Abstract
Systems and methods are provided for delivering vagus nerve stimulation and carotid baroreceptor stimulation to patients for treating chronic heart failure and hypertension. The vagus nerve stimulation and carotid baroreceptor stimulation therapies may be provided using a single implantable pulse generator, which can coordinate delivery of the therapies.
Claims16
A method of operating an implantable neurostimulation system, comprising:
- delivering a vagus nerve stimulation (VNS) therapy to a vagus nerve of a patient for the treatment of chronic heart failure, according to a first set of parameters, with a VNS subsystem comprising VNS stimulation circuitry of a pulse generator;
- delivering a carotid baroreceptor stimulation (CBS) therapy to carotid baroreceptors of the patient for the treatment of hypertension, according to a second set of parameters different from the first set of parameters, with a CBS subsystem comprising CBS stimulation circuitry of the pulse generator, wherein at least a portion of the CBS therapy is provided using the CBS subsystem during a same time during which at least a portion of the VNS therapy is provided using the VNS subsystem;
- determining an activity level of the patient;
- and
- temporarily suspending delivery of the CBS therapy during a period of increased activity level of the patient.
A non-transitory computer-readable medium having instructions stored thereon that are executable by a processor of an implantable neurostimulation system to cause the processor to perform operations comprising:
- delivering a vagus nerve stimulation (VNS) therapy to a vagus nerve of a patient, according to a first set of parameters, with a VNS subsystem comprising VNS stimulation circuitry of a pulse generator of the implantable neurostimulation system;
- delivering a carotid baroreceptor stimulation (CBS) therapy to carotid baroreceptors of the patient, according to a second set of parameters different from the first set of parameters, with a CBS subsystem comprising CBS stimulation circuitry of the pulse generator, wherein at least a portion of the CBS therapy is provided using the CBS subsystem during a same time during which at least a portion of the VNS therapy is provided using the VNS subsystem;
- determining an activity level of the patient and
- temporarily suspending delivery of the CBS therapy during a period of increased activity level of the patient.
