Patent number: 8000792Abstract: A body-worn device for a fast healing of incontinence by building up the necessary durable behavioral conditioning, which provides the brain with the necessary proper control over the respective sphincters. The device is based on two different nerve mechanisms: a first electrical pulse stops the release of bodily wastes by a simple local reflex, arousing simultaneously the brain and preparing it to respond to a second, behavioral conditioning causing electric pulse, which follows within two seconds (i.e. still during the phasic period of the cortical learning process), strong enough to cause an unpleasant sensation, which the brain connects with the just begun incontinent release of bodily waste and acquires after only a few applications as a durable adversive behavioral conditioning. This shortens the healing period from many months to only a few days. The device is easily adjustable to the individual sensitivity of the involuntarily wetting or soiling person.Type: GrantFiled: April 28, 2009Date of Patent: August 16, 2011Inventors: George D.

Publication number: 20110166499Abstract: Methods and apparatus are provided for inducing, monitoring and controlling renal neuromodulation using a pulsed electric field to effectuate electroporation or electrofusion. In some embodiments, tissue impedance, conductance or conductivity may be monitored to determine the effects of pulsed electric field therapy, e.g., to determine an extent of electroporation and its degree of irreversibility. Pulsed electric field electroporation of tissue causes a decrease in tissue impedance and an increase in tissue conductivity. If induced electroporation is reversible, upon cessation of the pulsed electric field, tissue impedance and conductivity should approximate baseline levels; however, if electroporation is irreversible, impedance and conductivity changes should persist. Thus, monitoring of impedance or conductivity may be utilized to determine the onset of electroporation and to determine the type or extent of electroporation.Type: ApplicationFiled: March 7, 2011Publication date: July 7, 2011Applicant: Ardian, Inc.Inventors: Denise Demarais, Nicolas Zadno

Patent number: 7873417Abstract: Methods and apparatus are provided for pulsed electric field neuromodulation via an intra-to-extravascular approach, e.g., to effectuate irreversible electroporation or electrofusion, necrosis and/or inducement of apoptosis, alteration of gene expression, changes in cytokine upregulation and other conditions in target neural fibers. In some embodiments, the ITEV PEF system comprises an intravascular catheter having one or more electrodes configured for intra-to-extravascular placement across a wall of patient's vessel into proximity with target neural fibers. With the electrode(s) passing from an intravascular position to an extravascular position prior to delivery of the PEF, a magnitude of applied voltage or energy delivered via the electrode(s) and necessary to achieve desired neuromodulation may be reduced relative to an intravascular PEF system having one or more electrodes positioned solely intravascularly.Type: GrantFiled: November 11, 2009Date of Patent: January 18, 2011Assignee: Ardian, Inc.Inventors: Denise Demarais, Benjamin J.

Patent number: 7869884Abstract: Devices and methods of non-surgically providing vagus nerve therapy trans-esophageally to treat a variety of medical conditions are disclosed herein. In an embodiment, an implantable medical device comprises a support member having an outer surface. The support member is adapted to engage the inner wall of an esophagus. The IMD also comprises at least one electrode disposed on the outer surface of the support member. The at least one electrode is capable of applying a trans-esophageal electrical signal to the vagus nerve through the wall of the esophagus from the inner lumen thereof. The implantable medical device further comprises a signal generator coupled to the support member and to the at least one electrode. The signal generator causes the at least one electrode to apply an electrical signal to the vagus nerve to treat a medical condition.Type: GrantFiled: April 26, 2007Date of Patent: January 11, 2011Assignee: Cyberonics, Inc.Inventors: Timothy L. Scott, Steven E. Maschino

Publication number: 20110004266Abstract: A method and device for electrically stimulating one or more structures in the gastrointestinal tract as described. The one or more structures are preferably selected from the upper esophageal sphincter, the esophagus and gastric fundus. The method may involve the step of arranging a plurality of stimulating electrodes adjacent one or more structures which may further include the lower esophageal sphincter, the stomach, the pyloric sphincter, the small intestine, the colon and the vagus. The method and device may further include sensing electrodes to detect change in one or more physiological parameters in the gastrointestinal tract and modulate the stimulating electrodes in response to the change. The device comprises a pulse generator, a power source, a plurality of stimulating electrode set, one or more sensing electrodes and means for varying activity of the stimulating electrodes in response to change detected in the gastrointestinal tract. The method and device may be used to treat obesity and/or GERD.Type: ApplicationFiled: May 6, 2010Publication date: January 6, 2011Inventor: Virender K. Sharma

Patent number: 7856273Abstract: A method and apparatus for stimulating a portion of a vagus nerve of a patient to treat a gastrointestinal disorder is provided. At least one electrode is coupled to at least one portion of a vagus nerve of the patient. The portion of the a vagus nerve may include an esophageal plexus, a myenteric plexus of aurbach, a submucous plexus of the meissner, a principal nerve of the lesser curvature of the stomach, and a gastric branch of said vagus nerve. An electrical signal is applied to the portion of the vagus nerve using the electrode to treat the gastrointestinal disorder.Type: GrantFiled: July 28, 2005Date of Patent: December 21, 2010Assignee: Cyberonics, Inc.Inventors: Steven E. Maschino, Steven M. Parnis, William R. Buras, Albert W. Guzman

Publication number: 20100305468Abstract: Apparatus (18, 18?) is provided, which includes one or more fundic sensors (74), configured to be applied to a fundus of a subject (10), and to generate a fundic signal. The apparatus further includes a control unit (90), which is configured to make a tentative determination of ingestion by the subject (10), determine fundic impedance responsively to the fundic signal, and calculate a duration of a period during which the fundic impedance rose during the tentatively-determined ingestion. Upon finding that the duration is less than a fundic rise duration threshold value, the control unit (90) determines that the tentative determination of ingestion is a false positive. Other embodiments are also described.Type: ApplicationFiled: May 11, 2008Publication date: December 2, 2010Applicant: METACURT LTD.Inventors: Shai Policker, Aharon Grossman, Anat Kliger

Patent number: 7844338Abstract: A method for treating at least one of a plurality of disorders characterized at least in part by vagal activity includes positioning an electrode around a body organ innervated by the vagus. An electrical signal is applied to the electrode to modulate vagal activity. The electrical signal is applied at a frequency selected for the signal to create a neural conduction block to the vagus with the neural conduction block selected to at least partially block nerve impulses on the vagus. The application of the electrical signal is discontinued. The application of the signal and the discontinuing of the signal are repeated with durations of the discontinuing and the application selected to treat the disorder.Type: GrantFiled: June 30, 2004Date of Patent: November 30, 2010Assignee: EnteroMedics Inc.Inventors: Mark B.
