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.
