Dual-lumen tracheal tube with shaped lumen divider

摘要

Various embodiments of a tracheal tube having a shaped divider disposed therein for separation of a tracheal tube into multiple ventilation lumens are provided. In some embodiments, the divider divides a tracheal ventilation lumen from a bronchial ventilation lumen. In some embodiments, the shaped divider provides an irregular inner diameter that allows a relatively bulky device to be inserted into one or both lumens.

主权项

1. A tracheal tube, comprising:
a side wall; a first ventilation lumen having a first distal end and a first proximal end; a second ventilation lumen adjacent to the first lumen, the second ventilation lumen having a second distal end and a second proximal end; and a flexible divider coupled to the side wall, the flexible divider dividing the first ventilation lumen from the second ventilation lumen and forming a portion of an exterior wall of the second ventilation lumen at a location distal to the first distal end of the first ventilation lumen and wherein the flexible divider extends to the second distal end, wherein the first ventilation lumen and the second ventilation lumen have substantially equal cross-sectional areas, and wherein the flexible divider comprises alternating inelastic thick portions and elastomeric thin portions, and wherein the flexible divider has rigid and non-planar side surfaces to create at least one enlarged region for passage of a medical device through the enlarged region.
