First Claim
Patent Images
1. An implantable neurostimulation system, comprising:
- a first VNS electrode assembly configured to couple to and deliver electrical stimulation to a vagus nerve; and
a first CBS electrode assembly configured to couple to and deliver electrical stimulation to carotid baroreceptors; and
a pulse generator comprising;
a vagus nerve stimulation (VNS) subsystem comprising VNS stimulation circuitry;
an implantable carotid baroreceptor stimulation (CBS) subsystem comprising CBS stimulation circuitry; and
a control system that;
activates the VNS subsystem and controls the VNS stimulation circuitry to deliver electrical energy to the first VNS electrode assembly according to a first set of parameters; and
activates the CBS subsystem and controls the CBS stimulation circuitry to deliver electrical energy to the first CBS electrode assembly according to a second set of parameters different than the first set of parameters.
