Abstract
A brush for a voice prosthesis containing a reduced diameter hard cartridge disposed in the distal section of a soft outer body. The brush includes a reduced diameter distal brush section mounted in a rod 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.
