Abstract
A device embodiment is configured to deliver vagal stimulation therapy (VST) to a vagus nerve of a patient. The device embodiment includes a neural stimulator, an implantable pressure sensor, and a pressure analyzer. The neural stimulator is configured to deliver the VST to the vagus nerve in a cervical region of the patient. The implantable pressure sensor is configured to be implanted in the cervical region and to detect pressure changes in the cervical region caused by laryngeal vibrations. The pressure sensor is configured to generate sensed pressure values. The pressure analyzer is configured to analyze the sensed pressure values generated by the pressure sensor. The analyzer is configured to detect laryngeal vibrations or cough from the sensed pressure values.
