  • a reservoir to transiently store a fluid infusate for transmission to a delivery site;

    a flow restrictor disposed in a fluid path between said reservoir and said delivery site;

    a pressure sensing device providing pressure information to determine a pressure differential across said flow restrictor; and

    a valve disposed in said fluid path between said reservoir and said delivery site, said valve operable to control infusate output from said reservoir to said delivery site as a function of said pressure differential across said flow restrictor;

    wherein said reservoir, said flow restrictor, said pressure sensing device, and said valve are provided in a configuration adapted for implantation in a living body.
