Hydraulic Delivery of Surgical Implants

An apparatus for ejecting an implant for eye surgery, the apparatus comprising:

• a nozzle having a delivery lumen;
• an implant bay coupled to the nozzle;
• and
• an actuator coupled to the implant bay, the actuator comprising a housing and a plunger disposed within the housing;
• wherein the plunger comprises a shaft having a first end and a second end, an implant interface is configured to advance the implant from the implant bay to the delivery lumen, a bore between the first end and the second end, and a fluid coupling proximate to the second end of the shaft configured to fluidly couple a working fluid to the delivery lumen through the bore to advance the implant through the delivery lumen.

A method of ejecting an implant from a delivery system, the method comprising:

• providing the implant in an implant bay;
• coupling a hydraulic driver to a plunger;
• driving the plunger with the hydraulic driver to advance the implant from the implant bay to a delivery lumen;
• pressing a working fluid from the hydraulic driver to move the working fluid through a bore in the plunger to the delivery lumen;
• and
• advancing the implant through the delivery lumen with the working fluid.

An apparatus for eye surgery, the apparatus comprising:

• a nozzle having a delivery lumen;
• an implant bay coupled to the nozzle;
• a working fluid disposed in the implant bay;
• an implant disposed in the working fluid;
• and
• an actuator coupled to the implant bay, the actuator comprising a housing and a plunger having a seal disposed within the implant bay;
• wherein the seal is configured to advance the working fluid and the implant from the implant bay through the delivery lumen.
