1. A device for deploying an intraocular shunt, the device comprising:
- a housing;
a sleeve coupled to the housing;
a needle (i) positioned at least partially within the sleeve and (ii) configured to hold an intraocular shunt;
a pusher component axially movable within the needle;
a retraction component configured to retract the needle inside the housing; and
a rotatable deployment portion configured to rotate in a first direction to sequentially move the pusher component and to continue rotation in the first direction to subsequently engage with and move the retraction component.

12. A device for deploying an intraocular shunt, the device comprising:
-
a housing comprising a sleeve, the sleeve comprising a distal contact surface that provides resistance against advancement of the device when the contact surface contacts anterior chamber angle tissue on an inside of an anterior chamber; a deployment mechanism at least partially disposed within the housing; and a needle coupled inside the housing to the deployment mechanism, wherein the needle is configured to hold an intraocular shunt; wherein the device comprises an insertion configuration and a deployment configuration and, when the device is in the insertion configuration, the needle extends distally beyond the sleeve, and when the device is in the deployment configuration, the needle is fully disposed within the sleeve; and wherein the deployment mechanism is configured to rotate in a first direction to sequentially push the shunt within the needle and to continue rotation in the first direction to subsequently engage with and retract the needle relative to the housing. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A device for deploying an intraocular shunt, the device comprising:
-
a housing comprising a sleeve; a deployment mechanism at least partially disposed within the housing; and a needle extending within the sleeve and coupled to the deployment mechanism, the needle being configured to hold an intraocular shunt, the needle being fully disposed within the sleeve when the shunt is released from the needle; wherein the deployment mechanism is configured to rotate in a first direction to sequentially push the shunt within the needle and to continue rotation in the first direction to subsequently engage with and retract the needle relative to the housing. - View Dependent Claims (21, 22, 23)
