Abstract
An inflatable balloon cuff associated with a tracheal tube may be adapted to filter microbial secretions and reduce their passage into the lungs. A cuff as provided may include a cross-linked polymeric structure that may serve to exclude certain secretions on the basis of size. The polymeric structure may be incorporated onto all or part of the surface of the inflatable balloon cuff.
