1. A device for deploying an intraocular shunt, the device comprising:
- a housing;
a deployment mechanism at least partially disposed within the housing, the deployment mechanism comprising (i) a rotating component having a diagonal first slot and a diagonal second slot, (ii) a pusher component having a first member that sits within the first slot, and (iii) a retraction component having a second member that sits within the second slot; and
a hollow shaft coupled to the deployment mechanism, wherein the shaft is configured to hold an intraocular shunt;
wherein rotation of the rotating component causes distal axial movement of the first member thereby urging the pusher component in a distal axial direction to advance the shunt partially from within the shaft, andwherein further rotation of the rotating component causes proximal axial movement of the second member thereby urging the retraction component in a proximal axial direction to retract the shaft from around the shunt, thereby exposing the shunt.

Abstract
The invention generally relates to devices for deploying an intraocular shunt within an eye. In certain embodiments, devices of the invention include a housing, a deployment mechanism at least partially disposed within the housing, and a hollow shaft coupled to the deployment mechanism, in which the shaft is configured to hold an intraocular shunt, and in which rotation of the deployment mechanism results in deployment of the shunt.

17. A device for deploying an intraocular shunt, the device comprising:
-
a housing; a deployment mechanism at least partially disposed within the housing, the deployment mechanism comprising (i) a rotating component having a diagonal first slot and a diagonal second slot, (ii) a pusher component having a first member that sits within the first slot, and (iii) a retraction component having a second member that sits within the second slot, the rotating component of the deployment mechanism being configured to sequentially engage the pusher component and then the retraction component; and a hollow shaft coupled to the deployment mechanism, wherein the shaft is configured to hold an intraocular shunt; wherein rotation of the rotating component causes distal axial movement of the first member thereby urging the pusher component in a distal axial direction to advance the shunt out of the shaft, and wherein further rotation of the rotating component causes proximal axial movement of the second member thereby urging the retraction component in a proximal axial direction to retract the shaft from around the shunt at least partially into the housing while the pusher component limits axial movement of the shunt, thereby exposing the shunt. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A device for deploying an intraocular shunt, the device comprising:
-
a housing; a deployment mechanism at least partially disposed within the housing, the deployment mechanism comprising (i) a rotating component having a diagonal first slot and a diagonal second slot, (ii) a pusher component having a first member that sits within the first slot, and (iii) a retraction component having a second member that sits within the second slot, the rotating component of the deployment mechanism being configured to sequentially engage the pusher component and then the retraction component; and a hollow shaft coupled inside the housing to the deployment mechanism, wherein the shaft is configured to hold an intraocular shunt; wherein the device comprises an insertion configuration in which rotation of the rotating component causes distal axial movement of the first member thereby urging the pusher component in a distal direction to advance the shunt from within the shaft and a deployment configuration in which further rotation of the rotating component causes proximal axial movement of the second member thereby urging the retraction component in a proximal axial direction to retract the shaft from around the shunt at least partially retracted into the housing relative to the pusher component, thereby exposing the shunt. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
