Esophageal introducer

摘要

An esophageal introducer is provided which facilitates the passage of medical probes into the esophagus or gastric cavity. It consists of an introduced tube 12 made of collapsible elastomeric material 21 with a flexible laminated steel at the bottom 20. The proximal opening is attached to a bite block 10. The distal end continues with an extension of the laminated steel 20a that tapers to a tip with a 45 degree bend 16. This extension is covered with elastomeric material 21a that overlaps the distal tip creating a flat soft end 19. Prior to insertion the introducer body is bended 20-30 degrees 17, the tip is advanced till it makes contact with the posterior pharyngeal wall FIG. 3a. ;Further pressure will advance the tip effortlessly, sliding on the posterior esophageal wall that is an anatomic continuation of the posterior pharyngeal wall. FIG. 3b, 3c.

主权项

1. An article of medical use being an esophageal introducer to facilitate the passage of medical instruments form the mouth into the esophagus that comprises:
(a) an elongated, fully collapsible within the anatomical boundaries of use introducer tube made with means for structural consistency along a bottom of said introducer tube, said introducer tube having a proximal end, a distal end, and a lumen extending between; said introducer tube having a predetermined internal diameter large enough to allow medical instruments to pass unobstructed through a length thereof, said length enough to traverse the distance from the mouth incisors line to the esophageal opening; (b) a bite block attached to the proximal end of said fully collapsible introducer tube; and (c) a distal extension of the introducer tube having a flat, tapered shape of a predetermined length that is a continuation of said bottom of the introducer tube with means for structural consistency.
