Passy-Muir, Inc.

Inspired by the ingenuity and passion of David Muir, Passy Muir is committed to enhancing quality of life through quality products, and a commitment to excellence in education. Diagnosed with muscular dystrophy, David Muir eventually became ventilator-dependent and as a result, was unable to speak. David experienced firsthand the isolation and frustration caused by the loss of his voice. After months of being unable to communicate, David was determined that he would not continue to suffer in silence. From his wheelchair, he used his scientific background to invent a speaking Valve that could be used on and off the ventilator. David immediately experienced the dramatic positive effect that the Passy Muir® Valve had on his quality of life. His Valve restored his voice and the freedom to communicate with his family, friends, and medical team. David desperately wanted to help others avoid the feeling of helplessness and isolation that he suffered when he was unable to speak. His personal experience fueled his passion and inspired him to find a way to help other tracheostomized and ventilator-dependent patients with his Valve.
