1. An implantable apparatus for reducing intraocular pressure within an eye, the apparatus comprising:
a continuous plate structure sized and configured to enable aqueous humor to flow from a first end to a second end, the continuous plate structure comprising:
a main body portion having a proximal end opposite a distal end, the main body portion having a maximum length as measured from a distance between the proximal end and the distal end of the main body portion;
an extension portion having a proximal end opposite a distal end, the extension portion having a maximum length as measured from a distance between the proximal end and the distal end of the extension portion, wherein a longitudinal axis intersects the proximal and distal ends of both the main body portion and the extension portion and the proximal end of the extension portion extends from the distal end of the main body portion;
an uppermost surface opposite a lowermost surface, the uppermost surface including a plurality of open cells; and
a fluid pathway including a plurality of open channels formed into the lowermost surface, the plurality of open channels configured in an intersecting grid pattern extending from the first end to the second end,
wherein the main body portion has a maximum width measured in a direction normal to the longitudinal axis, and the extension portion has a maximum width measured in a direction normal to the longitudinal axis, wherein the maximum width of the main body portion is greater than the maximum width of the extension portion,
wherein the first end of the continuous plate structure is sized and configured to be inserted into an anterior chamber of the eye and the second end of the continuous plate structure is sized and configured to be inserted into at least one of an uveoscleral outflow pathway, Schlemm's canal, a collector channel, a supraciliary space, a trabecular meshwork, a subconjunctival space, or a suprachoroidal space of the eye, and
wherein the continuous plate structure is configured to enable aqueous humor to flow along the fluid pathway, from the first end to the second end, thereby reducing intraocular pressure within the eye.
