Embodiment Construction

[0056] With reference now to the various drawing figures in which identical elements are numbered identically throughout, a description of the preferred embodiment of the present invention will now be described.

[0057] A. Invention of Parent Application

[0058] FIGS. 1 and 2 and the description which follow are from the aforementioned U.S. patent application Ser. No. 10 / 358,093 filed Feb. 3, 2003 filed Feb. 3, 2003 and entitled "Method and Apparatus for Treatment of Gastroesophageal Disease (GERD)".

[0059] With initial reference to FIG. 1, a gastric emptying feedback loop is shown schematically for ease of illustration. The feedback loop illustrates a patient's stomach S which is provided with food from the esophagus E. A lower esophageal sphincter LES is shown positioned between the esophagus E and the stomach S. The lower esophageal sphincter normally provides control of reflux of stomach contents into the esophagus E.

[0060] On a proximal or lower end of the stomach S the stomach disc...

Abstract

A treatment apparatus and method have a stimulation electrode adapted for placement on a nerve of a patient at a stimulation site and a stimulation signal generator for generating a stimulation signal at the stimulation electrode and selected to electrically stimulate a nerve to induce bi-directional propagation of nervous impulses in a stimulated nerve. The apparatus includes a blocking member for placement on the nerve at a blocking site and creating localized conditions at the blocking site that at least partially diminish transmission of nerve impulses past the blocking site.

Description

I. CROSS-REFERENCE TO RELATED APPLICATION[0001] The present application is a continuation-in-part application of U.S. patent application Ser.
