Abstract: Multiple embodiments of an implantable infusion device for delivering precisely regulated dosages of drugs are disclosed, each device including reservoir means for containing the drug, catheter means for delivering the drug to the body and an actuating means which is responsive to a signal applied externally of the body for initiating delivery of a precisely regulated dosage. In one embodiment, the device is implanted subcutaneously to permit actuation by a solenoid driven element responsive to coded telemetry signal applied through the skin. In additional embodiments, the reservoir is pressurized for example, by means of vapor pressure or a mechanical spring, the drug under pressure in the reservoir being released in response to an externally applied signal.

Abstract: MEDICAL INFUSION SYSTEM AND METHOD OF OPERATION A medical infusion system is described emploting a pump and cassette combination for conducting fluid or semi-solids from an upstream portion to a downstream portion of the system. The cassette includes a rigid enclosure defining a pumping cavity and has a window with a diaphragm spanning the window. The diaphragm is engaged by an actuator on the pump for varying the volume of the pumping cavity, Restrictors at the upstream and downstrem portions close off and open, respectively, the flow into and out of the pumping cavity in a sequence related to the actuator movement such that the pumping cavity alternately is filled and substantially emptied. To minimize the detrimental effects of air in the pumping cavity: 1) the actuator is operated to substantially increase the volume of the pumping cavity prior to opening of the upstream portion; and 2) the actuator is operated to reduce the volume of the pumping cavity to a residual volume of less than about 0.07 ml subsequent to closing of the upstream portion and opening of the downstream portion.

Abstract: MEDICAL INFUSION SYSTEM A medical infusion system is described employing a pump and cassette combination for conducting fluid or semisolids from an upstream portion to a downstream portion of the system. The cassette includes a rigid enclosure defining a pumping chamber and has a window with a diaphragm spanning the window. The diaphragm is engaged by means on the pump for varying the volume of the pumping chamber. The configuration of the cassette is such that the outlet for the pumping chamber is located at the top of the pumping cavity and the internal configuration of the cavity causes gas bubbles to migrate to the outlet opening. A passage communicates between the outlet opening and a location proximate to the lower portion of the cassette.

Abstract: A pump is described in which a flexible enclosure defines a pump chamber and in which the contents of the pump chamber are expelled by movement of a pair of opposed pusher elements engaged with the enclosure. The pusher elements are displaced by at least one pair of beam springs, each of which is pivotally supported at one end and is engaged with one of the pusher elements at the other end. The ends of the beam springs opposite the pusher elements are pivoted by actuation of symmetrical solenoid armatures, causing each of the springs to be stressed. Relief of the spring stress forces the pusher elements toward each other. De-energization of the solenoid armatures permits the beam springs to pivot back to the original position upon filling of the pump chamber.
