Claim Text:
1. A method for positioning a linear array of electrodes mounted on a distal end section of an elongated flexible member in a patient's respiratory airways at the level of the patient's diaphragm, comprising: inserting through the patient's respiratory airways a length of the elongated flexible member pre-determined to position the linear array of electrodes at the level of the patient's diaphragm; detecting through the electrodes of the linear array signals representative of an electrical activity of the patient's diaphragm (EAdi); detecting lower esophageal sphincter activity in the EAdi signals; and detecting adequate positioning of the linear array of electrodes in the patient's respiratory airways at the level of the patient's diaphragm as indicated by the detected lower esophageal sphincter activity.
