1. Apparatus for treating a condition, comprising:
- a set of one or more electrodes, adapted to be applied to one or more respective sites in a vicinity of a stomach of a patient; and
a control unit, adapted to drive the electrode set to apply an Excitable-Tissue Control (ETC) signal to the sites, configured such that application thereof decreases a cross-sectional area of at least a portion of the stomach,wherein the control unit is adapted to configure a timing parameter of the ETC signal responsive to timing of natural gastric electrical activity.

Abstract
Apparatus is provided for treating a condition such as obesity. The apparatus includes a set of one or more electrodes, which are adapted to be applied to one or more respective sites in a vicinity of a body of a stomach of a patient. A control unit is adapted to drive the electrode set to apply to the body of the stomach a signal, configured such that application thereof increases a level of contraction of muscle tissue of the body of the stomach, and decreases a cross-sectional area of a portion of the body of the stomach for a substantially continuous period greater than about 3 seconds.

16. Apparatus for treating a condition, comprising:
-
exactly one set of one or more electrodes, adapted to be applied to one or more respective sites in a vicinity of a body of a stomach of a patient, the one or more respective sites generally arranged in a plane substantially perpendicular to a longitudinal axis of the stomach; and a control unit, adapted to drive the electrode set to apply to the body of the stomach, substantially in the plane, a signal configured such that application thereof increases a level of contraction of muscle tissue of the body of the stomach, and decreases a cross-sectional area of a portion of the body of the stomach substantially in the plane for a substantially continuous period greater than about 3 seconds. - View Dependent Claims (17, 18, 19)
