  • Publication number: 20140012348
    Abstract: The disclosure is directed to techniques for delivering electrical stimulation therapy to support obesity management. The electrical stimulation therapy is configured to cause at least partial gastric distention. Gastric distention tends to induce a sensation of fullness and thereby discourages excessive food intake by the patient. The electrical stimulation therapy may be delivered to the gastrointestinal tract of the patient by electrodes deployed by one or more implantable leads coupled to an electrical stimulator. The electrical stimulator delivers stimulation pulses having a pulse width in a range found to be effective in causing gastric distention.

  • Patent number: 8565885
    Abstract: The disclosure is a method of treatment for obesity, in an individual in need thereof comprising positioning stimulatory electrodes in the distal small intestines or ileum, and administering electrical stimulation in trains of pulses or repetitive pulses, where the electrical stimulation is effective, at least in part in, stimulating the vagal afferent and efferent activity, of the distal small intestines or ileum, in the individual. The stimulation of the vagal afferent and efferent activity leads to the regulation of the ileal brake. Specifically, the electrical stimulation is provided in trains of pulses. Also, described is a method of treatment for functional gastrointestinal disease by ileal electrical stimulation. Further this invention provides a method of treatment for an eating disorder comprising administering ileal electrical stimulation effective, at least in part, in stimulating the vagal and sympathetic pathways.

  • Patent number: 8467874
    Abstract: The disclosure provides a method of treatment for obesity, in an individual in need thereof, by administering electrical stimulation at dual sites in the gastrointestinal tract. The electrical stimulations are administered by positioning bipolar stimulatory electrodes in contact with the gastric and dudenol cavities, along afferent vagal neural pathways, in the gastrointestinal tract. The electrical stimulations thus administered, activate the vagal afferents associated with the gastric and dudenol sites in the gastrointestinal tract. The activation of vagal afferents modulates the gastrointestinal peptide satiety hormones. Further, the disclosure provides a method of treatment for eating disorders, in an individual in need thereof, by administering electrical stimulation at dual sites, along afferent vagal neural pathways, in the gastrointestinal tract.

  • Patent number: 8211941
    Abstract: One of the major disabling symptoms of gastroparesis is nausea and vomiting which can be difficult to control with currently available treatments. It is postulated that signaling of gastrointestinal causes of nausea starts with activation of vagal afferent nerves that trigger the central emetic pathway. Most vagal afferent nerves are unmyelinated C-fibers, many of which express the vanilloid receptor TRPV1 and respond to capsaicin. Resiniferatoxin is a very potent capsaicin analogue that has a much more favorable ratio of desensitization to excitation than capsaicin leading to more effective desensitization without irritation. The present invention describes methods of alleviating acute or chronic nausea, vomiting by the administration of resiniferatoxin.
