FLUID DRAINAGE DEVICES, SYSTEMS, AND METHODS

Glaucoma shunts for draining fluid from an eye to surrounding tissue and being implantable within eye tissue, the shunts include a shunt body formed from microporous materials arranged to form a reservoir within the shunt body, and a conduit having a proximal end in fluid communication with the reservoir and an opposing distal end, the distal end being insertable into the eye to facilitate drainage of fluid into the conduit via the distal end, wherein the conduit and the reservoir together define a flow passage along which drainage of fluid flows through the conduit, to the reservoir, and into surrounding tissue via the microporous material, wherein the flow passage presents a variable flow resistance along the conduit that has a plurality of sequential flow resistances with first and second flow resistances defined therein such that the first flow resistance is different from the second flow resistance.
