Novel Devices for Endoscopic Suturing: Past, Present, and Future.

Endoscopic suturing has been described in many applications, including the approximation of tissue defects, anchoring stents, hemostasis, and primary and secondary bariatric interventions. Primary endobariatric procedures use endoscopic suturing for gastric remodeling with the intention of weight loss. Currently, the only commercially available device in the United States is the OverStitch endoscopic suturing system (Apollo Endosurgery). We describe devices of potential that are currently in design and/or trials as devices for weight loss by gastric remodeling, including USGI incisionless operating platform used for the primary obesity surgery endoluminal 2.0 procedure, Endomina used for the Endomina endoscopic sleeve gastroplasty, and EndoZip.
