OCULAR IMPLANT APPLIER AND METHODS OF USE
First Claim
1. A delivery device for delivering an ocular implant into an eye, the delivery device comprising:
- a proximal handle portion;
a distal delivery portion coupled to a distal end of the handle portion and configured to releasably hold an ocular implant, the delivery portion comprising a sheath positioned axially over a guidewire; and
a metering system configured to provide visual guidance regarding depth of advancement of an implant positioned on the guidewire into an anatomic region of the eye.

13. A method of using a delivery system for implantation of a device into an eye, the method comprising:
-
mounting an implant on a delivery device comprising a guidewire having a sheath coupled to the guidewire, wherein the guidewire comprises a first metering system at a distal end of the guidewire and the sheath comprises a second metering system at a distal end of the sheath, the first and second metering systems having corresponding graduated markings; inserting the implant on the delivery device into an anterior chamber through an incision in a cornea; advancing the implant on the delivery device through a transparent zone of the anterior chamber toward an opaque zone of the anterior chamber; seating a distal end of the guidewire at eye tissue where resistance is felt; reading through the transparent zone a first graduated marking of the first metering system, wherein the first graduated marking is aligned with an edge between the transparent zone and the opaque zone; advancing the implant on the guidewire into the eye tissue beyond where resistance is felt; and reading through the transparent zone a second graduated marking on the second metering system, wherein the second graduated marking is aligned with the edge between the transparent zone and the opaque zone. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method of implanting an ocular device into an eye, comprising:
-
loading onto a delivery device a shunt having a proximal end, a distal end and a fluid passageway extending between the proximal end and the distal end; inserting the shunt loaded on the delivery device through an incision in a cornea and into an anterior chamber of the eye; passing the shunt from the anterior chamber past the scleral spur near the ciliary body of the eye into the suprachoroidal space; and positioning the shunt in a first position such that a first portion of the fluid passageway communicates with the anterior chamber and a second portion of the fluid passageway communicates with the suprachoroidal space to provide a fluid passageway between the suprachoroidal space and the anterior chamber. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
