1. A device for deploying an intraocular shunt, the device comprising:
- a housing comprising a proximal portion and a distal portion, the distal portion comprising a sleeve;
a deployment mechanism at least partially disposed within the housing; and
a hollow shaft coupled inside the housing to the deployment mechanism, wherein the shaft is positioned at least partially within the sleeve and configured to hold an intraocular shunt at least partially within the shaft;
wherein the distal portion is movable (i) relative to the proximal portion, the deployment mechanism, and the hollow shaft and (ii) between a distal position and a proximal position, the distal portion being biased toward the distal position;
wherein the deployment mechanism comprises a pusher component and a retraction component;
wherein the deployment mechanism comprises a rotatable portion, the rotatable portion being configured to sequentially engage the pusher component and then the retraction component as the rotatable distal portion rotates.

Abstract
The present invention generally relates to devices for deploying intraocular shunts without the use of an optical apparatus that contacts an eye, such as a goniolens. 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 inside the housing to the deployment mechanism, in which the shaft is configured to hold an intraocular shunt, and the device includes an insertion configuration and a deployment configuration and the insertion configuration involves the shaft being fully disposed within the housing.

16. 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 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 and a deployment configuration and, when the device is in the insertion configuration, the shaft is fully disposed within the housing; wherein a distal end of the sleeve comprises a protrusion that provides resistance against advancement of the device when the protrusion contacts scleral tissue on an inside of an anterior chamber. - View Dependent Claims (17, 18, 19, 20, 21)
