A closed loop infusion formulation delivery system for controlling a biological state in the body of a user includes a sensor for generating a signal representative of measured parameters and a computing element for processing the generated signal. The computing element adjusts control parameters within an algorithm, calculates a delivery rate of an infusion formulation and generates commands based on the calculated delivery rate. A remotely located monitoring station communicates with the computing element via radio or wire to further adjust the control parameters within the algorithm to meet changing needs in the body of the user.
