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.

Claims

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 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 the needle and plunger grooves; and

a slider component coupled to the housing and slidable therealong, the slider component coupled to the drive component via 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.

2. The inserter of claim 1, wherein the cylindrical member is hollow.

3. The inserter of claim 1, wherein the drive component comprises the plunger groove, the plunger groove being configured to engage with the plunger such that upon rotation of the drive component, the engagement results in movement to the plunger along the axis in response to a rotational movement of the drive component.

4. The inserter of claim 1, wherein the drive component comprises the needle groove, the needle groove being configured to engage with the needle such that upon rotation of the drive component, the engagement results in a movement to the needle along the axis in response to a rotational movement of the drive component.

5. The inserter of claim 1, wherein the housing comprises an interior cavity, wherein the drive component is supported within the cavity.

6. The inserter of claim 5, wherein the housing comprises an elongate slot extending from an outer surface of the housing into the cavity, the slider component being slidable along the slot.

7. The inserter of claim 6, further comprising a lock component configured to engage an outer structure of the housing to restrict movement of the slider component within the housing slot.

8. The inserter of claim 6, further comprising a lock component extending at least partially through the housing slot and configured to engage an outer structure of the drive component to restrict rotational movement of the drive component within the housing.

9. The inserter of claim 5, further comprising a knob component coupled to a proximal end of the housing, the knob component being rotatably coupled to the drive component such that rotation of the knob component results in a rotational movement to the drive component.

10. The inserter of claim 1, wherein the needle is coupled to a rotational adjustment component, the adjustment component being coupled to a needle driver of a needle assembly, the adjustment component being rotatable relative to the needle driver such that rotation of the adjustment component rotation of the adjustment component changes a rotational alignment of the needle relative to the housing, wherein the adjustment component is rotatable to fix the rotational alignment of the needle relative to the housing.

11. An inserter for treating glaucoma, comprising:

a housing;

a needle having a lumen;

a plunger, movable within the lumen;

a drive component disposed at least partially within the housing and comprising a slider groove, a plunger groove, and a needle groove extending along the drive component, the drive component being coupled to the needle via the needle groove and to the plunger via the plunger groove to drive movement to the needle and the plunger along a longitudinal axis of the inserter upon rotation of the drive component, wherein a first end of the slider groove is positioned at a proximal position on the drive component with respect to the needle groove and the plunger groove, and wherein a second end of the slider groove is positioned between a first end of the needle groove and a first end of 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.

12. The inserter of claim 11, wherein the drive component comprises a hollow cylindrical member.

13. The inserter of claim 11, wherein the housing comprises an interior cavity, the drive component being supported within the cavity.

14. The inserter of claim 13, wherein the housing comprises an elongate slot extending from an outer surface of the housing into the cavity, the slider component being slidable along the slot.

15. The inserter of claim 14, further comprising a lock component configured to engage an outer structure of the housing to restrict movement of the slider component within the elongate slot.

16. The inserter of claim 14, further comprising a lock component extending at least partially through the elongate slot and configured to engage an outer structure of the drive component to restrict rotational movement of the drive component within the housing.

17. The inserter of claim 11, wherein the needle is coupled to a rotational adjustment component, the adjustment component being coupled to a needle driver of a needle assembly, the adjustment component being rotatable relative to the needle driver such that rotation of the adjustment component rotation of the adjustment component changes a rotational alignment of the needle relative to the housing, wherein the adjustment component is rotatable to fix the rotational alignment of the needle relative to the housing.

18. The inserter of claim 11, wherein the slider groove extends along a half rotation of the drive component.

19. The inserter of claim 11, wherein the plunger groove extends along a half rotation of the drive component.

20. The inserter of claim 11, wherein the needle groove extends along a half rotation of the drive component.
