ABSTRACT:
A device for facilitating insertion of an endoscope into the esophagus which includes an elongated tube composed of a flexible elastomer, the tube having a substantially uniform outer diameter along most of its length and a solid tapered tip end, the tip end being joined to the remainder of the tube by means of a hollow tapered neck portion. The tube is provided with an opening behind the neck of generally elongated configuration. The geometry of the opening and the flexibility of the tube are such that when the distal end of an endoscope is inserted into the aperture, the distal end is slightly bent and is received in wedged engagement within the tapered neck portion, and a portion immediately behind the distal end of the endoscope is resiliently supported by a portion of the periphery of the opening formed in the tube.
