Abstract
A voice prosthesis comprising a outer cannula and an inner cannula wherein the outer cannula is generally in the shape of a spool and comprises two flanges connected by a hollow annular stem therebetween, and the inner cannula comprises a proximal flange and a stem configured to fit within a passageway of the stem of the outer cannula. The outer cannula comprises a retaining slot on its outer proximal edge which can be used to rotationally secure an obround inner cannula proximal flange. The inner cannula may also comprise windows for use with retaining nubs disposed on the interior of the outer cannula passageway and an insertion tool having a moveable protrusions.
Claims25
A voice prosthesis device, comprising:
- an inner cannula comprising a distal end and a proximal flange connected by a annular second stem, the annular second stem defining a passageway therethrough;
- and
- an outer cannula comprising a distal flange and a proximal flange connected by an annular first stem, the annular first stem defining a passageway therethough;
- wherein the inner cannula comprises a valve;
- and
