Selected diabetic patients reveal significant glycemic control after bariatric surgical or endoscopic duodenal bypass. This controlling effect appears to occur partly because of an enhanced Glucagon-Like Peptide 1 (GLP1) release from intestinal L-cells. These procedures may also cause complications such as nutritional deficiencies. The present invention provides a stent. The method that places this stent in the ileum to activate the endogenous GLP1 release is a safer alternative to control the diabetes mellitus. However, the less mobile wall of the ileum next to the proximal stent rim can trigger an unwanted telescoping of the intestine, which is known as intussusception. An embodiment of this invention illustrates the characteristics of a stent that can prevent a likely intussusception and consequently be more confidently applied in the ileum to maintain or restore the ileal patency in general or for its anti-hyperglycemic effect in particular.
