Abstract
A neural stimulation system senses autonomic activities and applies neural stimulation to sympathetic and parasympathetic nerves to control autonomic balance. The neural stimulation system is capable of delivering neural stimulation pulses for sympathetic excitation, sympathetic inhibition, parasympathetic excitation, and parasympathetic inhibition.
Claims25
A method for delivering a therapy to a patient, comprising:
- applying inhibition to afferent nerve fibers extending from chemoreceptors to the central nervous system of the patient, wherein applying inhibition includes inhibiting nerve traffic in the afferent nerve fibers to provide a therapeutic effect.
A method for delivering a therapy, comprising:
- sensing one or more physiological parameters indicative of increased sympathetic tone;
- and
- inhibiting nerve traffic in the sympathetic afferent nerve fibers from chemoreceptors in a carotid body to decrease sympathetic tone in response to the increased sympathetic tone.
A method for delivering a therapy, comprising:
- delivering an electrical therapy to a nerve in a sympathetic nervous system;
- sensing nerve traffic associated with chemoreceptors in a carotid body;
- and
- controlling the delivery of the electrical therapy using the detected nerve traffic.
1 more element
A neural stimulation system, comprising:
- a stimulation output circuit configured to deliver stimulation to inhibit nerve traffic in sympathetic afferent nerve fibers extending from chemoreceptors in a carotid body;
- an autonomic balance monitoring circuit configured detect a signal indicative of autonomic activities;
- and
- a stimulation control circuit coupled to the stimulation output circuit and the autonomic balance monitoring circuit, the stimulation control circuit configured to control the delivery of the stimulation using the detected signal indicative of autonomic activities.
