1. A reduced size implantable pump for dispensing an active substance at one or varying flow rates to a patient comprising:
- a pump housing defining an interior and having a top surface and a bottom surface;
a valve disposed within the interior, the valve being capable of moving in a direction extending between the top and bottom surfaces;
a propellant envelope disposed within the interior, the propellant envelope defining an active substance chamber and a propellant chamber; and
a hermetic housing attached to the pump housing, the hermetic housing including a first pressure sensor, a second pressure sensor, and an actuator capable of moving the valve.
