1. A method of treating patients suffering from refractory hypertension, comprising the steps of:

  • implanting a neurostimulating device constructed and arranged to generate a stimulating electrical signal as an output thereof in the body of the patient operative to sense a prescribed event indicative of an imminent need for treatment of the refractory hypertension, said prescribed event being the patient'"'"'s blood pressure exceeding a programmed threshold level, the step of implanting including connecting said output directly to the vagus nerve of the patient for application of said stimulating electrical signal thereto, andprogramming the device to automatically respond to the sensed occurrence of the prescribed event with application of a stimulating electrical signal having programmed electrical parameters to the patient'"'"'s vagus nerve to modulate the electrical activity of the vagus nerve in a manner to alleviate the refractory hypertension.
