ABSTRACT:
A system for infusing medicine into the body of a patient includes an implantable infusion apparatus containing a dosing unit with a reservoir for the medicine and a medicine delivery pump for pumping doses of the medicine from the reservoir into the patient. The infusion apparatus also includes a sensor for sensing a parameter of the patient for controlling the dosing of medicine according to the sensed parameter. The dosing unit and the sensor are galvanically separable and are each provided with separate telemetry communication units for communication with an external programmer/controller. The external programmer/controller includes telemetry communication units for selectable communication with the dosing unit or the sensor or both simultaneously. The telemetry communication units of the external programmer/controller, the dosing unit and the sensor are constructed for bi-directional communication between the external controller and each one of the dosing unit and the sensor.
