British scientists have developed an implanted sleeve that looks like a giant sausage skin, which they claim can cure diabetes.

A team, led by Dr. John Mason of the Trafford Healthcare National Health Service Trust U.K., says that the two-feet-long device can reverse diabetes within weeks - in fact, it acts as an incision-less alternative to a weight loss surgery known as duodenal switch.

The duodenum is the name for the first 10 to 12 inches of the small intestine, which attaches to the stomach.

The new device, called the EndoBarrier, is designed to have the same effects as the surgery but far safer. It is a plastic sleeve that lines the duodenum, meaning food can only be absorbed lower down the intestine.

The procedure is performed under anaesthetic in less than an hour. The sleeve - made from a thin plastic - is inserted via the mouth and passed into the digestive tract using a thin tube, the Daily Mail reported.

Once in place, a sprung titanium anchor prevents it slipping out. It is removed after a year. During trials researchers found that in obese patients who also suffered diabetes, the disease went into remission.

The discovery has led to clinical trials at three British hospitals, which found the implant also lowers cholesterol levels and blood pressure.
