The FDA has approved an abdominal implant (Enterra, Medtronic Corp, Fridly, Minn) for treatment of chronic, intractable (drug-refractory) nausea and vomiting secondary to gastroparesis of diabetic or idiopathic etiology. The device consists of intramuscular stomach leads and an implantable pulse generator (IPG). The stomach leads are implanted via laparoscopy on the greater curvature of the stomach and are connected to the IPG, which is implanted in a subcutaneous pocket created in the abdomen.
