1. A device comprising:an enclosure hosting a contact surface;
a power source positioned within the enclosure and configured to generate an electric field comprising bursts of pulses having a frequency from about 5 bursts per second to about 100 bursts per second with each of the pulses generated from a signal that is not modulated by another signal;
an electrode coupled to the power source and positioned within the enclosure;
an electrically conductive medium positioned between the electrode and the contact surface, wherein the power source is configured to transmit the electric field from the electrode through the electrically conductive medium and the contact surface transcutaneously through an outer skin surface of a patient to a nerve within the patient at a target region within the patient beneath the outer skin surface such that the electric field is able to modulate the nerve and thereby treat at least one of a disorder or a disease of the patient.
