The Mission: Dignity Through Speech

Searching for a way to help others, David met with Patricia Passy and told her of the critical need to end the isolation and suffering endured by tracheostomized and ventilator-dependent patients. He explained that his Valve could help others like him avoid the frustration and isolation he suffered as a ventilator-dependent tracheostomy patient. Patricia was moved and vowed to join David in fulfilling the mission of bringing the dignity of speech to patients with tracheostomies. In the words of our founders,

“We at Passy Muir believe that communication is the essence of the human spirit; it is essential to individual rights and dignity. We are committed in our efforts to offer tracheostomized and ventilator-dependent patients a step towards independence and dignity through speech.”

Founded in 1985

In 1985, with their dignity of speech mission always in sight, David Muir and Patricia Passy began the journey of establishing a medical device company to bring David’s Valve to patients throughout the world. They collaborated with engineers to design the manufacturing process, developed clinical studies, obtained FDA clearance, and worked countless hours to bring the company to life.

Working to Fulfill the Mission
David and Patricia advertised in national medical journals and attended national speech pathology, pulmonology, otolaryngology, and respiratory meetings. David was quite the celebrity at these meetings and was always very busy at the exhibit booth discussing the advantages of the Passy Muir® Valve with physicians and clinicians. David loved personally interacting with the individuals prescribing and using his Valve. He was both admired and respected by professionals and patients who were fortunate enough to meet him.

A Worldwide Commitment to Dignity Through Speech

Passy Muir’s mission does not end here at home. The company has brought dignity through speech to tracheostomy and ventilator-dependent patients throughout the world. To meet the needs of the international community, we currently have translations of our clinical Instruction Booklet in many languages.

Commitment to Quality

A solid commitment to quality is the hallmark of the Passy Muir philosophy that is continually integrated into our products and services. “Passy Perfect” is the mandate from our Founder Patricia Passy that we honor each day by providing consistently reliable and high-quality products that assure patients the best opportunity for clear, uninterrupted speech and the added clinical benefits of a bias closed position no-leak design. Each Valve is manufactured and tested to exceed the highest industry standards. Only the best quality Valves may bear the Passy Muir® trademark.

We have dedicated significant resources to the continued development of diagnostic equipment specifically designed to assess speaking Valve performance. We are able to use this state-of-the-art technology to evaluate, test, and continually improve Passy Muir® Valve designs and to further our understanding of the needs of this specialized patient population.

Quality Testing and Standards

Every Valve undergoes visual and microscopic inspection at the time of manufacture and must pass our exacting proprietary testing systems before leaving production.

ISO and CE Mark

As part of our quality commitment, Passy Muir has maintained the CE Marking of Conformance ISO Certification (NSAI) since 1998. Meeting the requirements of these internationally recognized standards ensures that our quality management system proves to be effective, up-to-date, and robust.

In achieving compliance with the ISO 13485:2016 certification, we chose NSAI, a global leader in testing, inspection, and certification. NSAI delivers high-quality services to help companies meet the growing challenges of product quality and safety. NSAI reviews our management system and provides certification to the standard as an independent third-party specialist. This provides our customers with independent assurance that our commitment to quality permeates everything we do so our products can truly be “Passy Perfect” in honor of our founders, David Muir and Patricia Passy.

Honoring David Muir Through Continuing Dedication to Our Mission

David’s spirit, intelligence, innovation, determination, and commitment are a part of every Passy Muir® product produced. We remain conscious of David’s mission in everything that we do at Passy Muir. He is the reason we have the opportunity to give the gift of speech to patients, and it is David’s vision of making his Valve available to every patient with the potential to speak that drives our commitment and inspires our work. We are continually impressed by the patients’ and clinicians’ knowledge of David’s contribution and their loyalty to his mission and his Valves.
