1. A multifunctional accessory channel device comprising a tube, a proximal adapter for attachment of the tube to a control section of an endoscope, and a distal adapter for attachment of the tube at or near a distal tip of an endoscope, wherein:
the tube comprises a tube body, a proximal end, a proximal opening, a distal end, and a distal opening;
the tube defines a channel internal to the tube extending from the proximal opening to the distal opening;
the tube has an outer surface and an inner surface;
the tube has a slit that extends continuously along the tube from a proximal portion of the tube to a distal portion of the tube and continuously through the tube from the outer surface of the tube to the inner surface of the tube;
the distal portion of the tube to which the slit extends is a portion of the tube adjacent to the distal end of the tube;
the slit has a proximal end and a distal end;
the slit has a length that is the distance from the proximal end of the slit to the distal end of the slit;
the slit has a depth that is the distance from the outer surface of the tube to the inner surface of the tube;
the slit is reversibly locally openable along the length and the depth of the slit by translation of a portion of an accessory through and along the slit but is otherwise fully closed;
the proximal opening of the tube is located at the proximal end of the tube;
the distal end of the tube is shaped as a notch that has opposing notch sides that extend distally from the distal end of the slit along the distal end of the tube, diverge distally, and form the distal opening of the tube;
the proximal adapter comprises a proximal adapter body, a first component to attach the tube to the proximal adapter body at or near the proximal end of the tube, and a second component to attach the proximal adapter body to a control section of an endoscope;
the distal adapter for attachment of the tube at or near a distal tip of an endoscope comprises a first surface for attachment of the tube to the distal adapter at or near the distal end of the tube, a second surface for attachment of the distal adapter to the endoscope at or near the distal tip of the endoscope, and a distal adapter body therebetween; and
the tube is attached to the first surface of the distal adapter at or near the distal end of the tube.
