The Transneuronix Implantable Gastric Stimulation system is like a pacemaker for the belly. Implanted into the abdomen, it zaps nerves in the stomach to make you think you're full. From the Transueronix product page:
The lead is typically implanted in a minimally invasive laparoscopic procedure. The distal end is contiguous with a surgical needle that is used to insert the lead through the musculature of the stomach wall. The needle is then cut from the lead and removed from the abdominal cavity.Link to Transeuronix, Link to BBC News article
The programmer consists of a computer connected to a small programming wand. It is used to check and, if necessary, change electrical values of the IGS before and after implantation. Communication is accomplished noninvasively via radio frequency signals.
