Methods for intraocular shunt placement
First Claim
1. A method of delivering an intraocular shunt into an eye having an anterior chamber, a sclera, and a Tenon'"'"'s capsule, the method comprising the steps of:
- advancing a hollow shaft through the anterior chamber, the hollow shaft (a) having a beveled tip at a distal end of the hollow shaft and (b) holding the intraocular shunt with a proximal end of the shunt within the hollow shaft and a distal end of the shunt positioned closer to the distal end of the hollow shaft than is the proximal end of the shunt;
penetrating the sclera with the hollow shaft;
orienting a beveled surface of the beveled tip such that the beveled surface faces toward the Tenon'"'"'s capsule when the beveled tip passes out of the sclera;
after the beveled tip passes out of the sclera, advancing at least a portion of the shunt from the hollow shaft; and
positioning the proximal end of the shunt in the anterior chamber.

Abstract
Intraocular pressure can be reduced by insertion of an intraocular shunt in the eye such that it forms a drainage pathway between the anterior chamber and a region of lower pressure. A hollow shaft can be advanced through the anterior chamber with the hollow shaft (a) having a beveled tip at a distal end of the hollow shaft and (b) holding an intraocular shunt with a proximal end of the shunt within the hollow shaft. The sclera can be penetrated with the hollow shaft. A beveled surface of the beveled tip can be oriented such that the beveled surface faces toward the Tenon'"'"'s capsule when the beveled tip passes out of the sclera. After the beveled tip passes out of the sclera, at least a portion of the shunt can be advanced from the hollow shaft.

15. A method of delivering an intraocular shunt into an eye having an anterior chamber, a sclera, and a Tenon'"'"'s capsule, the method comprising the steps of:
-
inserting into the anterior chamber a hollow shaft, the hollow shaft (a) having a beveled tip at a distal end of the hollow shaft and (b) holding the intraocular shunt with a proximal end of the shunt within the hollow shaft and a distal end of the shunt positioned closer to the distal end of the hollow shaft than is the proximal end of the shunt; advancing the hollow shaft into the sclera; orienting a beveled surface of the beveled tip such that the beveled surface faces away from the sclera when the beveled tip passes out of the sclera; after the beveled tip passes out of the sclera, advancing at least a portion of the shunt from the hollow shaft; with the proximal end of the shunt in the anterior chamber, retracting the hollow shaft from the shunt. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
