Abstract
A multi-layered transtracheal catheter. The transtracheal catheter has a multi-layer or double wall construction formed of two materials. One material is resistant to kinking. The other material is resistant to mucous buildup. Together, they form a catheter that can remain within the trachea for an extended period of time without needing to be removed for cleaning. The distal end of the catheter is deflected from the remainder of the catheter so that when the catheter is inside the trachea and held against the wall of the trachea, the distal end of the catheter is deflected from the wall so that the distal end is not in contact with the wall of the trachea. The result is reduced irritation to the trachea wall, reduced occlusion of the distal end by mucous buildup, and a more directed and efficient spray of material from the catheter into the right and left main skin bronchi of the lungs.
