1. An array for dosing a hormone suitable for regulating blood glucose of a patient, comprising:

  • a first sensor for measuring tissue glucose level;

    a controller having as an input the measured tissue glucose level from the first sensor, the controller having a control algorithm to determine an amount of hormone to be dosed based upon the measured tissue glucose level;

    a hormone dosing unit connected to the controller and automatically administering a hormone dose based upon a signal received from the controller;

    a second sensor for measuring an influencing patient variable;

    a pilot control device connected to the second sensor, the pilot control device connected to and forming a circuit with the controller, the pilot control device having a corrective action on the controller based on the influencing patient variable that is measured by the second sensor, whereby the pilot control device reduces dead time of the controller in responding to changes in the patient'"'"'s blood glucose level.
