1. A medical system comprising:
- a monitoring device comprising an electronic control circuitry that is configured to monitor a rate of change in a selected state of a subject, wherein said monitoring device further comprises a telemetry system;
a therapeutic substance delivery device comprising an electronic control circuitry that is configured to deliver insulin to the subject; and
a receiver-controller device comprising an electronic circuitry that is configured to receive a signal generated by said monitoring device and is further configured to control the operation of said therapeutic substance delivery device based on the rate of change in the selected state of the subject as monitored by said monitoring device wherein said receiver-controller is configured to reduce or stop administering insulin then the glucose level decreases and to automatically resume delivery of insulin about 1 hour to about 2 hours after insulin delivery is reduced or stopped.
