A method, apparatus, and system for determining an adverse operational condition associated with a lead assembly in an implantable medical device used for providing a therapeutic electrical signal to a cranial nerve. A first impedance associated with the lead assembly configured to provide the therapeutic electrical signal to a cranial nerve is detected. A determination is made as to whether the first impedance is outside a first predetermined range. A second impedance is detected. The detection of the second impedance is performed within a predetermined period of time from the time of the detection of the first impedance. A determination is made as to whether the second impedance is outside a second predetermined range. If the first impedance is outside the first range and the second impedance is outside the second range, the implantable medical device is prevented from providing the therapeutic electrical signal.

Alternative operation mode for an implantable medical device based upon lead condition

A method, system, graphical user interface, and apparatus are provided for performing a patient management function for treating depression using an implantable medical device. At least one patient parameter relating to an electrical signal provided by the implantable medical device for treating depression is acquired. At least one therapy parameter defining the electrical signal is correlated with at least one patient parameter. An indication relating to the correlation of the therapy parameter and the patient parameter is provided.

Patient management system for treating depression using an implantable medical device

A method, system, graphical user interface, and apparatus are provided for performing a patient management function providing parameter data for delivering a therapeutic signal. A first electrical signal comprising a first therapy parameter is applied to a portion of a patient's body for providing a therapy. At least one patient parameter relating to an effect of applying the first electrical signal is acquired. A second therapy parameter for defining a second electrical signal to provide a therapy is determined in response to the patient parameter. The second therapy parameter is displayed on an external device. An input signal for defining the second electrical signal is received. The input signal includes a signal indicative of the whether the second therapy parameter was accepted or not.
