Abstract
A fluid metering device useful in implantable drug delivery systems is coupled between a pressurized fluid source and an outlet conduit to provide discrete flow pulses at a predetermined rate. The metering device consists of a first movable member constrained within a housing and a second movable member retained in a cavity by the first. Alternate positioning of the first member simultaneously fills and empties the cavity in which the second resides, discharging fluid through the conduit. The first movable member can be a planar slider, an axially translatable cylinder or a rotatable cylinder. The second movable member may be a flat shuttle, a sliding bar or a diaphragm.
