1. A system for treating an ocular disorder, comprising:

  • a shunt formed from polyimide, the shunt comprising;

    a lumen extending through the shunt;

    one or more outlet openings located on a body of the shunt and communicating with the lumen;

    a flange along a proximal portion of the shunt; and

    radial extensions located on an exterior surface of the shunt to resist extrusion of the shunt from the supraciliary or suprachoroidal space, the radial extensions formed by at least three radial grooves;

    wherein the shunt has a length between 2 mm and 7 mm, andwherein the shunt is generally rigid such that the shunt generally maintains its preformed shape when implanted;

    a delivery instrument to deliver the shunt, the delivery instrument comprising a body with an open distal end and a plurality of members being at least partially disposed within the body and being longitudinally moveable relative to each other to aid in delivery of the shunt, the delivery instrument comprising a spring to actuate at least one of the plurality of members, the plurality of members comprising;

    a flexible wire having a pre-formed curved shape, the wire being movable within the lumen of the shunt; and

    a pusher being at least partially within the body of the delivery instrument and adapted to inhibit proximal movement of the shunt during delivery;

    wherein the plurality of members are configured to advance the shunt to a location near the scleral spur and through ciliary attachment tissue.
