Abstract:
An endoscopic guide for catheters and or endoscopes, comprising a tubular guiding element, an anchoring head, said anchoring head being provided at least with a container for accommodating a magnetic agent, the container being connected to said guiding element's longitudinal cavity, a magnetic agent which can move in said a longitudinal cavity in order to fill/empty the container and a manually maneuverable magnetic field source.

Claim (Index 1):
A method for introducing a colono scope into a colon of a patient, the method comprising:\n providing a colonoscope comprising:\n a distal end configured to be introduced into the colon, and \n a proximal end connected to a maneuver and control manipulator; \n providing an endoscopy system, wherein the endoscopy system comprises:\n an endoscopic guide comprising:\n a proximal end, \n a distal end, \n a tubular guiding element comprising:\n a body having a diameter between 2 mm and 3.5 mm and comprising a single lumen having an inner diameter between 1 mm and 3 mm, \n a longitudinal cavity, \n \n an anchoring head comprising an endoscopic balloon configured to accommodate a magnetic or ferromagnetic agent, the endoscopic balloon expandable and retractable between a retracted condition, in which the endoscopic balloon is adherent to the body of the tubular guiding element, to an expanded condition, in which the endoscopic balloon protrudes externally from the body of the tubular guiding element, the endoscopic balloon being in communication with the longitudinal cavity of the tubular guiding element, the endoscopic balloon having an expanded volume between 20 mL and 40 mL, and \n a magnetic or ferromagnetic agent movable in the longitudinal cavity of the tubular guiding element and configured to fill and empty the endoscopic balloon, the magnetic or ferromagnetic agent comprising a liquid and a plurality of magnetizable bodies in dispersion in the liquid, wherein the magnetic or ferromagnetic agent comprises an aqueous suspension of magnetite or maghemite or a ferrofluid, and wherein the magnetic or ferromagnetic agent comprises a suspension of 30% to 70% vol/vol of iron oxides in water, the expanded volume of the expandable balloon corresponding to a volume of the magnetic or ferromagnetic agent contained therein; and \n \n a magnetic field source comprising a permanent magnet, the magnetic field source configured to generate a magnetic field equivalent to that generated by a permanent discoid magnet with N45 magnetization having a diameter between 50 mm and 80 mm and a thickness between 30 mm and 60 mm to exert a retaining force on the magnetic or ferromagnetic agent contained in the endoscopic balloon, with respect to a transverse pulling direction, greater than 5 Newton at a distance between 2 cm and 10 cm when a pulling force of at least 5 Newton is applied on the proximal end of the endoscopic guide; \n introducing the distal end of the colonoscope through an anus of the patient until a blockage point is reached; advancing the endoscopic guide through the colonoscope and a distance between 4 cm and 10 cm beyond the distal end of the colonoscope by pushing the proximal end of the endoscopic guide; introducing between 20 mL and 40 mL of the magnetic or ferromagnetic agent into the endoscopic balloon to expand the endoscopic balloon to the expanded volume; applying the magnetic field 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, with respect to a transverse pulling direction, greater than 5 Newton; putting the endoscopic guide in traction by applying a pulling force of at least 5 Newton on the proximal end of the endoscopic guide to keep the endoscopic guide tensioned and to reduce curvature of loops of the colon; and advancing the colonoscope over the endoscopic guide to the anchoring point of the endoscopic balloon.
