Patent ID: 7310557

Claim:
A method of selecting one or more electrodes from a plurality of electrodes for providing an electrical stimulation signal to a vagus nerve, comprising: (a) providing an implantable gastric band having a plurality of stimulation electrodes and a plurality of sensing electrodes, each of said stimulation and sensing electrodes having an address from which its position on said band is known; (b) surgically coupling said implantable gastric band to at least a portion of the patient's gastrointestinal tract, said step comprising electrically coupling at least one of said plurality of stimulation electrodes and at least one of said plurality of sensing electrodes to a vagus nerve on said at least a portion of the gastrointestinal tract; (c) generating an electrical stimulation test signal capable of inducing an action potential on a vagus nerve if applied thereto; (d) applying said electrical stimulation test signal to at least one of said plurality of stimulating electrodes; (e) sensing for an induced action potential on a vagus nerve using at least one of said plurality of sensing electrodes; and (f) if an induced action potential is sensed, (1) using said addresses to identify at least a first sensing electrode sensing said induced action potential (2) using said addresses to identify the address of at least a first stimulation electrode comprising the electrode among said plurality of stimulation electrodes nearest said first sensing electrode.
