European Novel Motorized Spiral Endoscopy Trial

The subject Novel Motorized Spiral Enteroscope (NMSE) represents a new technology which offers all of the advantageous options of spiral enteroscopy with a faster and less invasive approach. The system is similar to other currently marketed endoscopes in that it incorporates a flexible insertion tube, light source, digital imaging, and channels for passing accessories for sample collection or therapeutic interventions. The NMSE system is unique in that it incorporates a user-controlled motor contained in the endoscope’s handle to rotate a spiral cuff located on the endoscope’s insertion tube. Rotation of this cuff, which has soft spiral-shaped "fins", pleats the small bowel on to the endoscope’s insertion tube, thereby allowing rapid and atraumatic access deep into the small bowel. The system also includes a display monitor, a motor control unit, device to display measured motor current and signal torque, and a set of foot pedals. Motorization of the Spiral Enteroscope and limitation of rotation to a short cuff instead of a long overtube promise to accelerate the procedure, to facilitate insertion and to improve maneuvering the instrument in comparison to conventional spiral enteroscopy
