First Claim
Patent Images
1. An apparatus for transporting aqueous humor from an anterior chamber of an eye, the apparatus comprising:
- an inlet configured to receive aqueous humor from the anterior chamber;
an outlet configured to output aqueous humor to an existing physiologic outflow pathway outside the anterior chamber, said outlet shaped and sized to reside substantially in the existing physiologic outflow pathway; and
a pump configured to pump aqueous humor from the inlet to the outlet, the pump comprising a pair of substantially one-way valves that are spaced to provide a fluid chamber therebetween, the pump being sized and configured to be disposed generally within the anterior chamber or the existing physiologic outflow pathway.

Abstract
A trabecular pump is implantable in the eye to reduce intraocular pressure. The pump drains aqueous humor from the anterior chamber into outflow pathways, such as Schlemm'"'"'s canal. A feedback system includes an intraocular pump and a pressure sensor in communication with the pump, for regulating intraocular pressure.
