1. An inserter for treating glaucoma, comprising:
- a housing;
a needle having a lumen;
a plunger, movable within the lumen;
a drive component comprising a cylindrical member being coupled to the plunger via a plunger groove to result in movement to the plunger along a longitudinal axis of the inserter upon rotation of the drive component, the drive component further comprising a slider groove that longitudinally overlaps with the plunger groove; and
a slider component coupled to the housing and slidable along the slider groove such that movement of the slider component along the axis rotates the drive component within the housing and results in movement of the plunger along the axis.

Abstract
An inserter for treating glaucoma can comprise a housing, a needle, a plunger, a slider component, and a drive component. The drive component is disposed within a cavity of the housing and rotatable within the cavity to result in movement along a longitudinal axis of the inserter to the needle and the plunger upon rotation of the drive component. The slider component is coupled to the housing and slidable along an elongate groove of the drive component such that movement of the slider component along the axis rotates the drive component within the housing.

- 12. A drive component for actuating an inserter for treating glaucoma, the drive component comprising a cylindrical body having first and second elongate tracks extending along the body, wherein the first elongate track extends helically from a proximal portion toward a distal portion of the body to longitudinally overlap with the second elongate track by intersecting with a common plane that is oriented substantially perpendicular relative to a longitudinal axis of the body, the second elongate track having (1) a first portion, extending helically about the body, and (2) a second portion, extending circumferentially about the body.

21. An inserter for treating glaucoma, comprising:
-
a housing; a needle having a lumen; a plunger, movable within the lumen; a drive component comprising a cylindrical member being coupled to the needle via a needle groove and to the plunger via a plunger groove to result in movement to the needle and the plunger along a longitudinal axis of the inserter upon rotation of the drive component, the drive component further comprising a slider groove that longitudinally overlaps with at least one of the needle groove or the plunger groove; and a slider component coupled to the housing and slidable along the slider groove such that movement of the slider component along the axis rotates the drive component within the housing and results in movement of the needle and the plunger along the axis. - View Dependent Claims (22, 23, 24, 25)
