Ocular drainage device
First Claim
1. A ocular device comprisinga shunt defining a lumen providing fluid communication between an interior chamber of an eye and an exterior of the eye;
- a stylet received within the lumen of the shunt for implanting the shunt in the eye;
a conduit including a lumen through which the shunt and stylet are disposed while implanting the shunt and the conduit in the eye, the conduit having a collapsible portion for collapsing around the shunt at a collapsing location proximal a distal end of the shunt to reduce or prevent flow through the shunt, the conduit extending along the length of the shunt from a position proximal the collapsing location to a position distal the collapsing location; and
a reservoir operatively coupled to the conduit;
wherein removing the stylet after implanting initiates fluid drainage from the interior chamber of the eye through the shunt into the reservoir.

Abstract
An ocular fluid-draining device to remove fluid from the eye, for example, in a patient after glaucoma surgery. The device includes a shunt at least partially enclosed in a conduit, a portion of the conduit being collapsible or inwardly deformable to control, reduce, or prevent fluid flow. The distal end of the shunt and the conduit is positioned in the eye using a stylet. A reservoir is attached onto the proximal end of the shunt and the conduit. Applying pressure to the conduit cinches it to reduce or close the shunt; releasing this pressure opens the shunt to control the fluid flow from the anterior chamber to the reservoir. One or more components of the fluid draining device may contain medicaments and/or may be coated with amniotic membrane to provide additional desirable properties or effects.

12. An ocular device comprising
a radially expandable shunt defining a lumen providing fluid communication between an interior chamber of an eye and an exterior of the eye; -
a conduit having an elongated, tubular shape with at least a portion of the conduit being collapsible, the conduit including a lumen through which the shunt passes; and a reservoir operatively coupled at a proximal location to the conduit; wherein fluid from the interior chamber of the eye flows through the shunt into the reservoir. - View Dependent Claims (13, 14, 15)

16. A method for fluid drainage from an eye, the method comprising
positioning a device in an eye, the device comprising a shunt defining a lumen, a conduit including a lumen through which the shunt passes, at least a portion of the conduit being partially collapsible and operatively coupled to the shunt for collapsing around the shunt at a location between proximal and distal ends of the conduit to reduce or prevent flow through the shunt, a stylet received within the lumen of the shunt and the conduit, the stylet penetrating the eye to position the device; -
pressurizing the conduit; removing the stylet from the device; and connecting a reservoir to the collapsible conduit for receiving fluid from the eye. - View Dependent Claims (17, 18, 19, 20)
