摘要：
Disclosed is a system for treating a patient with gastroesophageal reflux disease. The system comprises: at least one electrode configured to be positioned in electrical communication with the patient&rsquos lower oesophageal sphincter (LOS) a waveform generator operably coupled to said at least one electrode a controller configured to electrically stimulate the LOS to increase the pressure or function of the LOS from a first level to a second level and an accelerometer coupled to the controller for sensing posture data of the patient. The increase in LOS pressure or function above the first level occurs during stimulation and continues after stimulation ceases. The controller controls the waveform generator to repeatedly: a) generate and apply an electrical pulse train to the LOS through the at least one electrode for a stimulation period and b) terminate the electrical pulse train for a rest period. The controller is configured to control the waveform generator to adjust parameters of the electrical pulse train applied to the LOS based on an analysis of the posture data from the accelerometer. The controller is configured to switch between a first stimulation mode to a second stimulation mode when the posture data crosses a predetermined threshold value.
