INTRAOCULAR SHUNT DEPLOYMENT DEVICE

摘要

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.

主权项

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.
