A voice prosthesis device for insertion into a tracheoesophageal opening of a wearer and a method of making it. The device comprises a barrel providing a first passageway therethrough, a tracheal flange adjacent a tracheal end of the barrel and an esophageal flange adjacent an esophageal end of the barrel. The tracheal flange and esophageal flange aid in retaining the voice prosthesis device in the tracheoesophageal opening. The first passageway may include a first stop extending inwardly from a sidewall of the first passageway between the tracheal and esophageal ends and a plurality of second stops extending inwardly from the sidewall of the first passageway between the first stop and the esophageal end of the first passageway. A valve mechanism between the first stop and the second stops permits flow through the first passageway from the tracheal end and impedes flow through the first passageway from the esophageal end. At least one second passageway may be provided on the valve mechanism. The at least one second passageway intersects a sidewall of the first passageway when the valve mechanism is inserted into the first passageway. The second passageway contains a material to fix the valve mechanism in the first passageway.
