摘要
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.
