Abstract
An active implantable medical device includes a VNS pulse bursts generator for stimulation of the vagus nerve according to several selectable configurations. The device may further include a sensor of the current activity level of the patient. The generator is controlled on the activity signal via a classifier determining the class of the current level of activity among a plurality of classes of activity. A controller selects a configuration of VNS therapy depending on the class of activity thus determined. Limits of the activity classes are dynamically changeable by a calibration module that conducts a historical analysis of the successive current activity levels over a predetermined analysis period. The calibration module can prepare a histogram of the historical analysis, and can define the limits of the activity classes depending on the outcome of the historical analysis and the histogram.
