International Classification:

A61F 9/007

US Classification:

606108, 128898, 604 8

Abstract:

An insertion tool and method are provided for implanting an ophthalmic shunt having a foot, a head and a body connecting the foot and head. The insertion tool has a first arm having a proximal end and a distal end and a second arm having a proximal end and a distal end. The second arm is movable with respect to the first arm between an open position and a closed position. A means to grip a shunt is disposed on the distal ends of the first and second arms. In use, the insertion tool is employed to selectively grip the shunt for placement in the tissue of the eye and, as desired, to orient the shunt after placement.

Abstract:

A loading station receives a substrate into a load-lock volume pressure isolated from a loading station chamber which is open to a processing chamber. The volume is evacuated and the substrate lowered into the loading chamber. A transport arm moves the substrate from the loading station to a substrate carrier of a cooling fixture within the processing chamber. The carrier is connected to a clamp which together move vertically downward to lower the wafer onto a substrate seat of the fixture. During substrate processing the fixture is tiltable and rotatable and provides substrate cooling by solid-to-solid conduction, forced convection and free convection. Solid-to-solid conduction is provided by the clamp. The substrate is pressed to the fixture by the cooling clamp having a circulating cooling fluid. Forced convection is provided by a gas flowing into the microscopic areas between the substrate and the fixture at a pressure high enough to cause bowing or lifting of the substrate and thus to create a gas region between the substrate and the fixture.
