<unk>  is an endoscopic suturing system designed to treat patients who have had previous Roux-en-Y gastric bypass surgery. Following this surgery, the stomach pouch and stomach outlet (stoma) becomes enlarged in some patients. The<unk>  device can be used to restrict the size of the stoma without exposing the patient to further surgical risk. Although initial post-procedure weight loss is evident in some trials, there is doubt as to whether such results are sustained over the long term. The<unk>  device was patented by EndoGastric Solutions.
