Patent ID: 8924023

Claim:
A method for gauging the performance of an infusion system implanted in a patient, the method comprising: receiving input into an external device regarding the identity of a therapeutic agent contained in an implanted infusion device of the infusion system, the external device being capable of communicating with an implanted infusion device of the infusion system; displaying on the external device a predetermined set of symptoms associated with the therapeutic agent; receiving input into the external device regarding with which of the predetermined set of symptoms the patient presents; determining whether the therapeutic agent is being delivered, or has been delivered, at an appropriate dose to the patient based on the input identity of the therapeutic agent and the patient's presented symptoms; displaying on the external device whether the patient is receiving the appropriate dose of the therapeutic agent; interrogating the infusion device to identify at least one potential source of inappropriate dosing if it is determined that the therapeutic agent is not being delivered, or has not been delivered, at an appropriate dose; displaying on the external device the at least one potential source of the inappropriate dosing based on the interrogation of the implanted infusion device; and determining probabilities that the at least one potential source contributes to the inappropriate dosing by comparing data regarding the at least one potential source to a lookup table and displaying the probabilities for the displayed at least one potential source.
