Abstract
Various aspects relate to a device which, in various embodiments, comprises a header, a neural stimulator, a detector and a controller. The header includes at least one port to connect to at least one lead, and includes first and second channels for use to provide neural stimulation to first and second neural stimulation sites for a heart. The controller is connected to the detector and the neural stimulator to selectively deliver a therapy based on the feedback signal. A first therapy signal is delivered to the first neural stimulation site to selectively control contractility and a second therapy signal is delivered to the second neural stimulation site to selectively control one of a sinus rate and an AV conduction. Other aspects and embodiments are provided herein.
Claims20
A method of delivering a therapy to treat heart failure, the method comprising:
- delivering myocardial pacing;
- and
- delivering neural stimulation therapy during the myocardial pacing, wherein delivering the neural stimulation includes stimulating an SVC-AO cardiac fat pad to change ventricular contractility of the heart without changing heart rate or inducing an arrhythmia, the SVC-AO fat pad being located proximate to a junction between a superior vena cava and an aorta.
A method of delivering a post-myocardial infarction therapy in a patient, the method comprising:
- delivering a therapy after the patient experiences a myocardial infarction, wherein delivering the therapy includes delivering a neural stimulation therapy to stimulate an SVC-AO cardiac fat pad to change ventricular contractility of the heart without changing heart rate or inducing an arrhythmia, the SVC-AO fat pad being located proximate to a junction between a superior vena cava and an aorta.
A method of delivering a therapy to treat tachycardia, the method comprising:
- detecting a tachycardia;
- and
- delivering a neural stimulation therapy in response to the detected tachycardia, wherein delivering the neural stimulation therapy includes stimulating an SVC-AO cardiac fat pad to change ventricular contractility of the heart without changing heart rate or inducing an arrhythmia, the SVC-AO fat pad being located proximate to a junction between a superior vena cava and an aorta.
A method of delivering a therapy, comprising:
- delivering a neural stimulation therapy, wherein delivering the neural stimulation therapy includes stimulating an SVC-AO cardiac fat pad to change ventricular contractility of the heart without changing heart rate or inducing an arrhythmia, the SVC-AO fat pad being located proximate to a junction between a superior vena cava and an aorta, wherein the therapy includes a therapy to treat heart failure, a post-myocardial infarction therapy, or a therapy to treat tachycardia.
