Gastric constriction device with selectable electrode combinations
First Claim
1. An implantable medical device comprising:
- a gastric constriction device positioned to constrict a portion of a gastrointestinal tract of a patient;
a plurality of electrodes carried by the gastric constriction device;
a stimulation generator that generates electrical stimulation energy; and
a switch device that selects one or more of the electrodes and couples the stimulation energy to the selected electrodes to deliver the stimulation energy to the patient.

Abstract
This disclosure describes an implantable medical device that delivers electrical stimulation to a patient in combination with limiting ingestion of food by the patient to treat obesity. The device includes a gastric constriction device, such as a hydraulic or electro-mechanical gastric band, having a plurality of electrodes integrally formed thereon. One or more of the electrodes, i.e., an electrode combination, are selected to deliver electrical stimulation energy, e.g., in the form of stimulation pulses, to the patient. The electrode combination may deliver pulses in accordance with various modes, e.g., continuously, in a series of bursts, or a combination of both. When more than one electrode combination is selected, each electrode combination may deliver pulses in accordance with a different set of stimulation parameters. The electrode combinations may deliver pulses at the same time or on a time-interleaved basis.
