Closed loop medicament pump
First Claim
1. A closed loop medicament pump system for a patient for sampling and determining the concentration of a substance of interest through the patient'"'"'s skin and for determining and delivering a responsive dose of an appropriate medicament to the patient comprising:
- an iontopheretic sensor module for sampling and detecting a concentration of a substance of interest through skin, wherein the sensor module comprises a sampling system and a concentration determining system;
a control system, responsive to the iontopheretic sensor module, for determining a response to the sampled and determined concentration of a substance of interest;
a sensor telemetry system for transmitting information regarding the response determined by the control system through the patient'"'"'s body;
a pump telemetry system for receiving information regarding the response determined by the control system through the patient'"'"'s body and for communicating the information to an implantable drug pump; and
an implantable drug pump, acting in response to the information communicated to the implantable drug pump from the pump telemetry system, to deliver a responsive dose of an appropriate medicament to the patient.

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 patient'"'"'s 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. In the preferred embodiment, the substance of interest sensor is an external sensor applied to the user'"'"'s skin.;: In an alternate embodiment, the sensor may be implanted. 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.
