A fluid displacement and pressurization device which provides both a substantial amount of thread engagement as well as provides for single hand control for all operational manipulations including maintaining a set fill volume, rapid filling and displacement, and pressurization and retention of evacuation positioning during balloon depressurization. The device allows for the use of one hand to not only transition the device from micro-movement control to macro-movement control, but also regarding rotating, pushing or pulling the handle of the plunger.

Actuating mechanism for fluid displacement and pressurizing devices

A fluid displacement and pressurizing device which includes a housing, a first piston in the housing, a plunger which extends from the housing and has a second piston thereon, and an actuator that works to selectively lock the piston to either the housing or the plunger depending on the position of the second piston in the housing. Effectively, the actuator includes a first locking mechanism that locks and unlocks the first piston relative to the housing and a second locking mechanism that locks and unlocks the plunger relative to the piston. As such, the first locking mechanism is not only a locking mechanism but is also an actuating mechanism with regard to actuating the second locking mechanism.

Advanced actuating mechanism and method of operation for fluid displacement and pressurizing device

A pressure gauge attachment system includes a thread having a thread stop as well as at least one engagement element that is configured to defect during installation and effectively provide an interlock after installation. The system is suited for rapid and simplified installation, inherently provides automatic orientation of a pressure indicator, enhanced sustainability, flexibility in manufacturing, as well as provides a secure, reliable fluid-tight sealed connection that does not rely upon a pipe thread, additional couplings or clamping nuts for retention.

Pressure guage attachment system and method of assembly

An IOL delivery device which has a macro movement actuator which is actuateable to move an IOL into position in the device for the IOL to be delivered, and a micro movement actuator comprising at least one pivotable member which is pivotable to deliver the IOL to the eye. The pivotable member may comprise one or more wheels that are rotatable using one's finger.

Intraocular lens delivery device and method of use

An IOL delivery device which has a macro movement actuator which is actuatable to move an IOL into position in the device for the IOL to be delivered, and a micro movement actuator which is actuatable to deliver the IOL to the eye.

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.
