Systems and methods for treating gastroesophageal reflux disease
First Claim
1. A system for treating a gastrointestinal condition of a patient, comprising:
- at least one electrode adapted to be implanted such that said electrode is configured to be in electrical communication with a lower esophageal sphincter (LES) of the patient to deliver a pulse stream in accordance with a plurality of stimulation parameters;
a pulse generator in electrical communication with the at least one electrode; and
a non-volatile memory for storing programmatic code which, when executed by a processor, causes the pulse generator to generate the pulse stream in accordance with the plurality of stimulation parameters,wherein the plurality of stimulation parameters comprises at least one of a pulse width having a range of 5 μ
sec to 30 msec, a pulse amplitude having a range of 1 to 30 mAmp, a pulse frequency having a range of 1 to 100 Hz, wherein values for each of the pulse width, pulse amplitude, or pulse frequency are defined such that the gastrointestinal condition is treated, but swallowing of the patient is not hindered, when the pulse stream is delivered to the patient.

Abstract
Systems and methods for treating gastroesophageal reflux disease (GERD) includes minimally invasively implanting a stimulating device in a patient'"'"'s esophagus in the region proximate the lower esophageal sphincter (LES). The patient is provided with a questionnaire related to his disease via an online service. The questionnaire is accessed on a mobile device, such as a cell phone, or on a computer with network access. The data from the sensors and the answers from the questionnaire are analyzed together by a health care provider using the online service. The data and answers are used to program the stimulating device, via the mobile device or computer, to optimize treatment.
