Electric modulation of sympathetic nervous system
First Claim
1. A method for inducing weight loss in a patient, comprising:
- providing a pulse generator that emits electrical pulses in a programmable stimulation pattern;
wherein the stimulation pattern is programmable to achieve weight loss in the patient from electrical activation of a splanchnic nerve of the patient; and
wherein the stimulation pattern is further programmable to keep the patient'"'"'s blood pressure within safe limits during the electrical activation of the splanchnic nerve;
electrically activating the splanchnic nerve of the patient with said pulse generator using said stimulation pattern so as to achieve weight loss and keep the patient'"'"'s blood pressure within safe limits;
wherein the splanchnic nerve is selected from the group consisting of the greater splanchnic nerve, the lesser splanchnic nerve, and the least splanchnic nerve; and
programming said stimulation pattern so as to achieve weight loss in the patient and so as to keep the patient'"'"'s blood pressure within safe limits during electrical activation of the splanchnic nerve.

Abstract
A method 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.
