Abstract
A device and method that reduces impingement upon fragile airway structures and improves the performance and safety associated with endotracheal devices and related intubation procedures. The endotracheal device includes a lumen such that one end of the lumen includes an anterior beak that includes a distal tip of the anterior beak and a posterior beak having a distal tip of the posterior beak.
Claims24
An endotracheal device, said device comprising:
- a lumen having an inner diameter and central axis running longitudinally along the length of the lumen;
- said lumen having a proximal portion and a distal portion opposite said proximal portion;
- said distal portion having an anterior beak that includes a distal tip of the anterior beak and a posterior beak having a distal tip of the posterior beak;
- said anterior beak having an exterior wall whereby said exterior wall has a configuration that is generally curved inward having a rounded shape;
- said posterior beak having an exterior wall whereby said exterior wall has a configuration that is generally curved inward having a rounded shape;
- said distal tip of said anterior beak is longitudinally spaced at a predetermined distance distally from said distal tip of said posterior beak so as to define a longitudinal beak offset;
- said distal tip of said anterior beak and said distal tip of said posterior beak are configured laterally inward toward one another and spaced at a predetermined distance laterally from each other in a relaxed state so as to define a lateral-inward beak offset;
- and
- wherein said lateral-inward beak offset is in the range of about 50 percent to 90 percent of said inner diameter of said lumen.

- in the range of 45 percent to 50 percent of said inner diameter of said lumen;
- in the range of 50 percent to 55 percent of said inner diameter of said lumen;
- in the range of 55 percent to 60 percent of said inner diameter of said lumen;
- in the range of 60 percent to 65 percent of said inner diameter of said lumen;
- in the range of 65 percent to 70 percent of said inner diameter of said lumen;
- in the range of 70 percent to 75 percent of said inner diameter of said lumen;
- in the range of 75 percent to 80 percent of said inner diameter of said lumen;
- in the range of 80 percent to 85 percent of said inner diameter of said lumen;
- in the range of 85 percent to 90 percent of said inner diameter of said lumen;
- in the range of 90 percent to 95 percent of said inner diameter of said lumen;
- in the range of 95 percent to 100 percent of said inner diameter of said lumen;
- in the range of about 30 percent to about 120 percent of said inner diameter of said lumen;
- or
- in the range of about 30 percent to 200 percent of said inner diameter of said lumen.
