US Patent 11654277 Nerve stimulation devices and methods

Systems and methods for treating diseases and disorders in a patient are provided. A device comprises a stimulator comprising an electrode and an energy source. The energy source is configured to generate an electrical impulse and transmit the electrical impulse to the electrode through an outer skin surface to a vagus nerve of the patient. The device further comprises a sensor for detecting a physiological parameter of a patient's heart and a controller coupled to the stimulator and the sensor and configured to activate the stimulator based on the physiological parameter to cause the stimulator to generate the electrical impulse. In some aspects, the electrical impulse is sufficient to modulate the vagus nerve to treat a cardiac arrhythmia of the patient.
