Glaucoma drainage device with pump
First Claim
1. A glaucoma drainage device comprising:
- a tube with a first end configured to be located in an anterior chamber of an eye and a second end configured to be located in a drainage location;
a pump in communication with the tube, the pump comprising a driver and a flexible membrane enclosing a chamber;
a first check valve located upstream of the pump;
a second check valve located downstream of the pump;
a first pressure sensor located in fluid communication with the anterior chamber of the eye;
a second pressure sensor located remotely from the first pressure sensor; and
a third pressure sensor located in the drainage location;
wherein a volume of the chamber is changed to pump fluid from the anterior chamber to the drainage location; and
further wherein the tube, the pump, the first check valve, the second check valve, the first pressure sensor, the second pressure sensor, and the third pressure sensor are all located on a single implant.

Abstract
A glaucoma drainage device has a main drainage tube with a first end an anterior chamber of an eye and a second end in a drainage location. A bypass drainage tube is fluidly coupled to and in parallel with the main drainage tube. A pump is in communication with the bypass drainage tube. The pump comprises a first driver and a first flexible membrane enclosing a first chamber. A first check valve is located upstream from the pump, and a second check valve is located downstream from the pump. An active valve is located upstream from the first check valve. The active valve comprises a second driver and a second flexible membrane enclosing a second chamber. A third check valve is located between the active valve and the second end of the main drainage tube. A volume of the first chamber is changed to pump fluid from the anterior chamber.
