Systems, methods, and apparatus for treatment of glaucoma

A glaucoma drainage device, the device comprising:

• a lumen-less elongated body extending axially from a distal end to a proximal end, the body having an I-beam cross-section with opposed upper and lower flat outer surfaces and opposed sides with open grooves extending from the proximal end towards the distal end of the body, wherein the opposed sides with open grooves are disposed between the opposed upper and lower flat outer surfaces of the body, and wherein the open grooves extend along the body between the proximal end and the distal end of the body;
• wherein the body is configured to lodge in the suprachoroidal space of an eye and the open grooves of the body permit aqueous humor from the anterior chamber of the eye to flow along the open grooves to the suprachoroidal space of the eye;
• and
• wherein the body has a plurality of barbs disposed between the proximal end and the distal end of the body on both the upper and lower flat outer surfaces, wherein the plurality of barbs are configured to retain and fixate the body in the suprachoroidal space of the eye, wherein the plurality of barbs includes a first set of barbs that are disposed between and offset from opposed ends of the upper flat outer surface, wherein the first set of barbs include exposed first surfaces that project from and extend parallel to and above the upper flat outer surface with space between the exposed first surfaces, and wherein the plurality of barbs further includes a second set of barbs that are disposed between and offset from the opposed ends of the lower flat outer surface, wherein the second set of barbs include exposed second surfaces that project from and extend parallel to and below the lower flat outer surface with space between the exposed second surfaces.
