Abstract:
This evulsion aid for a fistula catheter has a cylindrical member. The inner diameter of this cylindrical member is larger than the outer diameter of a tube of a fistula catheter, and smaller than the outer diameter of a bumper of the fistula catheter. Moreover, the outer diameter of the cylindrical member is smaller than the fistula. Since the length of the cylindrical member is longer than the fistula, when the cylindrical member is inserted into the fistula, the proximal end of the cylindrical member remains outside the body. When the tube is pulled in the state in which the distal end of the cylindrical member is inserted into the gastric lumen, the bumper is deformed in the direction of contracting diameter by the distal end of the cylindrical member.
Abstract:
A medical multifunctional tube (52) is described for inspecting internal organs of a body. The tube has a substantially free lumen for conveying various elements and also used for conveying liquids and gasses to and/or from organs (5) penetrated by said tube (52). The tube further comprising an imaging sensor (42) incorporated in the anterior face (22; 44) of said tube; at least one conduit of energy (54) to activate said imaging sensor (42) associated with the wall of said tube (52); at least one conducting element (28) for transmitting signals of said imaging sensor (42) to the rear end of said tube, at least one receiver for said signals; and cleaning means triggered by a timer or software for keeping said imaging sensor clear.

Abstract:
PROBLEM TO BE SOLVED: To simply carry out evulsion of a fistula catheter. SOLUTION: The evulsion auxiliary tool 10 of the fistula catheter has a cylindrical member 11. The inner diameter of the cylindrical member 11 is larger than the outer diameter of the tube 2 of the fistula catheter 1 but smaller than the outer diameter of the bumper 3 of the fistula catheter 1. In addition, the outer diameter of the cylindrical member 11 is smaller than a fistula W3. The length of the cylindrical member 11 is longer than the fistula W3. When the cylindrical member 11 is inserted to the fistula W3, the side of a proximal end part 12 is left outside of the body. When the tube 2 is pulled in the state of inserting the distal end 14 of the cylindrical member 11 into the lumen of the gaster, the bumper 3 is deformed in a diameter reduction direction by the distal end 14.
