Abstract

This invention relates generally to an endoscope accessory. This device uses an overtube with an inflatable positioning balloon that can be inflated after placement of the overtube just proximal to the tip of the endoscope or echoendoscope. This balloon creates a temporary blockade of the gastrointestinal tract proximal to the portion that needs to be examined. The other part of the device is a catheter with an occlusion balloon affixed to its free endportion and can be passed through a passageway within the overtube and extended beyond the tip of the endoscope, distal to the part of the gastrointestinal tract that needs to be examined. Inflation of this balloon together with positioning balloon creates a closed space within the body cavity that can be filled with air or water for improving the quality of the examination with regular endoscope of echoendoscope, respectively, while reducing the examination complications.

Claims

1. An endoscope accessory which comprises:

a flexible overtube having a distal endportion and a proximal endportion;

an inflatable positioning balloon affixed to the overtube at the distal endportion thereof;

a cuff affixed to the overtube at the proximal endportion thereof;

an inflation tube for the postioning balloon carried by the overtube;

a fluid conduit carried by the overtube;

a catheter tube carried by the overtube;

said catheter tube defining a passageway for receiving therewithin a catheter; and

a catheter having a midportion thereof situated within the catheter tube and a free, independently positionable distal endportion that terminates in an inflatable occlusion balloon;

said overtube defining a through passageway for receiving therewithin an endoscope or echoendoscope shaft.

2. The endoscope accessory in accordance with claim 1 wherein the overtube is transparent.

3. The endoscope accessory in accordance with claim 1 wherein the overtube forms a fluid tight seal with the endoscope or echoendoscope shaft at the distal endportion of the overtube.

4. The endoscope accessory in accordance with claim 3 wherein said fluid tight seal formed by a washer carried by the overtube.
