Abstract: Systems and methods for gastrointestinal electrical stimulation to treat abnormalities in gastrointestinal motility are provided. In some embodiments, a system for relieving ileus includes an intraluminal catheter comprising: a catheter body having a proximal tip and a distal tip and a duodenal portion proximal to the distal tip of the catheter; and at least one electrode pair disposed along the duodenal portion of the intraluminal catheter, the at least one electrode pair being configured to detect a sensing information indicative of myoelectric activity of a patient and to provide stimulation energy; a sensing system in communication with the at least one electrode pair to receive the sensing information; and an energy delivery system in communication with the at least one electrode pair and the sensing system, the electrical energy delivery system being configured to delivery energy to the patient through the at least one second electrode pair based on the sensing information from the sensing system.
