ENDOSCOPIC GUIDE, IN PARTICULAR FOR COLONOSCOPY, AND SYSTEM FOR ENDOSCOPY COMPRISING SUCH A GUIDE

摘要

Methods and devices for introducing a colonoscope. An head of an endoscopic guide includes a balloon configured to accommodate a magnetic or ferromagnetic agent. A magnetic field source is configured to generate a magnetic field to exert a retaining force on the magnetic or ferromagnetic agent contained in the endoscopic balloon. The magnetic field is applied using the magnetic field source externally at an area of an abdomen of the patient in which the expanded endoscopic balloon with the magnetic or ferromagnetic agent is present to attract the endoscopic balloon against an anchoring point on a wall of the colon with a retaining force on the magnetic or ferromagnetic agent. The endoscopic guide is put in traction by applying a pulling force on the proximal end of the endoscopic guide to keep the endoscopic guide tensioned and to reduce curvature of loops of the colon.
