Abstract: Devices, systems and methods are provided for treating post-operative symptoms following major surgery and/or for treating patients in critical or intensive care. A method includes positioning a contact surface of a device in contact with an outer skin surface of patient and applying an electrical impulse transcutaneously from the device through the outer skin surface of the patient to a vagus nerve in the patient for about 60 seconds to about 5 minutes. The electrical impulse is sufficient to modify the vagus nerve such that the symptoms are reduced. A stimulation protocol is provided that includes two or more doses administered per day for a period of time sufficient to relieve the symptoms. The doses may be administered before and after the patient's surgery, or while the patient is being treating in intensive care.

Abstract: Methods for treating medical disorders, such as migraine or other primary headaches, or fibromyalgia, by electrical stimulation of a nerve. The method comprises applying a first stimulus to a patient having a medical condition and measuring a first baseline physiological response from the patient. An electrical impulse is applied to a nerve within the patient and second stimulus is applied to the patient. A second physiological response evoked by the second stimulus is measured and compared to the first baseline physiological response. The methods may be used to optimize the placement of a stimulator, to test whether a patient is a suitable candidate for treatment using nerve stimulation, and/or to select the stimulation parameters that optimize acute or chronic treatment.
