Abstract
The present invention is directed to a novel device and method for providing a disposable endotracheal intubation device for use with an auxiliary passageway serving as a guide for the placement of an orogastic or other enterally directed device in a patient. The present invention pertains to a combination intubation device comprising an endotracheal tube and a catheter proximate the endotracheal tube to guide the path of an enteral tube. In a preferred embodiment, the endotracheal tube is capable of defining an arcuate path in a first geometric plane between its proximal end and its distal end to facilitate introduction of the tube into the trachea of a patient. In a preferred embodiment, the catheter employs a fenestration to facilitate removal of the intubation device from the patient without removal of any enteral device previously directed therethrough into the patient.
