Shunt placement through the sclera
First Claim
1. A method of placing an intraocular shunt into a human eye comprising an anterior chamber and a sclera, the method comprising:
- advancing a hollow shaft through the anterior chamber, the hollow shaft holding the intraocular shunt and having a distal tip, the distal tip comprising a bevel, the shunt comprising a pharmaceutical or biological agent deliverable to the eye;
penetrating the sclera with the beveled distal tip until all of the bevel is positioned distal to a superficial wall of the sclera;
after all of the bevel has been positioned distal to the superficial wall, advancing the shunt at least partially from the hollow shaft into a drainage space of lower pressure than the anterior chamber; and
withdrawing the hollow shaft from the eye and leaving the shunt extending from the anterior chamber completely through the sclera to the drainage space.

Abstract
An intraocular shunt can be placed into a human eye using a hollow shaft having a distal tip with a bevel. The hollow shaft can be advanced through the anterior chamber while the hollow shaft holds the intraocular shunt. The distal tip can penetrate the sclera until the bevel is positioned distal to a superficial wall of the sclera. The shunt can be advanced at least partially from the hollow shaft into a drainage space of lower pressure than the anterior chamber. The hollow shaft can be withdrawn from the eye, leaving the shunt extending from the anterior chamber completely through the sclera to the drainage space.

11. A method of placing an intraocular shunt into an eye comprising an anterior chamber, a sclera, and a Tenon'"'"'s capsule, the method comprising:
-
inserting a hollow shaft from the anterior chamber through the sclera toward the Tenon'"'"'s capsule, the hollow shaft holding the intraocular shunt and having a beveled distal tip and an unbeveled portion proximal to the beveled distal tip, the shunt comprising a pharmaceutical or biological agent deliverable to the eye; positioning the unbeveled portion distal to a superficial wall of the sclera; and after positioning the unbeveled portion distal to the superficial wall of the sclera, withdrawing the hollow shaft from the eye and leaving (i) a distal end of the shunt in a drainage space superficial to the sclera and (ii) a proximal end of the shunt in the anterior chamber. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
