Provox ActiValve

Provox ActiValve is primarily designed for patients who experience early leakage through the voice prosthesis. The blue fluoroplastic material of the valve flap and ring appears insusceptible to destruction by candida. The magnets will prevent the valve flap from opening inadvertently when breathing or swallowing.

Clinical evidence shows that Provox ActiValve has a significantly longer average device life compared to all other voice prostheses.
