Devices, systems and methods are provided for electrical stimulation of a body organ, particularly within the gastrointestinal tract. In preferred em bodiments, the stomach is the organ within the gastrointestinal tract which is targeted for such stimulation. A guide wire (100) or other delivery devic e is positioned within the body so as to transect the stomach wall (W) Devic es and systems are then advanced over the guide wire for attachment to the s tomach wall. The guide wire may be placed by endoscopic, open, laparoscopic or a modified percutaneous approach. In a modified percutaneous approach, th e stomach is accessed without the use of general anesthesia by advancing a n eedle (120) through the abdomen, transecting the stomach wall with the needl e and advancing the guide wire through the needle. In some embodiments, part icularly for use in obese patients, the modified percutaneous approach inclu des advancing a trocar (130) through the tissue of the patient toward the ou ter surface of the organ and advancing the needle through the trocar prior t o transecting the wall with the needle.
