Abstract:
A voice prosthesis to be mounted in a fistula between trachea and esophagus includes an outer cannula and a removable, disposable inner cannula. Both outer and inner cannula are tubular shaped with the inner cannula fitting inside the outer cannula. The inner cannula element with a through passage and a valve mechanism controlling the connection through said passage. A coupling mechanism is provided on the proximal end of the inner cannula to provide easy, releasable attachment of the inner cannula to the outer cannula. The inner cannula is inexpensively constructed and is dimensionally compatible with the outer cannula.

Claim (Index 1):
A voice prosthesis for insertion into a fistula in a tracheoesophageal wall of a patient, comprising:\n an outer cannula comprising a hollow, annular, flexible body configured to be inserted into a fistula and to maintain the fistula open, the outer cannula further comprising a first retention flange at a tracheal end of the body, and a second retention flange at an esophageal end of the body, the body having a through passage defined therein between the tracheal end and the esophageal end; and a removable inner cannula comprising a hollow, annular, rigid body to be inserted into the through passage of the outer cannula, the inner cannula further comprising a retention flange at a tracheal end of the inner cannula when positioned into the passageway, the rigid body having a through passageway defined therein, the rigid body open at both the tracheal end of the inner cannula and an esophageal end of the inner cannula, the rigid body.
