Intraocular shunt implantation
First Claim
Patent Images
1. A method of treating glaucoma comprising:
- inserting a shaft of an inserter device into eye tissue, the device supporting an intraocular shunt and comprising a sleeve that extends about at least a portion of the shaft;
advancing the shaft until reaching a first position at which (i) a bevel of the shaft is in a space adjacent to Tenon'"'"'s capsule and (ii) a distal end of the sleeve is spaced apart from the eye tissue;
releasing the shunt from the shaft such that an inflow end of the shunt is positioned in an anterior chamber of the eye and an outflow end of the shunt is positioned in a space in contact with Tenon'"'"'s capsule;
advancing the sleeve distally over the shaft until the sleeve distal end contacts the eye tissue; and
withdrawing the shaft and sleeve from the eye.

Abstract
Implanting an intraocular shunt into an eye can involve creating an opening in the cornea and positioning a shunt in the anterior chamber of the eye such that the shunt terminates between layers of Tenon'"'"'s capsule, thereby facilitating fluid flow out of the anterior chamber into a space between the layers of Tenon'"'"'s capsule.

16. A method of treating glaucoma comprising:
-
advancing a shaft of a device into eye tissue until a bevel of the shaft reaches a target area and a sleeve of the device is spaced apart from the eye tissue, the shaft supporting an intraocular shunt; advancing the shunt from the shaft into the target area; while maintaining the bevel stationary relative to the target area, advancing the sleeve distally over the shaft until a distal end of the sleeve contacts the eye tissue; and upon contacting the sleeve distal end with the eye tissue, proximally withdrawing the shaft from the eye tissue. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
