Patent number: 8340772Abstract: Methods and devices for improved neurostimulation to treat obesity. Some methods include measuring temperature increases in Brown Adipose Tissue (BAT) during intraoperative test stimulations to determine the proper nerve electrode placement for implantation. Methods can include determining the side of the patient having the most BAT, and stimulating preferentially on that right or left side. The BAT maybe used to burn fat by stimulating the sympathetic nervous system innervating the BAT deposits.Type: GrantFiled: May 5, 2010Date of Patent: December 25, 2012Assignee: Advanced Neuromodulation Systems, Inc.Inventors: Abhi Vase, Johann Neisz

Patent number: 8340760Abstract: A method is described for the treatment of obesity or other disorders, by electrical activation or inhibition of the sympathetic nervous system. This activation or inhibition can be accomplished by electrically stimulating the greater splanchnic nerve or other portion of the sympathetic nervous system using an implantable pulse generator. This nerve activation can result in reduced food intake and increased energy expenditure. Reduced food intake may occur through a variety of mechanisms that reduce appetite and cause satiety. Increased adrenal gland hormone levels will result in increased energy expenditure. Fat and carbohydrate metabolism, which are also increased by sympathetic nerve activation, will accompany the increased energy expenditure.Type: GrantFiled: September 12, 2011Date of Patent: December 25, 2012Assignee: Advanced Neuromodulation Systems, Inc.Inventor: John D Dobak, III

Patent number: 8321030Abstract: Methods and devices for delivering electrical stimulation to the sympathetic nervous system in response to the onset of eating. In some methods, swallowing is detected which then initiates a dose of stimulation which can vary in intensity, frequency, or both over the dose length. In some methods, the dose length is between about one quarter hour and one hour. The dose frequency may increase, hold steady, then decrease over the dose duration so as to mimic the response of the gut stretch and nutrient receptors to receiving food. The dose can drive biomarkers indicative of eating, for example glucagon, glucose, FFA or glycerol to at least about half of their normal post eating levels and then stop so as to retain stimulation effectiveness for subsequent doses and to prolong battery life.Type: GrantFiled: April 20, 2010Date of Patent: November 27, 2012Assignee: Advanced Neuromodulation Systems, Inc.Inventors: Jeremy Maniak, Johann Neisz
