Abstract

An overtube device is disclosed as comprising, in at least one embodiment, a body having a proximal opening and an opposing distal opening in fluid communication with one another via a primary lumen formed within the body, the primary lumen configured for selective receipt and passage therethrough of an endoscope, and a secondary lumen formed within the body so as to intersect and be in fluid communication with the primary lumen and, thus, the distal opening. The secondary lumen is configured for selective engagement with a suction system and defines a suction port. With the distal end of the overtube device attached to the overtube and the suction system engaged with the suction port of the overtube device, suction applied via the suction system through the suction port is, in turn, capable of being applied to the overtube.

Dependent claims

An overtube attachment device configured for selective engagement with each of an overtube and a suction system, the overtube attachment device further configured for selective receipt therethrough of an endoscope, the overtube attachment device comprising:

a body having a proximal opening formed at a proximal end and a distal opening formed at a distal end, the distal opening configured for removable engagement with the overtube;
a primary lumen formed through the body and interconnecting the proximal opening with the distal opening, the primary lumen sized and shaped for allowing the endoscope to be slidably moved therethrough while also being sized and shaped for allowing an esophageal food impaction to be retrieved from an esophagus of a patient and slidably moved through the primary lumen, the primary lumen having an inside diameter of between 14 mm and 40 mm;
and
a secondary lumen formed in the body so as to intersect and be in fluid communication with the primary lumen through a suction port provided by the secondary lumen and configured for removable engagement with the suction system, the secondary lumen being sized and shaped for allowing the food impaction to be retrieved from the patient's esophagus and slidably moved through the secondary lumen via the suction port;
whereby, in an operational configuration, the overtube attachment device allows the endoscope to slidably move through each of the proximal opening and the overtube via the primary lumen and, upon the endoscope being withdrawn to a location behind the secondary lumen, further allows the suction system to retrieve the food impaction from the patient's esophagus via the overtube and divert the food impaction through the secondary lumen and out the suction port, thereby subsequently leaving the primary lumen unobstructed by the food impaction.

and
a suction system comprising:
a vacuum pump in fluid communication with the suction port of the secondary lumen;
and
a separator positioned inline between the vacuum pump and the suction port, the separator configured for retaining the food impaction;
whereby, in an operational configuration, the overtube attachment device allows the endoscope to slidably move through each of the proximal opening and the overtube via the primary lumen and, upon the endoscope being withdrawn to a location behind the secondary lumen, the suction system is able to retrieve the food impaction from the patient's esophagus via the overtube and divert the food impaction through the secondary lumen, out the suction port and into the separator, thereby subsequently leaving the primary lumen unobstructed by the food impaction.
