Apparatus for treating patients with motility disorders applies a modulating signal to the patient's vagus nerve to stimulate or inhibit neural impulses and produce excitatory or inhibitory neurotransmitter release by the vagus nerve according to the specific nature of the motility disorder. The apparatus includes a neurostimulator which can be activated to generate an electrical output signal. The neurostimulator is responsive to the sensing of a selected event having occurred which is indicative of the need for treatment of the motility disorder, and includes an activation element which responds to sensing of that event to activate the neurostimulator, and a lead with an electrode array to apply the electrical output signal as the modulating signal to the patient's vagus nerve. Certain parameters of the output signal are programmable, and the neurostimulator can be calibrated according to the specific patient and the specific motility disorder being treated. One form of sensor detects the impedance of a selected part of the gastrointestinal system to detect the presence of excessive contractions in that part as an indication of hypermotility whether or not food has been consumed by the patient within a preset interval of time, and inadequate contractions in that part as an indication of hypomotility if food was consumed by the patient within a preset interval of time.

Treatment of motility disorders by nerve stimulation

The treatment, control or prevention of medical, psychiatric or neurological disorders may be accomplished by application of modulating electric signals to one or both of a patient's trigeminal and glossopharyngeal nerves. The disorders treatable, controllable or preventable by such nerve stimulation include voluntary and involuntary disorders, migraine, epileptic seizure, motor disorders, Parkinson's disease, cerebral palsy, spasticity, chronic nervous illnesses and involuntary movement; pancreatic endocrine disorders including diabetes and hypoglycemia; dementia including cortical, subcortical, multi-infarct, Alzheimer's disease and Pick's disease; sleep disorders including central sleep apnea, insomnia and hypersomnia; eating disorders including anorexia nervosa, bulimia and compulsive overeating; and neuropsychiatric disorders including schizophrenia, depression and borderline personality disorder.

Method and apparatus for treating and controlling migraine by selectively applying a predetermined electrical signal to the patient's vagus nerve for stimulation thereof to alleviate the migraine attack. The signal is a pulse waveform having parameters programmed to desynchronize the patient's EEG if paroxysmal activity is detected in the EEG, or to synchronize the EEG if low voltage fast wave activity is detected. Alternatively, the application of the stimulating signal to the vagus nerve may be initiated manually by the patient upon recognition of the onset of a migraine attack. The neurostimulator device implanted in the patient to generate the appropriate signal has a power down circuit to conserve battery power between migraine episodes.

A method of inhibiting the release of a proinflammatory cytokine in a cell is disclosed. The method comprises treating the cell with a cholinergic agonist. The method is useful in patients at risk for, or suffering from, a condition mediated by an inflammatory cytokine cascade, for example endotoxic shock. The cholinergic agonist treatment can be effected by stimulation of an efferent vagus nerve fiber, or the entire vagus nerve.

Inhibition of inflammatory cytokine production by cholinergic agonists and vagus nerve stimulation

A method and apparatus for monitoring and obtaining actual bio-electrical characteristics of a subject under predetermined conditions of evoked response stimuli, and by interaction with a computer, applying cutaneous electrical stimulation to the subject, using a signal generator to modify current amplitude and frequency in a direction to achieve bio-electrical characteristics in the subject related to the actual bio-electrical characteristics monitored. The signal generator uses a sinusoidal waveform output, with battery power passed through a transformer to power a transconductance amplifier to obtain constant current output despite resistance changes in the line with the subject, and with the transformer not placed in the signal path of the sinusoidal waveform. The signal may be obtained from a sinusoidal oscillator of wide frequency having switched integrator sections connected to an inverting amplifier, pulse generator and gating.
