System for infusion of medicine into the body of a patient
First Claim
1. In a system for infusing medication into the body of a patient having an implantable infusion apparatus containing a dosing unit with a reservoir for medication and a pump for pumping doses of said medication from said reservoir into the patient, a sensor for sensing a physiological parameter of the patient for use in controlling the dosing of medication, dependent on said sensed parameter, and an external programmer/controller, the improvement comprising:
- said sensor and said dosing unit having no galvanic connection therebetween;
first telemetry means implanted with and connected to said sensor, for bi-directional telemetry communication with said programmer/controller for transmitting data, at least comprising said sensed parameter, to, and for receiving data and instructions from, said programmer/controller;
second telemetry means implanted with and connected to said dosing unit, for bi-directional telemetry communication with said programmer/controller for transmitting data to, and receiving data and instructions from, said programmer/controller;
third telemetry means, disposed in said programmer/controller, for bi-directional telemetry communication with each of said first and second telemetry means, and means for selectively establishing said bi-directional communication with said first and second telemetry means individually or simultaneously; and
said first, second and third telemetry means comprising, in combination, means for closed-loop telemetric control of the delivery of medication to said patient by communication between said sensor and said dosing unit via said programmer controller.

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.
