Adjustable implantable throttle for control of flow rate in implanted drains for drainage of cerebrospinal fluid, wherein at least one effective length of at least one channel is adjustable, wherein the effective length is the length over which the cerebrospinal fluid actually flows. Throttle has at least two states, through and adjustment, wherein in the through state the adjustment disc does not contact the channel boundaries, and in the adjustment state the adjustment disc rests against the channel boundaries.
