An implantable valve assembly including a drainage catheter having a centrallumen transitioning into a plurality of distinct branch lumen made of a shapememorymaterial. A bioabsorbable dip coating secures the distal end of the pluraldistinct branchlumen together in physical contact with one another. Each branch lumen has anouterperimeter comprising at least one of a first outer surface section and asecond outersurface section. In a secured state with the plural distinct branch lumen heldtogether bythe dip coating fluid is prohibited from passing through the holes defined inthe first outersurface section. Bioabsorbable blocking members disposed about the outerperimeter ofthe assembled branch lumen mask holes defined in the second outer surfacesectionprohibiting fluid from entering therein. In a time staggered fashion, thebioabsorbableelements absorb exposing new holes through which the fluid drains.
