Abstract: An intraocular lens inserter for use during cataract surgery for delivering an intraocular lens (IOL) loaded into an IOL cartridge into a patient's eye. The inserter comprises an outer shell housing containing a hydraulic housing. A hydraulic piston positioned within the hydraulic housing defines an annular hydraulic chamber. The hydraulic chamber is filled with a fluid via a fill port. A high pressure compression spring constantly urges the piston forwardly to pressurize the fluid in the hydraulic chamber. During use, a valve element operatively connected to a depressible operation button, controls bleeding of fluid from the hydraulic chamber, whereupon the forward tip of the piston is moved forwardly to mechanically deliver the intraocular lens from the IOL cartridge into the patient's eye.

Abstract: A clamp for flexible tubing such as medical tubing or micro-tubing. The clamp comprises a clam-shell design having lateral non-opposing sidewalls that prevent the micro-tubing from bending out from under the mating clamping anvils when closed. The lateral non-opposing sidewalls of the clamp are non-opposing in order to facilitate injection molded in two halves of an injection mold without the use of additional slides.

Abstract: A high flow rate inflator intended to be threaded into or onto the threaded neck of a conventional gas cylinder. The inflator comprises a spring-loaded ballasted firing pin that is retained in a cocked position by a tethered trigger pin. Upon firing by pulling on the trigger pin, the firing pin forcibly moves into engagement with a power primer mounted with a power primer holder to ignite the same, whereupon the ignition gases forcibly drives a hollow larger diameter pierce pin mounted within an interior cylinder into the frangible seal of the gas cartridge to cut a large-bore hole therethrough and allow gas escaping from the gas cylinder to flow at a high rate through the inflator into an inflatable device.

Abstract: An indicator to be snapped onto an inflator to indicate the “ready” operating condition of the inflator and, upon firing of the inflator by jerking the jerk handle to pivot the firing lever, the firing lever pops off the indicator from the inflator, thereby indicating the “fired” inoperable operating condition.

Abstract: A check valve including an elastomeric valve element having a dome-shaped configuration that seals in its at-rest position occluding fluid flow in both directions. The dome-shaped elastomeric valve element is constructed in such a way to be deflectable, such as being activated by the external device such as a male luer whereupon the valve is cracked open to become a two-way valve allowing flow in both directions. The valve element may also be cracked open by sufficient fluid pressure in its inlet. The valve element is self-aligning. The dome-shaped of the valve element includes cut-outs for additional fluid flow, thereby streamlining flow while reducing the potential for air entrapment. The underside of the dome-shaped valve element also includes a thickened concave undersurface and thickened support legs to significantly increase the resistance to high backpressures, while also minimizing potential air entrapment.

Abstract: A luer medical connector having a male luer body for connection with a female luer assembly which includes a female luer body, a fluid channel insert within the female luer body, an elastomeric seal between the female luer body and the male luer body, and an elastomeric stopper at a proximal end of the female luer body.

Abstract: A male reflux valve comprising a distal body portion and a proximal body portion, the proximal body portion having a male connection for connection to a female connection of an access device, a valve element operatively positioned within the distal body portion, a core operatively positioned within the distal body portion to retain the valve element into sealing engagement with the distal body portion and an actuator reciprocably retained within a generally circular cylindrical longitudinal bore of the proximal body portion in engagement with the valve element to open the valve element when engaged by the female connection of the access device.

Abstract: A relief valve having a crenelated exhaust ring surrounding the poppet. The crenelated exhaust ring comprises a series of alternating crenels and merlons which together define an increasing cross-sectional exhaust area circumferentially about the poppet during cracking (i.e., once the pressure in the inflatable device exceeds the cracking pressure) as the poppet rises in the relief valve in response to increased pressures and, conversely, a decreasing cross-sectional exhaust area about the poppet during closing as the poppet lowers to its re-seated, sealed position. The design of the crenels in the form of a larger upper cross-sectional area to a smaller lower cross-sectional opening, advantageously achieves a reseating pressure that is substantially equal to or slightly less than the cracking pressure while minimizing possible oscillations during re-seating of the poppet.

Abstract: A male reflux valve comprising a distal body portion and a proximal body portion, the proximal body portion having a male connection for connection to a female connection of an access device, a valve element operatively positioned within the distal body portion, a core operatively positioned within the distal body portion to retain the valve element into sealing engagement with the distal body portion and an actuator reciprocably retained within a generally circular cylindrical longitudinal bore of the proximal body portion in engagement with the valve element to open the valve element when engaged by the female connection of the access device.
