Abstract
A drug delivery system for implantation into a living body having a pressure actuated infusion pump and an adjustable flow regulator. The regulator comprises a body having a regulator cavity divided by a diaphragm into two chambers. One chamber serves as a pressure sensor and the other as a conduit through which fluid flows. The outlet from the conduit chamber can be sealed by diaphragm movement as a function of pressure increase or the flow restricted. The outlet itself is mounted on an adjustable fitting that is movable relative to the diaphragm. The distance between the outlet and the diaphragm may be set as a calibration of the regulator.
