An incisionless, implantable antiobesity medical device from EndoSphere has received the CE Mark, which signifies European regulatory approval. EndoSphere’s device, called the Satisphere, works by slowing the passage of food through the duodenum, the upper part of the smaller intestine that breaks down food. Because food is in contact with the duodenum for a longer time, the device essentially fools the body into thinking that it’s consumed more food than it actually has. The company says the device helps patients lose weight without requiring surgery or medication.
