20080255577 | Lens Delivery System Cartridge and Method of Manufacture - A cartridge for an IOL delivery system that has a straight thinned walled distal nozzle. The transition region between the tapered folding portion of the cartridge and the nozzle contain reinforcing gussets to help prevent splitting of the cartridge. Flow leaders in the nozzle direct the flow of material during molding at the 12:00 o'clock position, positioning the weld line of the flow front at the 6:00 o'clock position. | 10-16-2008 |
20080312661 | Lens Injector Lumen Tip for Wound Assisted Delivery - A cartridge for an IOL delivery system that is specifically designed to aid in wound assisted IOL delivery. The distal tip of the nozzle has an extended canopy which serves to open the incision and support the IOL. Peripheral protrusions, flanges, or stops extending laterally from the side of the distal tip provide a positive depth limitation, and prevent the full insertion of the nozzle into the incision. In addition, the protrusion provides support to the incision to reduce the tendency of wound damage through tearing. | 12-18-2008 |
20090112223 | Lens Delivery System - A lens delivery system handpiece having a threaded plunger rod with a ball lock ring.

20100204705 | Automated Intraocular Lens Injector Device - 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. | 08-12-2010 |
20100305577 | INTRAOCULAR LENS DELIVERY SYSTEM WITH A DISPOSABLE PLUNGER SEGMENT AND METHOD OF USE THEREFOR - The present invention is directed to an intraocular lens delivery system with a multi-segment plunger.

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. | 05-22-2014 |
20140303637 | AUTOMATED INTRAOCULAR LENS INJECTOR DEVICE - An IOL injection device comprises a tubular housing with a plunger longitudinally disposed within the tubular housing. The device is configured so that when the plunger is translated towards the front of the device, its tip engages an intraocular lens insertion cartridge mounted at or near the front end of the housing. The IOL injection device further comprises a control circuit. The control circuit is configured to perform the steps of advancing the plunger to a critical point at which an axial compressive force on the lens suddenly increases, retracting the plunger from the critical point to a sufficient distance for material of the intraocular lens to relax, pausing to allow the material of the intraocular lens to relax, advancing the plunger to the critical point a second time, and continuing to advance the plunger beyond the critical point to implant the intraocular lens. | 10-09-2014 |
