1. A system for deploying an intraocular shunt, the system comprising:
- a deployment device and an intraocular shunt carried by the deployment device, the device comprising;
a housing; and
a deployment mechanism at least partially disposed within the housing and comprising a plunger component, a plunger coupled to a distal segment of the plunger component, a plunger arm, a shaft component, a hollow shaft coupled to the shaft component, a shaft arm, and a longitudinal axis, the plunger component comprising a proximal segment and a plunger pin protruding radially from the proximal segment, the plunger arm comprising a plunger hub slot configured to receive a coupling portion of the plunger component for coupling the plunger component to the plunger arm, the shaft component comprising a proximal segment and a shaft pin protruding radially from the shaft component proximal segment, the shaft arm comprising a shaft hub slot configured to receive a coupling portion of the shaft component for coupling the shaft component to the shaft arm;
wherein the shaft is coupled to the deployment mechanism such that the plunger is slidable along the axis within the shaft, wherein the shaft is configured to hold the shunt, andwherein the deployment mechanism is configured (i) to advance the shunt along the axis within the shaft by pushing the shunt with the plunger, without moving the shaft, to a partially exposed position in which a proximal portion of the shunt is disposed within the shaft and a distal portion of the shunt is disposed beyond a distal end of the shaft, and then, (ii) while a longitudinal position of the shunt is substantially maintained along the axis, relative to the housing, by the plunger, to retract the shaft such that the distal end of the shaft is retracted proximally of the shunt proximal portion.

22. A method for deploying a shunt into an eye, the method comprising:
-
providing a system for deploying an intraocular shunt, the system comprising; a deployment device comprising;
a housing;
a deployment mechanism at least partially disposed within the housing and comprising a plunger and a longitudinal axis; and
a hollow shaft coupled to the deployment mechanism such that the plunger is slidably disposed within the shaft along the axis, wherein the shaft is configured to hold an intraocular shunt;inserting the system into an eye; advancing the plunger along the axis to move the shunt to a partially exposed position in which a proximal portion of the shunt is disposed within the shaft and a distal portion of the shunt is disposed beyond a distal end of the shaft; and after advancing the shunt to the exposed position, and while substantially maintaining a longitudinal position of both the plunger and the shunt along the axis, relative to the housing, retracting the distal end of the shaft proximally of the shunt proximal portion to release the shunt from the shaft of the deployment device. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
