DEVICES AND METHODS FOR NON-INVASIVE VAGAL NERVE STIMULATION

Systems and methods are provided for modulating one or more nerves within patients. A method comprises generating a signal comprising an electrical impulse and contacting an interface with an outer skin surface of a patient. The electrical impulse is delivered from one or more electrode(s) through the interface and the outer skin surface of the patient to a vagus nerve, thereby modulating the vagus nerve sufficiently to treat a medical condition. The one or more electrode(s) are spaced from the interface by a distance of about 0.25 to about 4 times an outer dimension of the interface.

METHOD AND DEVICE FOR STIMULATING MYELINATED AND UNMYELINATED SMALL DIAMETER VAGAL NEURONS

A method for stimulating vagal neurons as demonstrated by generation of action potentials on these same neurons, wherein electrical pulse trains are periodically applied to electrodes implanted on the anterior and posterior vagus nerve at an entrance of a diaphragm, wherein each electrical pulse train is formed by a plurality of monophasic pulses having a frequency of at least 13.0 kHz.

20170304628 · 2017-10-26 ·

An implantable pulse generator system includes a nerve stimulation unit providing vagal nerve stimulation (VNS) pulses; an autonomic tone sensor which determines the patient's autonomic status; and a control unit connected to the nerve stimulation unit and the autonomic tone sensor. The control unit controls the nerve stimulation unit to generate VNS with varying intensity, depending on the autonomic status (which is evaluated in a moving window). The control unit gradually increases VNS intensity when the autonomic status indicates a shift toward more sympathetic dominance, and it gradually decreases VNS intensity when the autonomic status indicates a shift toward more parasympathetic dominance, wherein the gradual increase and the gradual decrease of the VNS intensity follow two different paths.

Cranial nerve stimulation to treat seizure disorders

A method includes applying, by an implantable medical device (IMD), stimulation to a cranial nerve of a patient responsive to a determination that a level of synchrony between neural activity of one or more regions of an autonomic nervous system of the patient and one or more regions of a central nervous system of the patient falls below a first threshold and discontinuing the application of stimulation by the IMD when the level of synchrony exceeds a second threshold.

Electrical treatment of bronchial constriction
