US Patent 9980854 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 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 The hollow shaft can be withdrawn from the eye, leaving the shunt extending from the anterior chamber completely through the sclera to the drainage space.
