Provox Voice Prostheses
Description
Our indwelling voice prostheses allow for people to speak after total laryngectomy. Voice rehabilitation and pulmonary rehabilitation are important for laryngectomized persons who breathe with a tracheostoma.
The Provox® voice prosthesis (“Provox® 1”)
The original Provox voice prosthesis was released in 1990 to provide an advanced indwelling prosthesis with low airflow resistance and extended device lifetime for tracheoesophageal voice restoration. The voice prosthesis is supplied with a Provox® Guidewire for retrograde insertion.
Provox® 2
The second-generation Provox prosthesis (Provox2) was introduced in 1997. Provox2 is a low-resistance, indwelling silicone voice prosthesis that can be inserted:
- Immediately after primary or secondary TE puncture, without the need for temporary stenting. This retrograde insertion is to be performed by a physician using the Provox® Guidewire.
- As a replacement prosthesis for the Provox (1) or other voice prostheses.
- In an anterograde manner using the single-use insertion tool. This preferred method can be performed by trained health care professional.
Provox® ActiValve®
Provox ActiValve is designed for those who experience short prosthesis lifetime (less than 4 – 8 weeks) caused by early leakage through the prosthesis or negative pressure in the pharynx/esophagus during swallowing or inhalation. The valve and valve-seat of the Provox ActiValve contain magnets that prevent inadvertent opening.
Benefits:
- Reduces the need for frequent replacements in a majority of users who experience short device lifetime.
- Available in three opening forces: Light, Strong and XtraStrong.
