| 20080200920 | Lens Delivery System - A lens delivery system having a plunger rod with a sliding block reinforcing member. The sliding block rides on and along with the plunger rod and helps to reinforce the plunger rod against bending or buckling during use. | 08-21-2008 |
| 20080221584 | Lens Delivery System - A lens delivery system delivery system having a plunger, an injector body and a nozzle portion connected to the injector body. A sliding gate is attached to a flange located on the proximal end of the injector body. The gate engages a receptor slot in the plunger and prevents movement of the plunger until released. | 09-11-2008 |
| 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. Locking the ring causes the plunger to be advanced by turning a thumbscrew or knob. Unlocking the ring allows the plunger to be advanced by pushing on the thumbscrew or knob in a manner similar to a syringe. | 04-30-2009 |
| 20100094414 | System and method to reduce surface contact between optic and haptic areas - Embodiments of the present invention provide an intraocular lens with an optic zone having a first surface topology and a haptic zone having a second surface topology. The surface roughness of the haptic zone may be greater than the surface roughness of the optic zone. The surface topology of the optic zone may have a first surface geometry and the surface topology of the haptic zone may have a second surface geometry. The first and second surface geometries may retain lubrication fluid in a space formed therein. The haptics formed by the manufacturing process may have a reduced ability to adhere to the optic zone, such as when the lens is folded or advanced through a cannula. | 04-15-2010 |
| 20100121340 | INTRAOCULAR LENS DELIVERY DEVICE WITH A MULTI-PART PLUNGER TIP - The present invention is directed to the provision of an intraocular lens delivery device having a plunger with a multi-part plunger tip. The plunger tip includes a first part and a second part wherein the first part releases from the second part during travel of the plunger through the body of a delivery cartridge. | 05-13-2010 |
| 20100125279 | INTRAOCULAR LENS DELIVERY DEVICE HAVING A CARTRIDGE WITH AN INTERNAL COATING - An intraocular lens (IOL) delivery device is disclosed. The device includes an intraocular lens cartridge having an internal coating wherein the coating includes a polymeric material that is compatible with a polymeric material of a material that forms the cartridge. Preferably, the polymeric material of the coating, the cartridge or both is a polyurethane material. | 05-20-2010 |
| 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. More particularly, the present invention relates to an intraocular lens delivery device that includes a disposable plunger tip segment that can be attached and removed from a reusable plunger base segment. | 12-02-2010 |
