Description

Atos Medical Provox ActiValve Voice Prosthesis is designed for those who experience short device lifetime of Provox1 or Provox2 prosthesis caused by early leakage through the prosthesis due to excessive candida growth and inadvertent opening (and thus leakage) of the valve during swallowing or deep inhalation as the result of negative pressure building in the esophagus or thorax.
