1. A device for facilitating intubation of a distal end of a shaft of an endoscope within the upper gastrointestinal tract, comprising:

  • a hood for shielding and carrying the distal end of the endoscope, the hood having a pocket for receiving the distal end of the endoscope, the pocket being defined by a plurality of deformable leaves, the pocket having inner dimensions generally corresponding to the outer dimensions of the distal end of the endoscope; and

    ,an elongated hood control means joined to the hood for external manipulation of the hood, the length of the control means being coextensive with at least the length of the shaft so that a proximal end of the control means may protrude out of a patient'"'"'s mouth;

    such that an endoscopist may insert the hood on the shaft by seating the distal end within the pocket, upon intubating the shaft and achieving selected positioning of the shaft within the esophagus the endoscopist draws on the proximal end of the control means while maintaining the shaft in a stationary position to cause movement of the hood along the shaft in an orad direction, such orad directional movement of the hood causes the leaves to deform and retract thereby opening the pocket and exposing the distal end, continued drawing on the control means in the orad direction causes a complete withdrawal of the hood from the distal end of the shaft.
