Vagus nerve stimulation (VNS) is a medical treatment that involves delivering electrical impulses to the vagus nerve. It is used as an add-on treatment for certain types of intractable epilepsy and treatment-resistant depression. Frequent side effects include coughing and shortness of breath. Serious side effects may include trouble talking and cardiac arrest.

Vagal nerve stimulation techniques for treatment of epileptic seizures
InactiveUS6920357B2ElectrotherapyDiagnostic recording/measuringImplantable ElectrodesCardiac pacemaker electrode
The present invention uses electrical stimulation of the vagus nerve to treat epilepsy with minimized or no effect on the heart. Treatment is carried out by an implantable signal generator, one or more implantable electrodes for electrically stimulating a predetermined stimulation site of the vagus nerve, and a sensor for sensing characteristics of the heart such as heart rate. The heart rate information from the sensor can be used to determine whether the vagus nerve stimulation is adversely affecting the heart. Once threshold parameters are met, the vagus nerve stimulation may be stopped or adjusted. In an alternative embodiment, the invention may include a modified pacemaker to maintain the heart in desired conditions during the vagus nerve stimulation. In yet another embodiment, the invention may be simply a modified pacemaker having circuitry that determines whether a vagus nerve is being stimulated. In the event that the vagus nerve is being stimulated, the modified pacemaker may control the heart to maintain it within desired conditions during the vagus nerve stimulation.

A system and method for treating nausea and vomiting are provided, including one or more electrodes (10, 12) applied on or under the skin, the electrodes being connected to an external current source (34). The electrodes can be implanted under the skin and connect to internal stimulator electronics (22), which can form a magnetic inductive link to the external current source (34). Alternatively, the electrodes can be placed on the skin and directly linked by wires to the external current source. As a further alternative, the vagus nerve can be directly stimulated in the neck, or the esophagus, stomach, duodenum, or intestines can be directly stimulated by magnetic stimulation. The electrodes can stimulate the vagus nerve in the neck to reduce nausea and vomiting, or can be arranged near the chest or abdomen, so as to stimulate the esophagus, stomach, duodenum or intestines. Because the current source is provided outside the body, it is not necessary to implant batteries or another power supply in the body.

Systems and Methds for Use by an Implantable Medical Device for Controlling Vagus Nerve Stimulation Based on Heart Rate Reduction Curves and Thresholds to Mitigate Heart Failure
InactiveUS20100114227A1Slow down heart rateMitigate heart failureHeart stimulatorsMaximum levelCardiac muscle
Systems and techniques are provided for controlling vagus nerve stimulation (VNS) delivered by an implantable medical device for mitigating heart failure in a patient. In one mode, VNS therapy is set to levels just below a heart rate reduction threshold so as to deliver VNS near the highest stimulation levels that can be achieved without reducing patient heart rate. In this manner, a maximum level of heart failure mitigation can be achieved via VNS therapy without incurring the potentially adverse consequences of inducing bradycardia within the patient. In another mode, VNS therapy is instead controlled to deliver VNS above the threshold so as to mitigate heart failure while also selectively reducing heart rate, as may be appropriate in patients susceptible to cardiac ischemia. A controlled heart rate reduction curve may additionally or alternatively be determined for use in achieving target amounts of heart rate reduction.
