Baroreflex modulation to gradually decrease blood pressure
First Claim

1. A method, comprising:
- sensing blood pressure using an implantable medical device; and
using a programmed algorithm in the implantable medical device, progressively lowering blood pressure from a start time and over a period of time following the start time so that the sensed blood pressure reaches a target blood pressure,wherein progressively lowering the sensed blood pressure includes delivering neural stimulation that is effective in lowering blood pressure, and using the programmed algorithm to adjust an intensity of the neural stimulation during the period of time to cause the blood pressure to be progressively lowered toward the target pressure during the period of time so that the sensed blood pressure reaches the target blood pressure after the period of time.

Abstract
An aspect of the present subject matter relates to a baroreflex stimulator. An embodiment of the stimulator includes a pulse generator to provide a baroreflex stimulation signal through an electrode, and a modulator. The modulator modulates the baroreflex stimulation signal to increase the baroreflex stimulation therapy by a predetermined rate of change to lower systemic blood pressure to a target pressure. Other aspects are provided herein.

17. A method, comprising:
-
sensing blood pressure; determining cardiac output; and implementing a programmed algorithm in an implantable medical device to control an intensity of neural stimulation delivered by the implantable medical device to gradually lower blood pressure with time from a start, time and over a period of time following the start time to reach a programmed target blood pressure, wherein the programmed algorithm adjusts the intensity of the neural stimulation and determining the rate of change as a function of the sensed blood pressure, the programmed target blood pressure and the cardiac output. - View Dependent Claims (18, 19, 20)
