Eska® Herrmann
Clinical application
The Eska® Herrmann prosthesis was developed for insertion in a surgically created, so called "tracheal chimney". It can also be introduced without a tracheal chimney and is available in various bends. The comparatively small inner diameter creates a higher airflow resistance. The bill valve is stable against underpressure related valve openings.
