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.
