Abstract
Neural Gastric Electrical Stimulation (NGES) is a new method for invoking gastric contractions under microprocessor control. However, optimization of this technique using feedback mechanisms to minimize power consumption and maximize effectiveness has been lacking. An apparatus and method are provided for inducing controlled gastro paresis. The apparatus comprises a contraction sensor, a stomach contraction generator, and a controller. The contraction sensor is responsive to circumferential contractions of the stomach, and outputs a signal indicative of a circumferential contraction. The stomach contraction generator induces a circumferential contraction upon receipt of an electrical signal from the controller. The controller sends the electrical signal to the generator upon receipt of the output signal from the sensor. The method comprises the steps of sensing a circumferential contraction of the stomach, and invoking a circumferential contraction of the stomach in response to sensing the circumferential contraction.
