Abstract
The tracheal prosthesis is intended to replace damaged, diseased or missing tracheal and/or bronchial segments. The tracheal prosthesis comprises a plastic shaft which is embraced by hoops. The hoops 9 stabilize the thin film-like material wall. As in the case of the human trachea, the hoops leave an area of the plastic shaft uncovered so that a particularly resilient circumferential surface is obtained between the hoops, resembling the membranaceous part of the human trachea. The ends of the tracheal prosthesis are reinforced by spring elements. These spring elements ensure that the tracheal prosthesis is retained safely in the natural tracheal and/or bronchial stumps. The inner surface of the tracheal prosthesis is hydrophilized.
