body. The lens-contacting plunger rod is configured for translation along the longitudinal bore upon engagement by an injector rod introduced by the injector handpiece into the proximal end of the tubular body, so that the IOL is folded and ejected from the distal end of the tubular body by the translation of the lens-contacting plunger rod.

  • Patent number: 8721600
    Abstract: A delivery gun for discharging bone cement from a cartridge that includes a piston. The gun has a casing from which a drive rod and a disk extend. A drive assembly advances the drive rod and disk so that disk displaces the piston causing the discharge of cement. The drive assembly includes plural links that are pivotally connected to a trigger. The links are displaced in response to the manual displacement of a trigger. One of the links is configured to selectively engage the drive rod. When this particular link is engaged with the drive rod and displaced, the drive rod the drive rod is advanced at a first speed. When this link does not is not engaged with the drive rod, the drive rod is advanced by another link at a second speed.

  • Patent number: 8353622
    Abstract: A cartridge in which bone cement is mixed and from which the cement is discharged. A blade with plural vanes is disposed in the cartridge for mixing the cement. A piston located in one end of the cartridge is actuated to push the mixed cement out of the cartridge. The blade has plural vanes, one for scraping cement off the side of the cartridge, one for scraping cement off the piston and one for scraping cement off the end of the cartridge opposite the end in which the piston is normally located. The blade is collapsible so that when the piston is actuated the blade compresses to allow the cement in the cartridge to be pushed out.

  • Patent number: 7752682
    Abstract: A personal protection system is mountable to a user for distributing air to the user includes a shell providing structure. A fan module is supported by the shell for generating a flow of air. Cushioning is provided between the fan module and the shell to reduce vibrations and noise. The fan module includes a fan with blades having an airfoil shape for added noise reduction. An air flow channel is in fluid communication with the fan module for routing the flow of air. A pair of nozzle tips are in fluid communication with the air flow channel and are rotatably adjustable to allow directional adjustment of the flow of air toward a neck of the user. The personal protection system also includes a face shield with multiple removable layers which are sterilized as a unit using gamma radiation.

  • Publication number: 20040267272
    Abstract: A bone cement mixing and delivery system is provided. The system includes a mixing cartridge for receiving liquid and powder components of bone cement, a mixing device for mixing the components, and a delivery gun for discharging the bone cement from the mixing cartridge. The mixing cartridge comprises a cylinder having proximal and distal ends with a cylinder wall extending between the ends. A piston is locked at the distal end by a locking member that includes a pair of locking tabs protruding into slots in the cylinder wall. With the piston in the locked position, the mixing device, e.g., a mixing shaft and blade, mixes the components. After mixing, the cartridge is placed in the delivery gun and release buttons on the locking member are engaged by a release mechanism on the delivery gun to release the piston from the locked position.
