Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An intraocular lens (“IOL”) cartridge includes an upper wall and a lower wall, together defining a lumen for receiving an IOL. The proximal end of the cartridge has an open slot cut into and through the entire thickness of the upper wall so to allow the leading haptic of the IOL to extend above the upper wall. The cartridge includes a proximal-end feature to facilitate folding of the leading haptic radially inward relative to the optic as the IOL moves into the lumen.

Abstract: 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.

Abstract: 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.

Abstract: A golf ball component, such as a golf ball cover layer, formed from a self cross-linkable thermoplastic polyurethane, polyurea or polyurethane/polyurea is disclosed. The self cross-linkable thermoplastic polyurethane, polyurea or polyurethane/polyurea is cross-linked during molding without the need for an independent cross-linking agent; such as an isocyanate. The cover layer may be relatively thin (i.e., 0.075 or less, preferably less than 0.040 inches). In addition, the outer cover may be further treated, such as by exposure to an isocyanate solution, to improve certain physical properties of the resulting golf ball.
