US Patent 9693901 Shunt placement through the sclera

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 sclera can be penetrated with the beveled distal tip until all of the bevel is positioned distal to a distal 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 The hollow shaft can be withdrawn from the eye, leaving the shunt extending from the anterior chamber completely through the sclera to the drainage space.
