Patent Images
1. A method comprising:
- generating electrical stimulation including a first electrical stimulation pulse and a plurality of pulse bursts, wherein the first electrical stimulation pulse has a duration greater than approximately 100 milliseconds, each of the pulse bursts having a duration of greater than approximately 100 milliseconds, wherein each of the pulse bursts includes a plurality of second pulses, each of the second pulses having a pulse width of approximately 2 milliseconds to approximately 20 milliseconds; and
applying the electrical stimulation to a gastrointestinal tract of a patient to cause gastric distention, wherein applying the electrical stimulation includes application of the electrical stimulation pulse followed by at least one of the plurality of pulse bursts.

Abstract
In some examples, electrical stimulation therapy is delivered to support obesity management. The electrical stimulation therapy is configured to cause at least partial gastric distention. Gastric distention tends to induce a sensation of fullness and thereby discourages excessive food intake by the patient. The electrical stimulation therapy may be delivered to the gastrointestinal tract of the patient by electrodes deployed by one or more implantable leads coupled to an electrical stimulator. The electrical stimulator delivers stimulation pulses having a pulse width in a range found to be effective in causing gastric distention.
