Clinical Evidence

Our commitment to clinical evidence


At Atos Medical, we have a long-standing commitment to furthering clinical evidence by participating in clinical studies all over the world.


This is made possible through our close cooperation with clinicians and patients to ensure that we are working in collaboration to better the lives of people with a laryngectomy. Over the years, many clinical studies have been performed with our products to demonstrate their effectiveness and as such we are proud to say that we have strong evidence to show that they are higher quality products in comparison to our competitors.

Living with a laryngectomy – a quantitative study

In 2018 Atos Medical commissioned the largest global patient study of its kind to better understand how to improve laryngectomy care and quality of life for patients. In total, 1 734 patients in 9 different countries took part in this global study of which there were 159 patients in the UK who contributed.

We have taken insights from this research to help to guide our product innovation for our new Provox Life product range as our ultimate goal is to improve the quality of life for people with a laryngectomy.

The Kelley Circuit

The Kelley Circuit is a new method of managing in-hospital self-ventilating tracheostomy patients that allows for humidification, filtration and closed-circuit suctioning. 

The document below is written by James Kelley et al. from the Wellington Hospital in London, UK and contains a description of the solution, a link to a YouTube video on the solution and 4 case studies.

The Kelley Circuit
