Abstract
A system and method of neuromodulation adjunct (add-on) therapy for atrial fibrillation, refractory hypertension, and inappropriate sinus tachycardia comprises an implantable lead-receiver and an external stimulator. Neuromodulation is performed using pulsed electrical stimulation. The external stimulator contains a power source, controlling circuitry, a primary coil, and predetermined programs. The primary coil of the external stimulator inductively transfers electrical signals to the implanted lead-receiver, which is also in electrical contact with a vagus nerve. The external stimulator emits electrical pulses to stimulate the vagus nerve according to a predetermined program. In a second mode of operation, an operator may manually override the predetermined sequence of stimulation. The external stimulator may also be equipped with a telecommunications module to control the predetermined programs remotely.
