  • HYBRID POWER DELIVERY FOR SURGICAL IMPLANTS
    Publication number: 20220192819
    Abstract: A hybrid power system for delivering an implant to an eye using hydraulic fluid flow or pressure. An implant may be stored, advanced, and delivered to an eye using hydraulic fluid stored in a sterile container through a hollow advancement plunger. The plunger may rigidly advance the implant to a sealed position in a first phase, and then the implant may be advanced into the eye via hydraulic pressure or fluid flow in a second phase. The power system may provide a first cell having a first power density and a second cell having a second power density, wherein the second power density is greater than the first power density. A controller may use the first cell during the first delivery phase and the second cell during the second delivery phase.

  • LENS DELIVERY SYSTEM
    Publication number: 20150359624
    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.
