The manufacturer’s website describes it like this:
The Enterra® gastric neurostimulation system uses mild electrical pulses to stimulate the antrum portion of the stomach muscle wall. This gastric electrical stimulation may reduce the symptoms of nausea and the number of vomiting episodes related to gastroparesis.1
The Enterra gastric neurostimulator operates on a sealed battery and electronic circuitry to provide controlled electrical pulse stimulation, through the implanted lead system. The neurostimulator can be turned off or removed if there is no longer a benefit.
A wide range of noninvasively programmable parameters and stimulation modes are available. The neurostimulator provides current parameter information, via telemetry, when used with the clinician programmer.
Gastric electrical stimulation may control symptoms, but is not a cure for gastroparesis. Often, a combination of therapies is needed to adequately control symptoms. Rate of improvement varies from person to person.

“Abell, T” is the physician who placed the temporary pacemaker in Anne, in Mississippi.
It looks like this:
It is a little less than 2.5 inches in height and width. It will be placed under her skin on her abdomen. From there two wires will be attached to her stomach muscle wall.
The pacemaker is programmed by a remote control that looks like this:
The procedure is usually done on an out-patient basis and she should come home that day.
There is no guarantee that the pacemaker will work, but the success rate is pretty impressive. It also will not “cure” the underlying cause(s) of her cyclic vomiting, but it should significantly reduce the length an severity of episodes. It is even possible that it might prevent the episodes from manifesting themselves through vomiting altogether.
Please keep her and her physicians in prayer.
