HYDRAULIC DELIVERY OF SURGICAL IMPLANTS

An apparatus 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.

AIOL DELIVERY SYSTEMS AND ASSOCIATED DEVICES AND METHODS

The present technology relates to systems, device, and methods for delivering an AIOL into a patients eye. In some embodiments, a tip assembly for delivering an AIOL into a includes an injector tip configured to receive the AIOL. The injector tip can include a distal portion configured to be inserted at least partially into the patients eye. The tip assembly can also include a plunger assembly positionable at least partially within the injector tip. The plunger assembly can include a plunger tip configured to engage the AIOL and an outer member coupled to the plunger tip and positioned at least partially around the plunger tip. When the plunger assembly is actuated, the plunger tip can be configured to move distally relative to the outer member to displace the AIOL out of the injector tip and into the patients eye.

HYBRID POWER DELIVERY FOR SURGICAL IMPLANTS

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.

HAPTIC MANAGEMENT FOR DELIVERY OF INTRAOCULAR IMPLANTS

An apparatus for eye surgery may comprise a nozzle having a delivery lumen, an implant bay coupled to the nozzle, and an implant disposed in the implant bay.
