Nerve stimulation and blocking for treatment of gastrointestinal disorders
First Claim
1. A method for treating at least one of a plurality of disorders of a gastrointestinal tract of a patient where the disorders are characterized at least in part by hyper-tonal vagal activity the method comprises applying at least one electrode adapted to be placed on a vagus nerve below a vagal innervation of the heart;
- delivering an electrical signal to the vagus nerve having a frequency of at least 500 Hz and having at least one parameter selected to i) at least partially downregulate efferent or afferent nerve activity of the vagus nerve, and ii) allow at least partial recovery of the nerve activity following discontinuation of the electrical signal.

Abstract
At least one of a plurality of gastrointestinal disorders is treated by stimulating an enteric nervous system of a patient to enhance a functional tone of the enteric nervous system. A treatment includes electrically stimulating a vagus nerve of the patient at a stimulation site proximal to at least one site of vagal innervation of a gastrointestinal organ. The electrical stimulation includes applying a stimulation signal at the stimulation site. An optional proximal electrical blocking signal is applied to the vagus nerve at a proximal blocking site proximal to the stimulation site. The proximal blocking signal is selected to at least partially block nerve impulses at the proximal blocking site.
