A new type of gastric electrical stimulator (GES) was introduced. After the stimulator was implanted in beagle dogs, its stimulating effects and the pathological changes at the implant site were observed to study the safety and efficacy of stimulator as well as the tissue compatibility of the materials used. The results showed that, this type of stimulator was safe and capable of inhibiting food intake of the dogs, and that the materials used had good tissue compatibility.
