Urethral autostatic endoprosthesis

摘要

The urethral autostatic endoprosthesis (1) can be self connecting to the prostatic urethra for trans-urethrally draining vesical urines and comprises a hollow, tubular structure (2) made of biocompatible, non-deformable material. The structure has longitudinally extending openings (2') on the lateral surface. A pair of proximal tongues (3) made of biocompatible, flexible, non-traumatic material is formed on one end of the tubular structure. The tongues are flaired prolongations of the tubular end and are diametrically opposite one another. Similar distal tongues (3') are formed at the other end of the tubular structure, but are smaller than the proximal tongues.
