Direct percutaneous endoscopic jejunostomy method and apparatus

摘要

A method and apparatus of administering a percutaneous access catheter directly into the jejunum of a patient. The apparatus including a wire having a proximal and distal end. The distal end of the wire includes a probe and the proximal end includes a bend. The needle is provided within a sheath which movably surrounds the wire such that the probe is emergent from the sheath. The method including the steps of administering the sheath and wire of the present invention such that the wire enters the mouth of the patient, passes through the esophagus and extends into the jejunum of the patient, moving the wire to expose the probe beyond the sheath, piercing the wire through the jejunal wall and through the abdominal wall. The method further including attaching a percutaneous access tube to the proximal end of the wire and pulling the wire from its distal end, thereby pulling the tube such that it extends from inside the jejunum to outside the patient's abdominal wall.
