title: [The further development of a human, alloplastic tracheal prosthesis].
abstract: The present paper discusses the design, construction and characterization of human alloplastic tracheal prostheses. Two different types of construction, the spiral and the clasp prosthesis, have been developed. The prostheses are composite constructions comprising a silicone tube and a polyethylene reinforcement connected together by means of a biocompatible adhesive. The results of various mechanical examinations (stress-strain behavior, torsional strength, compressibility, bending stiffness, fatigue testing) show that some of the 14 prostheses investigated approach the human trachea in terms of mechanical properties, and may be considered suitable. Suggestions for further improvements are made.
