McCallum and three researchers moved to El Paso from Kansas University, where he had a similar program. At Kansas, he and his team implanted about 275 gastric stimulators.
Dr. Irene Sarosiek, who also came from Kansas with McCallum, is the director of the neurostimulation program.

"Quality of life is one of my biggest," he said.
McCallum said about five patients are waiting for the procedure.
"Surgery is an invasive step, so we first want to make sure they exhausted all other options, like medicine and all the tricks of the trade that we have learned," he said.
