Ocular implant applier and methods of use
First Claim
1. A method of using a delivery system for implantation of a device into an eye in the absence of a lens or other imaging system, 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.

Abstract
Described herein is a delivery device and methods for delivering an ocular implant into an eye. The delivery device includes 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 and includes 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. Also disclosed is a device and method for loading an implant onto the delivery device.
