Abstract:
1. An implantable medical device, comprising: at least one lead to position a first electrode operationally proximate to a first neural stimulation site for a heart for use in stimulating the first neural stimulation site and to position a second electrode operationally proximate to a second neural stimulation site for the heart for use in stimulating the second neural stimulation site, the at least one lead including: a neural stimulator connected to the first channel to selectively apply the first neural stimulation therapy signal to the first neural stimulation site using the first electrode, and connected to the second channel to selectively apply the second neural stimulation therapy signal to the second neural stimulation site using the second electrode; a detector to receive at least one sensed signal indicative of at least one sensed physiological parameter, the detector to generate at least one feedback signal based on the at least one sensed signal; a controller connected to the detector and to the neural stimulator to implement a neural stimulation therapy based on the feedback signal to change ventricular contractility of the heart without changing heart rate or inducing an arrhythmia and to change the sinus rate of the heart without changing AV conduction time or to change the AV conduction time of the heart without changing the sinus rate, the controller to implement the neural stimulation therapy to deliver the first neural stimulation therapy signal through the first channel to the first neural stimulation site to locally modulate autonomic tone to change contractility, and the second neural stimulation therapy signal through the second channel to the second neural stimulation site to locally modulate autonomic tone to change one of the sinus rate and the AV conduction.
