EndoBarrier® is an endoscopically delivered medical device intended to help restore healthy blood sugar levels and reduce weight.

EndoBarrier is an investigational medical device for people living with uncontrolled type 2 diabetes and obesity that is sought to bridge the gap between partially effective medications, insulin injections, and irreversible surgery.

How it Works

EndoBarrier is a thin, flexible 60 cm sleeve that is endoscopically implanted within the small intestine by a trained physician. The implant secures itself with an anchoring mechanism at the upper portion of the small intestine. Placement is performed as an outpatient procedure that does not require incisions.

Once in place, EndoBarrier conforms to the shape and movement of the intestine and may begin to work immediately by creating a physical barrier between receptors in the intestinal wall and food that has been shown to directly affect key hormone levels.


What it Does

Non-US Clinical studies have shown that EndoBarrier creates changes in gut hormones that mimic mechanisms similar to Roux-en-Y gastric bypass (RYGB)1 and reduces cardiovascular risks2 and liver fibrosis through positive clinical outcomes.

Clinical data suggests EndoBarrier improves insulin resistance and glycemic control and reduces weight in patients with type 2 diabetes and obesity.1

EndoBarrier has been shown to:

  • Lower blood sugar levels (HbA1c)1, 2
  • Increase weight loss and lower BMI1,2
    • Reduce cardiovascular risk2

    The most commonly reported complications of EndoBarrier are gastrointestinal in nature. They include nausea, vomiting, and upper abdominal pain of mild to moderate severity and are mostly prevalent in the early days and weeks following EndoBarrier placement. Uncommon risks include liver abscess, device-related bleeding, device migration, pancreatitis, or other infections, any of which may result in endoscopic or surgical removal of the device. As with all endoscopic and/or implant procedures, serious injury or death can occur.


    Treatment with EndoBarrier may last up to 12 months but should not exceed 12 months.

    Removal of EndoBarrier is conducted through an endoscopic outpatient procedure under general anesthesia.
