Flow regulators for implantable drug delivery devices ( 100 ) and drug delivery devices produced therewith. Implantable drug delivery devices ( 100 ) employing diffusion, osmosis, electrodiffusion, electroosmosis, or a combination of one or more of these for driving one or more drugs therefrom are provided with cover members ( 126, 128 ) for varying at least one of an effective cross-sectional area and transport characteristics through which fluids diffuse or osmose. The cover members may be remotely actuated from a location outside of an implantation site after implantation of a device. |
