A hybrid power system for delivering an implant to an eye using hydraulic fluid flow or pressure. An implant may be stored, advanced, and delivered to an eye using hydraulic fluid stored in a sterile container through a hollow advancement plunger. The plunger may rigidly advance the implant to a sealed position in a first phase, and then the implant may be advanced into the eye via hydraulic pressure or fluid flow in a second phase. The power system may provide a first cell having a first power density and a second cell having a second power density, wherein the second power density is greater than the first power density. A controller may use the first cell during the first delivery phase and the second cell during the second delivery phase.

Hybrid power delivery for surgical implants

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. The helmet has a chin bar that extends forward of the face of the individual wearing the system. At least one manually actuated control for regulating one aspect of operation of the system is mounted to the chin bar. Sometimes the control is a button that is depressed to control the operation of a helmet mounted fan that draws air into the hood or toga. A microphone may also be mounted to the chin bar.

Surgical personal protection apparatus

A surgical protection system to define a barrier between the user and the external environment. The surgical protection system comprising a helmet assembly, a hood and a transparent face shield. The helmet including a shell, a face frame coupled to the shell, a static tab, a first fastener disposed on the face frame; and a fan mounted to the shell and configured to circulate air about the user. The hood may include a first material defining an opening. The shield may be formed from flexible material and disposed within the opening of the hood. The shield may further include a tab extending from a top portion of the shield and define an opening configured to receive the static tab of the helmet to align the shield to the helmet. The first fastener disposed on the face frame may be configured to facilitate removable attachment of the shield to the helmet.

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system may include a head unit over which surgical garment such as a hood or a toga may be suspended over. The surgical garment may include a sterile material and a shield configured to be disposed in front of the wearers face when disposed over the head unit. The shield may comprise an anti-reflective coating configured to reduce the glare observed by the individual through said shield. The head unit may comprises a light assembly that is disposed on the wearers side of the surgical garment, and an inner surface of said surgical garment may comprise a light reflective material configured to reduce the amount of light emitted from said light assembly that is reflected back toward the individual.

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. A microphone, an amplifier and a speaker are mounted to the helmet. Speech of the individual wearing the personal protection system is picked up by the microphone and amplified speech is broadcast by the speaker. The speaker is outwardly directed so as to broadcast the speech out through the hood or toga covering the helmet.

Intraocular lens delivery device

Medical/surgical personal protection system including a helmet, the helmet having a fan and a fan housing that are curved to curve around the head of the individual wearing the helmet

Medical/surgical personal protection system including a helmet, a hood and a speaker that broadcasts speech outside of the hood

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.

Automated intraocular lens injector device

Medical/surgical personal protection system including a helmet and a hood, the helmet having chin bar-mounted controls

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. The hood/toga has a transparent face shield that is flexible. A fastening assembly holds the face shield to the helmet so that, at the top of the face shield the shield has a relatively wide radius of curvature. Extending downwardly from the top of the face shield the radius of curvature of the shield becomes smaller. Providing the face shield with this geometry reduces the extent to which the person wearing the helmet and hood/toga of this invention is subjected to glare.

Medical/surgical personal protection system including a helmet, a hood and fastening system for holding the hood to the helmet so the radius of curvature of the hood face shield varies along the face shield

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.

Delivery gun for dispensing bone bement from a cartridge, the gun having a multi-link linkage and capable of dispensing the cement at different flow rates

An intraocular lens delivery system includes an injector body having a bore surrounded by an inner wall. The system further includes a plunger configured to fit within the bore. The system also includes a plurality of deflectable members connected to the plunger and configured to contact the inner wall and to be deflected when the plunger is inserted within the bore. The deflectable members center the shaft and, when inserted within the injector body, contribute to producing a predetermined force resisting advancement of the plunger when deflected in the bore.

Lens delivery system

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.

Cartridge from which bone cement is discharged, the cartridge having a removably coupled nozzle

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. Integral with the helmet is a ventilation fan. The helmet also includes a light assembly for illuminating the surgical field. The helmet includes a front nozzle from which air from the ventilation fan is discharged. The light assembly is mounted to the helmet and is located below the front nozzle. Air discharged from the front nozzle blows heat generated by the light assembly away from the light assembly. In some versions of the invention, the light assembly includes a control arm connected to the light assembly for pivoting the light assembly.
