Intraocular shunt deployment device
First Claim
Patent Images
1. A device for deploying an intraocular shunt, the device comprising:
- a housing;
a hollow shaft, coupled to the housing, configured to hold an intraocular shunt;
a plunger, slidably disposed within the shaft;
a rotating component, coupled to the housing, having first and second slots;
a pusher component, coupled to the plunger, having a first member that resides within the first slot to couple the pusher component with the rotating component such that rotation of the rotating component causes distal axial movement of the first member, thereby urging the plunger in a distal axial direction to advance the shunt partially from within the shaft; and
a retraction component, coupled to the shaft, having a second member that resides within the second slot to couple the retraction component with the rotating component such that further rotation of the rotating component causes proximal axial movement of the second member, thereby urging the shaft in a proximal axial direction relative to the shunt.

Abstract
An intraocular shunt deployment device can release an intraocular shunt into an eye using a deployment mechanism that coordinates action between a pusher component, a shaft component, and a housing of the device. The deployment mechanism causes axial movement of the components in response to a rotational input force.

9. A device for deploying an intraocular shunt, the device comprising:
-
a housing; a hollow shaft, coupled to the housing, configured to hold an intraocular shunt; a plunger slidably disposed within the shaft; a deployment mechanism at least partially disposed within the housing, the deployment mechanism comprising a rotating component, a pusher component coupled to the plunger, and a retraction component coupled to the shaft, the rotating component being operably coupled to the pusher and retraction components by first and second slots and first and second protruding members slidably disposed within the respective first and second slots; wherein rotation of the rotating component causes (i) axial movement of the pusher component to urge the plunger distally relative to the shaft and the housing and (ii) axial movement of the retraction component to urge the shaft proximally relative to the plunger and the housing. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

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 a rotating component, a pusher component, and a retraction component, the rotating component being operably coupled to the pusher and retraction components by first and second slots and first and second protruding members slidably disposed within the respective first and second slots; wherein rotation of the rotating component causes (i) distal axial movement of the pusher component relative to the housing to push a stent within the device, and (ii) proximal axial movement of the retraction component to expose the stent from the device. - View Dependent Claims (18, 19, 20)
