The Elastic Traction System is indicated for adult only for use in flexible Endoscopy to provide retraction to assist in tissue resection, exposure, and removal of tissue within the stomach and colon.

The proposed device, Elastic Traction System, consists of 2 components, an Elastic Traction Device, and a clipping device (Fig. 1). Two components are single use device. The Elastic Traction Device is a single use tissue traction device. It is consisting of clip assembly, silicone band and delivery system. The silicone band is consisting of three rings. Ring A is preloaded with the clip. The Clipping Device is a single use device, and its purpose is to use it as a second clip. The second clip is used to engage the silicone band of the previously anchored clip of Elastic Traction Device.

ProdiGI Traction Wire: The Medtronic ProdiGI Traction Wire is indicated to grasp tissue within the esophagus, stomach, and colon of adults during an Endoscopic Submucosal Dissection (ESD) procedure. ProdiGI Traction Magnet: The Medtronic ProdiGI Traction Magnet is indicated to grasp tissue within the stomach and colon of adults during an Endoscopic Submucosal Dissection (ESD) procedure.

The ProdiGI Traction System includes the Traction Wire and Traction Magnet devices. The Traction Wire and Traction Magnet are not intended to be used together. Both devices are used in adults only and are used to provide improved visualization of the submucosal space during an endoscopic submucosal dissection (ESD) procedure. ProdiGI Traction Wire Device: The Traction Wire consists of two graspers: a primary tissue grasper with traction wire attached (ERD-TW20 and ERD-TW35), and a secondary tissue grasper (ERD-TWSG) without a wire. The secondary tissue grasper is used to secure the distal end of the traction wire. The traction wire is a nitinol shape-memory loop (2.0 cm or 3.5 cm in length) that provides tension to the attached tissue after deployment. The nitinol wire is attached to the grasper with a stainless-steel crimp. ProdiGI Traction Magnet Device: The traction magnet (ERD-TMST and ERD-TMLG) consists of two identical tissue graspers with a permanent neodymium magnet attached to the grasper via a suture. The sutured magnet provides tension to the attached tissue after deployment.
