ABSTRACT An improved version of an osmotically driven minipump that is used to administer drug solutions is disclosed. The basic components of the improved minipump are: an inner flexible bag that holds the drug solution; a plug having a recessed inner end that seals the bag opening; a solution filling/discharge port through the plug; a cup-shaped, thermoformed sleeve that fits partly about the bag and is made from a dispersion of an osmotically effective solute in a water soluble, thermoplastic polymer vehicle; a shape-retaining, semipermeable membrane that encapsulates the bag-sleeve subassembly; and a flow moderator that is received through the filling/discharge port in the plug.
