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.
