CLOSED LOOP MEDICAMENT PUMP
First Claim
1. A closed loop medicament pump for a patient for sampling and determining the concentration of a substance of interest from among the group of biological chemicals, enzymes, and hormones, and for determining and delivering a responsive dose of an appropriate medicament to the patient comprising:
- a sensor for sampling and determining the concentration of a substance of interest in the patient;
a control system for determining an appropriate response to the determined concentration of the substance of interest;
an implantable drug pump for dispensing an appropriate amount of a medicament to the patient;
a first communications system capable of communicating information, regarding the sensed concentration of a substance of interest in the patient, from the sensor to the control system; and
,a second communications system capable of communicating information, regarding the determined response to the determined concentration of the substance of interest, from the control system to the implantable drug pump.

Abstract
A device to determine the level of a substance of interest in a patient'"'"'s body and provide a therapeutic amount of medicament is disclosed. The level of a substance of interest in the patient'"'"'s body is determined by iontopheretically sampling the patients'"'"' blood and then analyzing the resulting sample to determine the level of the substance of interest. The information about the level of a substance of interest is transmitted to an implanted drug pump in the patient'"'"'s body. The preferred method of transmitting information about the level of a substance of interest determined by the sensor is transmitted to an implanted drug pump in the patient'"'"'s body is via a so called “body bus”. The “body bus” is a telemetry system where the patient'"'"'s own body provides the interconnection between the iontopheretic device and the implanted drug pump.
