A voice prosthesis (1000) for mounting in a fistula between trachea and esophagus is provided. The voice prosthesis (1000) comprises a tubular body (100) having a lumen, a valve disc (201) and a valve seat (202). The valve disc (201) and a valve seat (202) are arranged in the lumen of the tubular body (100), such that the valve disc (201) and the valve seat (202) controls the connection through said lumen by interaction between the valve disc (201) and the valve seat (202). A sealing rim (206) is arranged between said valve disc (201) and said valve seat (202), such that the interaction between said valve disc (201) and said valve seat (202) is obtained via said rim (206). A method for manufacturing a voice prosthesis is also provided. |
