Embodiment Construction

[0088] figure 1 It is a cross-sectional perspective view of a part of the eye showing the anterior chamber and the posterior chamber of the eye. The shunt 105 is placed in the eye so that the proximal end 110 is in the anterior chamber 115 and the distal end 120 is in the suprachoroidal space (sometimes referred to as the extrachoroidal space). The shunt 105 is shown as an elongated element with one or more internal lumens in figure 1 , through this inner lumen, aqueous humor can flow from the anterior chamber 115 into the suprachoroidal space. Details of embodiments of shunt tubes 105 having various structural layouts are described below.

Abstract

Methods and devices are adapted for implanting into the eye. An incision is formed in the cornea of the eye and a shunt is inserted through the incision into the anterior chamber of the eye. The shunt includes a fluid passageway. The shunt is passed along a pathway from the anterior chamber through the scleral spur of the eye into the suprachoroidal space and positioned in a first position such that a first portion of the fluid passageway communicates with the anterior chamber and a second portion of the fluid passageway communicates with the suprachoroidal space to provide a fluid passagewaybetween the suprachoroidal space and the anterior chamber.
