VOICE PROSTHESIS BRUSH

摘要

A brush (10) for a voice prosthesis (26) containing a reduced diameter hard cartridge (16) disposed in the distal section of a soft outer body (24). The brush includes a reduced diameter distal brush section (12) mounted in a rod (72) having a distal end face larger than the diameter of the cartridge such that the extension of the end of the brush into the opposed esophageal wall is prevented.
