1. A device for implanting into an eye, comprising:
a curved fixation stent having a first end and a second end separated by the length of the fixation stent, the curved fixation stent including one or more through-holes across a width of the curved fixation stent from a first side to a second side of the curved fixation stent, wherein at least a portion of the curved fixation stent has a cylindrical cross-section; and
a first drainage tube with a first end and a second end, constructed and arranged to be insertable into one of the one or more through-holes in the curved fixation stent,
wherein a first fluid flow path for fluid to enter or exit the device exists between the first and second ends of the curved fixation stent, and inserting the first drainage tube into the curved fixation stent creates a second fluid flow path transverse to the first fluid flow path,
wherein the first drainage tube comprises a bulge in between the first end and the second end of the first drainage tube, and
wherein the bulge snap-fits with a through-hole of the one or more through-holes of the curved fixation stent.
